    In this tutorial we shall add a web api that allows us to get all the records of a table. Please do note, however, that such a query is never done in a real project - it is invariably qualified with some paramaters that return a lesser number of records.


  2. Published: 28-Mar-2022
    This tutorial starts with a beginner's introduction to the concept of web api. After that we create a basic structure of a project that will help us learn about various types of web api - which will be serially covered in the next coming tutorials.

    The purpose of this tutorial is to add the functionality that allows a user to disable his 2-factor authentication. For this we shall have to modify the _LoginPartial page so that the disable 2-factor authentication link is shown to him.


  4. Published: 18-Mar-2022
    Consider a user who has enabled 2-factor authentication as explained in the previous tutorial. Such a user is required to authenticate twice before he can access the pages of a website. The first authentication is through the common login page, and then immediately after that he is redirected to a second login page where he has to enter a validation code obtained from his Google, Microsoft or IOS authenticator app. The purpose of this tutorial is to complete the second login page - also called 2-factor login page.


  5. Published: 03-Mar-2022
    Two factor authentication gives additional security to a login process. But this type of authentication has to be specifically enabled by a user. For this he clicks a button to receive an authentication code or token. This token is provided by the asp.net core app. After that he installs an authenticator app from Microsoft, or from Google or from IOS Play Stores. Then he has to enter that authentication code into the authenticator app and receive a code from that app. This code is then entered into the asp.net core application, and the two factor authentication gets enabled. In this tutorial we shall add a razor page to enable two factor authentication.

    You must have seen on various websites that a user account gets locked if the user makes about three unsuccessful login attempts. The exact same functionality is supported by the Identity API also - and it is possible to configure the number of failed attempts before an account gets locked. If a lockout timespan is specified, then the account remains locked for that specific duration. The default value is 5 minutes, but it can be set to any value. The number of failed attempts and the clock are reset when a user performs a successful login.


  7. Published: 24-Feb-2022
    A sign out link allows a logged user to log out of your website. It is usually shown in the header of a page and close to the name of the logged in user. In this tutorial we shall learn how to implement this functionality.


  8. Published: 24-Feb-2022
    It is a good idea to show the user name of a logged user in the header of each page of a website. And, if the user is not logged in, then the login and register buttons can be shown instead. The best way to implement it is to use partial views in combination with layout pages. This tutorial explains the steps for this.


  9. Published: 19-Feb-2022
    In its simplest terms, a claim is a name-value pair used to verify authorization. For example, you may be authorized to access a page if a claim of name "my_role" and of value "admin" is attached to your identity. In this tutorial we learn how to configure a project for claim based authorization, and how to add claim based authorization to a page.


  10. Published: 16-Feb-2022
    We have seen in the previous tutorial that when a user fills the forgot password form, then he is emailed a link to the reset password page. The link contains a password reset code. Now, in this tutorial we shall add a page for reset password.


  11. Published: 13-Feb-2022
    Very often a user is unable to remember the password that he created for a website. In such circumstances, the forgot password link comes to his rescue - it is one of the most important links on a login form. And, in this tutorial we shall implement the functionality for a forgot password link. Let's proceed!


  12. Published: 11-Feb-2022
    As soon as a new user registers on a website, an account verification email or an sms is immediately sent to him. But it is possible that a user never receives the email, or perhaps he is unable to locate the email that he might have received a few days back. Such a user would ask for the confirmation link to be sent again. This means that we need a mechanism for resending an email to a user. This tutorial explains the steps needed to generate and resend the link to that user.


  13. Published: 10-Feb-2022
    Recall from the previous tutorial that in our program.cs file we have set SignIn.RequireConfirmedAccount = true. This prevents immediate login to a newly registered user. The user is compulsorily required to verify his account through an email or SMS sent to his phone. For this, a link containing a specially generated confirmation token is sent to him. When the user clicks this link then this token is verified on the server side, and the user is informed of the confirmation status.


