As I described in my previous post, the Identity API endpoints are new in .NET 8, and are meant to provide an “API” version of the default Razor Pages UI. The exception is CSS paths which are relative to the page source page or code calling them internally. Many say that means those absolute web paths break if you move them. But I argue, why would you need to reference the root for your website then suddenly change that?

An example of an answer-set programming language is AnsProlog, a specialized version of Prolog that avoids infinite loops when solving complicated problems. And because every Web Forms page inherits from the System.Web.UI.Page class, this also means that you can easily implement your own Page classes with your own logic as well. Server controls, rapid development, drag and drop interface and a front-end / back-end file system that ensures separation of logic.

Short for Active Server Page, an ASP page is a dynamically created web page that ends with a .ASP extension that utilizes ActiveX scripting, usually VBScript or JScript code. The .aspx extension is used for Web pages that use Microsoft’s ASP.NET. These pages are called “Web Forms” and often contain (X)HTML, and ASP.NET code.

By exposing minimal APIs for user management functionality, you can build the UI in your SPA app, seamlessly integrating the APIs without the impedance-mismatch of using Razor Pages. No need for full-page refreshes; no clashes in styling; everything feels “native” to your app. The Identity API endpoints were added with the intention of improving this scenario, as I’ll discuss in the next section. Unlike a .NET Core application, Web Forms rely on running in the Windows ecosystem under the full .NET Framework.

However, the modern opinion of most security professionals has shifted. The Identity endpoints have received a fair amount of publicity for .NET 8, which is not surprising, because many people have been asking for something like this for some time. It’s fairly obvious how these steps tackle the main complaints I described in the previous section.

Interpreted code is not directly executed by the machine, but must be read and interpreted each time before being executed. Compiled code is usually faster and more scalable than interpreted code, and can do anything interpreted code can do. Examples of interpreted languages include PHP, JavaScript and Ruby. You’ve created a complete ASP.NET Core Web API for CRUD operations with a MySQL database using Entity Framework Core.

It is specially designed to work with HTTP and for web developers to create dynamic web pages, web applications, web sites, and web services as it provides a good integration of HTML, CSS, and JavaScript. It used to be that developers had to buy expensive software (called Integrated Development Environments, or IDEs) in order to build applications. Companies with more than 5 developers must purchase a license to use Visual Studio, but the cost is competitive with professional IDEs for other platforms. Microsoft also provides Visual Studio Code, a lighter-weight IDE and editor, which is free for everyone, including corporations. ASP.NET is an open source, server-side web application framework created by Microsoft that runs on Windows and was started in the early 2000s.

ASP was introduced in 1998 by Microsoft as its first server-side scripting language. The file extension of ASP pages are .asp and are normally written in VBScript. It is an old but still powerful tool for making dynamic web pages. ASP is a technology (much like PHP) for executing scripts on a web server. The one area that ASP Web Forms does not excel in in, is in its ability to separate business logic out from the primary code base. With an MVC project, you have the Model which is the structure of the application data and the data itself.

And that’s because there are alot of things that ASP Web Forms simply wasn’t designed to do. What type of database to use is an important decision when developing a web application. ASP.NET applications can use all of the popular databases, including Microsoft SQL Server, MySQL, MariaDB, Postgres, MongoDB and CouchDB. asp.net is used for While Microsoft SQL Server can require expensive software licenses for complex deployments, the free Express version is suitable for the vast majority of websites. All of the other databases mentioned here are free and open source. The compilation process also provides validation that all of the code is consistent.

If for example, you have a button on the page that when clicked validates a login, you can simply create click event-handler and let the framework worry about creating the actual HTTP request and response logic. For line-of-business apps, your company likely already has some sort of single-sign-on central authentication mechanism. First of all, the Identity endpoints don’t support any sort of external authentication mechanism. That means users of your app will always need a dedicated username and password for this app alone. But if you’re building an app for a business, whether it’s a line-of-business app or public-facing, that’s likely not the approach you want longer term.

All the middleware does it to create a new Stopwatch and add the elapsed ms as a custom response header named X-Took. I know that there are alternative and better ways of measuring performance on an ASP.NET Core API but that’s not really the focus here so play along. Sample ASP.NET web application that consumes an Azure Cosmos DB (NoSQL), it connects to Azure Cognitive Search and Azure OpenAI with our own data (preview). I’ve tried disposing the filestream before returning the file to the user, which seems to have had no effect.

  • Both technologies enable computer code to be executed by an Internet server.
  • High speed, low cost, and vast language support are among the most significant benefits.

In this post I look more at the design of these endpoints, the implications of using them, and finally, whether or not I think it’s a good idea to use them at all. These are UNIX conventions that just mean to point to the local folder or the same folder the calling code is in. There are cases for their use, but the end result has zero affect on Web Paths.

This isn’t just vague opinions, there’s a draft RFC from the IETF discussing recommended architectures, and they mostly focus on how to keep the tokens out of the browser. I’ll describe each of these approaches in detail in a future post. In the following sections, I’ll discuss some of the key issues I see. The first two points are fundamental issues with the concept of the Identity endpoints. The latter points are problems that could feasibly be addressed in future versions of the Identity endpoints.
