How Routing works in ASP.NET Core?

Routing is used to handle incoming HTTP requests for the app. Routing find matching executable endpoint for incoming requests. These endpoints are registered when app starts. Matching process use values from incoming request url to process the requests. You can configure the routing in middleware pipeline of configure method in startup class.


    app.UseRouting(); // It adds route matching to middlware pipeline

    // It adds endpoints execution to middleware pipeline
    app.UseEndpoints(endpoints =>
    {
    endpoints.MapGet("/", async context =>
    {
    await context.Response.WriteAsync("Hello World!");
    });
    });

ASP.NET Core | Change Token

A  change token  in ASP.NET Core is a general-purpose, low-level building block used to track state changes. Let me break it down for you: IChangeToken Interface : The  IChangeToken  interface propagates notifications that a change has occurred. It resides in the  Microsoft.Extensions.Primitives  namespace and is implicitly provided to ASP.NET Core apps via the  Microsoft.Extensions.Primitives  NuGet package. Key properties: ActiveChangeCallbacks : Indicates whether the token proactively raises callbacks. If set to  false , a callback is never called, and the app must poll  HasChanged  for changes. HasChanged : Receives a value that indicates if a change has occurred. Additionally, it includes the  RegisterChangeCallback(Action<Object>, Object)  method, which registers a callback invoked when the token changes 1 . ChangeToken Class : The  ChangeToken  class is static and used to propagate notifications that...

ASP.NET Core | Open Web Interface for .NET (OWIN)

Image
ASP.NET Core supports the Open Web Interface for .NET (OWIN). OWIN allows web apps to be decoupled from web servers. It defines a standard way for middleware to be used in a pipeline to handle requests and associated responses. ASP.NET Core applications and middleware can interoperate with OWIN-based applications, servers, and middleware. Running OWIN middleware in the ASP.NET pipeline ASP.NET Core’s OWIN support is deployed as part of the  Microsoft.AspNetCore.Owin  package. You can import OWIN support into your project by adding this package as a dependency in your  project.json  file: "dependencies" : { "Microsoft.AspNetCore.Server.IISIntegration" : "1.0.0" , "Microsoft.AspNetCore.Server.Kestrel" : "1.0.0" , "Microsoft.AspNetCore.Owin" : "1.0.0" }, OWIN middleware conforms to the  OWIN specification , which requires a  Func<IDictionary<string,   object>,   Task>  interface, and...

ASP.NET Core | Performance Diagnostic Tools

Visual Studio Diagnostic Tools The  profiling and diagnostic tools  built into Visual Studio are a good place to start investigating performance issues. These tools are powerful and convenient to use from the Visual Studio development environment. The tooling allows analysis of CPU usage, memory usage, and performance events in ASP.NET Core apps. Being built-in makes profiling easy at development time. Application Insights Application Insights  provides in-depth performance data for your app. Application Insights automatically collects data on response rates, failure rates, dependency response times, and more. Application Insights supports logging custom events and metrics specific to your app. Azure Application Insights provides multiple ways to give insights on monitored apps: Application Map  – helps spot performance bottlenecks or failure hot-spots across all components of distributed apps. Azure Metrics Explorer  is a component of the Microsoft Azure portal...