  14. Published: 08-Feb-2022
    The problem with the built-in registration page provided by ASP.NET Core Identity API is that it contains a lot of tags and bootstrap attributes that make it time consuming to integrate it into a project that doesn't use bootstrap or jQuery. The objective of this article is to explain how to create a neat and simple registration page that can be styled with any css and javascript of choice. We use a simple html table to create a form, but we will not use any css and client side validation because that can always be done with the web designer teams.


  15. Published: 05-Feb-2022
    This tutorial shall continue from the previous tutorial where we have made a basic initialization, and we have also created a database to hold the data of our users. In this tutorial we shall make additional configuration to specify our login and access denied pages. We shall also add a restricted (or protected page) and verify that when an un-authenticated user tries to access it, then he is automatically redirected to the login page.


  16. Published: 24-Jan-2022
    We shall create an identity based project from scratch. Although, visual studio provides a scaffolding for all the various modules, but personally I find all that very difficult to integrate with my own projects and my own css files. That's the motivation for starting from scratch. It will be a series of tutorials. In this first tutorial, I shall add nuget packages, followed by an IdentityDbContext, and finally run a migration to create the database on local sql server.


  17. Published: 21-Jan-2022
    In the previous tutorial we read various properties of an appSettings configuration file. But there is a better method for reading complex properties - such as "Address" - that we read in the previous tutorial. This is done through the options pattern. Let us now read City and ISDCode of the Address property by using the options pattern.


  18. Published: 20-Jan-2022
    We have seen in the previous tutorials that appSettings json file can be used to configure log levels. But this is not the only use of this file - it can, as well, be used to store custom key value data that can be read anywhere in your application. It turns out that log levels are just one of the possible values - there is a lot more that can be done. In this tutorial we shall learn how to store some rudimentary data and then read it back on a razor page.


  19. Published: 20-Jan-2022
    This tutorial continues our previous tutorial where we learnt that if an application is running under development environment, then ASP.NET Core provides a UseDeveloperExceptionPage middleware that catches un-handled exceptions and provides a detailed information about the snapshot state of the application. But that feature is not recommended for production environment - a developer should provide a custom page to filter out the information that finally reaches the display. Let's learn how!


  20. Published: 12-Jan-2022
    We shall create an app using visual studio 2022, running .NET 6. The application will artificially throw an un-handled exception. Then we shall verify that if the application is running under development, then asp.net core automatically provides a safety net to handle this exception, and provides a detailed information about the error. But if the same application is in, say, production, then there is no developer exception page, and the application crashes midway, with no response sent.


  21. Published: 10-Jan-2022
    Logging helps in troubleshooting, it helps in audit, it helps in getting signals of an imminent application crash. This topic explains the terminology of a log message, and also explains how to configure an application for logging, and also how to observe a sequence of log messages.


  22. Published: 07-Jan-2022
    We learn about the finer details of launchSettings.json file. This file contains various launch profiles to start an application in various modes - such as InProcess, OutOfProcess and direct Kestrel. Visual Studio uses this file to populate a dropdown toolbar so that the application can be started in various modes at the click of a button. This allows for easier debugging and testing of an application.


  23. Published: 05-Jan-2022
    An ASP.NET Core application cannot directly accept requests from the internet. For this it needs a server that can face the internet and help it communicate with the calling client on the other side. This means that some sort of coupling is required with a server software. This tutorial discusses various possibilities. Discussion of the launchSettings file is reserved for the next tutorial.


  24. Published: 02-Jan-2022
    This tutorial explains about the various environments like Development, Staging and Production. We also explain how to set them by various methods and how to conditionally check for environments and perform settings.


  25. Published: 27-Dec-2021
    In this tutorial we learn that the recommended strategy for migrations is to migrate through SQL Scripts. We will also learn how to use ef core tools for generating the SQL scripts. The scripts can be fine tuned and reviewed for more accurate results.


