An ASP.NET tutorial is designed to equip you with the tools and techniques needed to create modern, intuitive applications. An ASP.NET course may begin by covering the basics of the framework, and then reviewing Web Forms, ASP.NET MVC, and ASP.NET Web Pages. However, there are hardly any rich apps which do not require even the basic database connectivity. So how does an app – say a gaming app that maintains a leaderboard – communicate with application servers and databases which maintain application data remotely? The classes that will be used by both client and server are put in the shared project. The server side and client side logic exists in their respective projects and both of these refer to the shared project without referring to each other.
In particular, this release brings new options for authentication and authorization for ASP.NET Core Identity. There’s a common belief that cookie-based authentication should be used for traditional server-side page-rendered applications, while token-based authentication is for SPAs and native applications. However, the current trend in authentication for SPAs seems to be token-based rather than cookie-based, and ASP.NET Core Identity didn’t support it. The only option provided with the built-in SPA templates was based on Identity Server, a third-party OpenID Connect server.
ML & Data Science
With version 1.0 of the .NET Framework, it was first released in January 2002. So a question comes to mind that which technology we were using before the year 2002 for developing web applications and services? The app actually runs on the browser, everything (event handling, UI refresh etc) is done on the client side only. These are so called ‘static apps/websites’ which, once loaded, require nothing else to execute. Imagine a single player, flash style games – they don’t need connection to a database/application server. However, without having to do anything specific, DPA does make you aware of potential performance issues before your application goes to production.
- In the last few years, I’ve been focusing on simplifying the developer experience with Identity and related topics, especially in the .NET ecosystem.
- NuGet Serilog package is a logging library for .NET applications that provides a flexible and extensible approach to event logging, allowing developers to capture information on application behavior.
- So far we’ve only created methods to return data from the database.
- It has also provided a set of web pages that allow users to register, authenticate, recover passwords, etc.
Cookie-based authentication is the typical approach used by the traditional server-side rendered web page model. This is the model used by ASP.NET Core MVC and Razor Pages, to put it bluntly. In this type of authentication, a server-generated cookie proves successful user authentication and represents the user session.
Token-based authentication
In ASP.NET 8, identity endpoints were introduced to simplify the process of adding user accounts to ASP.NET Core API apps used with SPAs or mobile. These endpoints streamline the user management process by providing an alternative to the traditional Razor Page Identity UI pages. Additionally, http://kctt.spb.ru/?rz=fx a new endpoint is included for retrieving bearer tokens, which can be used for authentication. These changes directly address the concerns mentioned earlier, making it easier to create a user-friendly and integrated experience within your app, with no full-page refreshes or styling conflicts.
From a user experience perspective, the full-page refreshes of Razor Pages can be a major drawback especially compared to the fluidity of SPAs. On the other hand, from a developer’s perspective, if you want the default pages to be compatible with the rest of your application, you may need to update more than 30 pages. Moreover, the default Razor Pages UI uses traditional cookie-based authentication, not bearer tokens. ASP.NET is a free, open-source web development framework created by Microsoft.
Cookies, Tokens, or JWTs? The ASP.NET Core Identity Dilemma
EF Core uses the concept of “model first,” where you define your data model using classes and properties in your code. From these classes, EF Core can automatically create the database schema, execute queries and manage change tracking so that database updates are reflected in object instances in your application. Yes, it can be, depending on your career goals and how you envision your workflow. With its high performance and efficiency, it allows developers to build web applications faster.
ASP.NET Core includes a managed cross-platform web server, called Kestrel, that you would typically run behind a production web server like IIS or nginx. Main uses WebHostBuilder, which follows the builder pattern, to create a web application host. The builder has methods that define the web server (for example UseKestrel) and the startup class (UseStartup). In the example above, the Kestrel web server is used, but other web servers can be specified.
Custom Authorization Policies
Slow web pages may make your users or customers abandon your web application, even before they’ve had a proper look at it. You’ve likely also been frustrated working with a web application that is slow to load. Developer reactions to the new Identity API make me think that they have been waiting for a built-in OpenID Connect and OAuth 2.0 implementation. They would probably expect Microsoft to have replaced Identity Server with its own OpenID Connect server. However, this may sound somewhat contradictory, since many have complained about the complexity of Identity Server in simple authentication scenarios. Prior to ASP.NET 8, adding a parameterized authorization policy to an endpoint required writing a lot of code.
