ASP.NET Core | Service Lifetimes

When Services are registered, there is a lifetime for every service. ASP.NET Core provides the following lifetimes.

  • Transient - Services with transient lifetime are created each time they are requested from service container. So it's best suited for stateless, light weight services.
  • Scoped - Services with scoped lifetime are created once per connection or client request. When using scoped service in middleware then inject the service via invoke or invokeAsync method. You should not inject the service via constructor injection as it treats the service behavior like Singleton.
  • Singleton - Service with singleton lifetime is created once when first time the service is requested. For subsequent requests same instance is served by service container.

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...

How will you improve performance of ASP.NET Core Application?

Cache aggressively Caching is discussed in several parts of this article. For more information, see  Overview of caching in ASP.NET Core . Understand hot code paths In this article, a  hot code path  is defined as a code path that is frequently called and where much of the execution time occurs. Hot code paths typically limit app scale-out and performance and are discussed in several parts of this article. Avoid blocking calls ASP.NET Core apps should be designed to process many requests simultaneously. Asynchronous APIs allow a small pool of threads to handle thousands of concurrent requests by not waiting on blocking calls. Rather than waiting on a long-running synchronous task to complete, the thread can work on another request. A common performance problem in ASP.NET Core apps is blocking calls that could be asynchronous. Many synchronous blocking calls lead to  Thread Pool starvation  and degraded response times. Do not  block asynchronous execution by...