  26. Published: 26-Dec-2021
    A real life project evolves over a period of time. This process necessitates additions and alterations to the model classes - properties are added, properties are removed, foreign key relations are established, modified, and even removed. All these changes require a matching change to the database structure. This is a challenging task especially when a project is live and contains critical data that must be preserved and protected against corruption and damage. In this tutorial we learn how the EF Core Migration Tools help us easily achieve migrations without writing a single SQL statement or query.


  27. Published: 24-Dec-2021
    In the previous tutorial we added the EF Core migration tools to our project. We shall now run our first migration to create a blank database and its tables by the code first approach. After that we shall use the SQL Server Object explorer for verifying that our database and its tables have indeed been created.


  28. Published: 21-Dec-2021
    We shall start by creating a simple asp.net core project. Then we shall add nuget packages for a database such as Microsoft SQL Server. After that we shall add a very rudimentary, basic model class, and a DbContext class for specifying the connection string to the built-in SQL Server Express of Visual Studio. Finally, we shall use the package manager console to add the command line tools for ef core migrations.


  29. Published: 20-Dec-2021
    In this tutorial we shall learn an introduction to the database migrations. This feature is provided by entity framework core through its command line tools.


  30. Published: 15-Dec-2021
    In this tutorial we shall first create a docker image of our "Find a Docker" project. After that we shall publish that image to the DockerHub registry of the hub.docker portal. We suggest that you should first go through the chapter "Docker Containerization". That will help you understand the finer detail of docker images, docker containers and the steps for publishing a docker image.


  31. Published: 14-Dec-2021
    In this tutorial we shall learn how to connect an ASP.NET Core application to a SQL Server image that is running inside a docker container. Some data is entered and later verified that the data indeed reached the SQL Server Instance.


  32. Published: 13-Dec-2021
    In this tutorial we shall learn how to pull and run the docker image of Microsoft SQL Server through the Docker Desktop program. In this same tutorial we shall establish a connection to this instance with the Visual Studio SQL Server Object Explorer.


  33. Published: 12-Dec-2021
    This is a walkthrough on uploading a docker image to the docker hub registry. We shall upload the same hellodocker project and then verify the uploaded image by visiting the docker hub portal.


  34. Published: 10-Dec-2021
    In the previous tutorial we were able to run an image in a docker container. The docker container provided a RW memory for our project and also for our sqlite database file. And, we noticed that although the app was running fine, yet the data was not persisting between restarts of the container - it was not getting commited to a persistent store. Whenever we closed and restarted the app we found that the sqlite database started blank, with no data. In this tutorial we shall learn how to attach a virtual disk (or a volume) to your container so that data can persist on your hard disk, so that the data remains available on the next start of the container.


  35. Published: 09-Dec-2021
    This is a walkthrough on running a docker image. We start by explaining the commands for listing the docker images on a computer. Then we explain the commands for running a docker image, and for gracefully shutting down the container. Finally, we examine that when the images are run in this manner, the data is not persisted to disk.


  36. Published: 08-Dec-2021
    This is a walkthrough on creating a docker image with visual studio. We start by creating a simple asp.net core project with sqlite database connectivity, and then explain how Dockerfile can be easily created, followed by a docker image. We have included database connectivity because we shall use the same project for persistence with docker volumes later on.


  37. Published: 06-Dec-2021
    This article is a beginner's introduction to the terminology associated with docker files, docker images and containers. I have kept the explanation bare simple so that it's easy to get started. I have tried to explain the most basic questions like what is a docker, what is it's use for you, and what the basic terms mean in nutshell.

    These are the minimal steps for connecting to a Microsoft SQL Server database with EF Core. A simple application of one textbox form has been used to demonstrate how records can be inserted into a table in a SQL Server database. The tables and database are created automatically by EF Core on the basis of code first approach.

    Following are the minimal steps needed to run a hello world type of razor component that handles a click event. The component will have to be based on blazor because events have to be handled. The events are processed on the server side. If no events have to be handled, then these steps are not required - you should use render-mode=Static

  47. Published: 01-Oct-2021
    A result set can be sorted in ascending as well as descending order. It is even possible to perform a chained sorting by using "ThenBy" and "ThenByDescending" methods. Finally we discuss whether "OrderBy" should be before or after "Where".


  48. Published: 01-Oct-2021
    EF Core translates your LINQ expressions into SQL language queries. However, sometimes it is easier, convenient and faster (as determined by testing) to run queries directly on a database. This tutorial explains how to run SELECT, UPDATE, INSERT, DELETE and execute Stored Procedures and obtain the resultset directly.


  49. Published: 01-Oct-2021
    This is an explanation of Where, Include and the ToList methods from a practical point of view. We have explained when to use which one and how to use. We have also explained how a SQL JOIN can be performed by using the "Include" function of EF Core.


  50. Published: 01-Oct-2021
    This is an explanation of SingleOrDefault, FirstOrDefault and Find methods from a practical point of view. We have explained when to use which one and how to use. We have also explained how Single is different from First, and how Single is different from SingleOrDefault, and also how First is different from FirstOrDefault.


  51. Published: 28-Sep-2021
    A file can be downloaded by returning a FileResult. This article explains how a FileResult is created. Finally, a walkthrough is given that shows a complete upload-download scenario.


  52. Published: 28-Sep-2021
    This is a quick and clean scheme for uploading files to a server. In the first part we demonstrate how to store them into a database table. And, in the second we have a word of caution about putting them into a database. A better strategy would, instead, be to store them on a disk, possibly on a separate partition, and a method for doing this is also explained in the end.


  53. Published: 23-Sep-2021
    Following is a brief scheme on signing out a logged-in user. A function for sign-out is written in the same file as for the login code. Then this function is called from the click of some anchor link and "SignOutAsync" called to kill the login cookie. Finally, a redirection is done to the login page.


  54. Published: 22-Sep-2021
    This is a snippet on showing "You are logged as ..." on every page that an authenticated and authorized user visits. The code can be inserted in a razor page or in a partial page.


  55. Published: 22-Sep-2021
    This article starts with an explanation of "SignIn", and then explains the various steps for a signin process. Finally, we discuss what is a returnUrl, and what is LocalRedirect, and when should it be used.


  56. Published: 22-Sep-2021
    This is an explanation of how an "Area" based ASP.NET Core project can be configured for role and policy based authorization. Authorization can be applied to the entire "Area" directory. We also explain how to specify the login and access denied pages.


  57. Published: 17-Sep-2021
    This is a brief explanation of how to specify single primary key on a model through attributes - but this approach fails when multiple columns are to be set as the primary key. We explain that such a composite primary key has to be set through the DbContext. Finally, we explain how to query a record on the basis of its primary key.


  58. Published: 16-Sep-2021
    SaveChanges can fail if a constraint fails, if a connection error occurs or if any generic error occurs. So it should always be wrapped in a try-catch handler to gracefully handle the DbUpdateException. But how to inform the user about such a failure? One way is to use the built-in server side validation to artificially push the error as a validation failure.


  59. Published: 15-Sep-2021
    This article starts with a brief primer on server side validations and why they should be done. A simple model of just one property is used to explain the whole process - starting from setting the validation error messages to finally inserting validation tags to render the errors. We explain how "asp-validation-for" attributes can be used to display validation errors, and that too, respectively, for each property and at a location just adjacent to its FORM element(see the screenshot below), and also how the ASP.NET Core engine takes care of almost 99% of your work. We also explain how to, optionally, display a gist of all validation errors using the "asp-validation-summary" attribute.


  60. Published: 14-Sep-2021
    A form submit is triggerred by a submit button inside FORM tags. If the method is POST, which is most often the case, then the recommended handler is OnPostAsync. The method should be asynchronous because FORM data is invariably processed through database INSERT and UPDATE queries, which must be done asynchronously. The submitted data can be extracted through the two-way BindProperty. See the linked video for a better understanding.


  61. Published: 14-Sep-2021
    This is an introduction to the most common UI Elements that can be used on a FORM. The article starts with a quick introduction to an html form of only one textbox, and then shows how to translate it to a razor form. Then a checkbox, a radiobuttonlist, and a dropdown are successively added one by one to build a full blown razor form. Data is not posted, a topic reserved for the next tutorials.


  62. Published: 13-Sep-2021
    An anchor tag helper can be used to specify the name of the click event handler. For this the attribute "asp-page-handler" is set equal to the name of the function in the backing class. Read through this tutorial to understand the whole idea. A video is also attached for a first-hand explanation. The tutorial concludes with a walkthrough that demonstrates how a click event can be handled on the server side.


  63. Published: 12-Sep-2021
    Tag helpers provide a standard way of generating html tags in razor pages. They are interpreted on server side. They are of the same syntax as html tags, so a web-designer can style and script them as he does any other html tag. Razor pages are not enabled for tag helpers by default. In this tutorial we learn how to enable a razor page for tag helpers, and we also learn a walkthrough on using the most common "anchor tag helper" to navigate from one razor page to another.


  64. Published: 11-Sep-2021
    This is a quick and complete explanation of how to integrate your razor pages to a framework such as bootstrap, and how to add and manage your custom CSS, JS and image files in your application. We explain various files such as the _ViewStart file, the _Layout file, and the special directory wwwroot. The concept is similar to that of master pages in the classic ASP.NET. The article also contains a linked video that you can watch for a clearer understanding of how we have integrated bootstrap to a simplest ASP.NET Core application.


  65. Published: 09-Sep-2021
    This is the simplest introduction to Razor Pages - why you need them, what they are, and how page events and data could be handled with them. See the linked video for a primer information.


  66. Published: 07-Sep-2021
    This tutorial extends the FORM that we have implemented in the previous tutorial (see link below). Now we add a dropdownlist to that form and observe how easy is it to make an addition to a project that is already CRUD-ready! A dropdownlist must be backed by a C# collection of SelectListItem objects. We also explain how to add an empty required [-Select-] item to such a dropdownlist.


  67. Published: 06-Sep-2021
    This tutorial extends the FORM that we have implemented in the previous tutorial (see link below). Now we add a radiobuttonlist to that form and observe how easy is it to make an addition to a project that is already CRUD-ready! The radiobuttonlist is backed by a hard-coded C# enumeration. We also explain how to specify the conversion from an enum to an INT data-type on the database side.


  68. Published: 05-Sep-2021
    This tutorial extends the one-textbox FORM that we have implemented for CRUD operations in the previous tutorial (see link below). Now we add a checkbox to that form and observe how easy is it to make an addition to a project that is already CRUD-ready!


  69. Published: 04-Sep-2021
    TempData can be used to pass data from one razor page to another. Although QueryString and Session variables can be used to achieve the same objective, yet TempData provides a briefer and cleaner way, and most importantly, it is built into the ASP.NET framework. The most attractive feature of TempData is that the data is automatically cleared away after a first read/extract operation - whenever it takes place. The tutorial ends with a walkthrough where TempData is saved in one page and used for showing a message on a second page. The message appears only once.


  70. Published: 03-Sep-2021
    This tutorial discusses the most desired scenario where data entry form and the already existing records are shown on the same page. Each record has an edit link adjacent to it. When this link is clicked, the record appears in the same data-entry form, so that the user can make changes and submit it. See the image below for a quick understanding of the problem being addressed here. This tutorial also explains a general scheme for editing with EF Core.


  71. Published: 31-Aug-2021
    We start by explaining the general scheme for deleting a record from a table. A foreach loop adds an anchor link to each record. The primary key (id) of each record is set as an attribute of each respective anchor link, and each anchor link also binds to a handler function in the backing class. When such a link is clicked the handler receives that id as a parameter and a C# code carries on the deletion.


  72. Published: 27-Aug-2021
    There is no built-in method for storing DateTime into a session variable in ASP.NET Core. However, the Microsoft MSDN docs suggest that developers can create their own extension methods on ISession, and they have provided code for one such pair of Set<T> and Get<T> methods that use json serialization to store any serializable type as a string. We have copy-pasted their code, and used it to create a small walkthrough that demonstrates how a DateTime instance can be stored in a session variable.


  73. Published: 26-Aug-2021
    This tutorial continues from where we left the tutorial on INSERT query (see the link below for a recap). The code we discussed there has been extended to display the inserted data. In the first part of this tutorial we explain the minimal three basic things that must be done to display data on a razor page. Then we incorporate those additions into the index page and its backing class to show the whole idea in action.


  74. Published: 24-Aug-2021
    This article explains behind-the-scenes mechanism by which "Session" is implemented in ASP.NET Core. We also enumerate the four extension methods that ASP.NET Core provides for reading and writing session variables. After that we present a walkthrough where existence of a Session key is checked to conditionally show a login link, or to show her user-name along with a log-off link that clears the user-name from the Session cache.


  75. Published: 23-Aug-2021
    So this article starts by explaining the various aspects of a partial view from a practical, day-to-day perspective. We have totally removed those parts that are either redundant or too complicated to be of any use for a practical developer. Then we take a small 3-step walkthrough that shows how to create a partial view, and how to consume it in a razor page. We also explain how a conditional menu can be conveniently implemented using the ideas of partial views. Partial Views + Razor Components can add to the confusion of a developer, so we finally conclude with a comparison with razor components.


  76. Published: 18-Aug-2021
    Razor components are stand-alone, embeddable units that replace themselves with pure HTML, CSS and JS markup. They can accept parameters from the host page. We discuss below how they differ from partial pages, and we also discuss the structure of a component page, and also how to use the <component> tag to easily embed a component into a razor page.


  77. Published: 16-Aug-2021
    This is a comprehensive discussion on the need for "areas", and how to practically create "areas", and how, un-like classic MVC, routing occurs out-of-the-box when razor pages are used. We also discuss how tag helpers help us create proper anchor links to pages inside areas. In the end we present a practical login and authorization scheme for projects that use areas.


  78. Published: 15-Aug-2021
    _ViewImports.cshtml is shared by all the razor pages in its peer directory, and in the sub-directories below it. It is like an include file, and it is used to type a list of common directives that would otherwise have to be typed in each of the razor pages. A razor page takes into account the entire hierarchy of _ViewImports files above it.


  79. Published: 14-Aug-2021
    This is a walkthrough on how to obtain user consent for usage of cookies on an asp.net core website. This project uses the ITrackingConsentFeature interface to determine if the user has already given his consent, and also to obtain the correct cookie string as per the http format. The readymade functions of this interface make it extremely easy for a developer to obtain a user's consent.


  80. Published: 13-Aug-2021
    We start this walkthrough with a small introduction to the concept of a cookie, and then we explain the various ASP.NET Core snippets to (a) create a cookie, (b) read a cookie and (c) delete a cookie. And lastly, we create a fully functional application for creating and deleting cookies. You can run the application to see the whole concept in action! We strongly recommend that you watch the linked video for finer details.


  81. Published: 12-Aug-2021
    A form of only one input textbox is POSTed and the data is inserted into a sqlite database. This is a six step walkthrough that starts from creating a model, followed by a DAL based on the DbContext class. We also explain how an application is configured for dependency injection of the DbContext, and also, how the DbContext is extracted from the constructor of a PageModel class, and ultimately used to run a database query.


  82. Published: 08-Aug-2021
