如何为 ASP.NET WebForms、MVC 和 CORE 拥有一个通用的 HttpContext

Question

I'm working on a Nuget library which can be used for web applications (WebForms, MVC, CORE) and will be published for both .NetFramework and .NetStandard.

In my library I need to access the HttpContext for reading the Request and also for redirecting and writing in the Response object.

What's the best way to have a common HttpContext for all three frameworks WebForms, MVC and CORE?

Note that Microsoft.Owin is not compatible with .NetStandard and also in WebForms and MVC there is a System.Web.HttpContextBase class which is completely different in .NETCore projects and there we have Microsoft.AspNetCore.Http.HttpContext.

Your library could be organized this way:

1. Define adapter interfaces (over HTTP context and etc ) in shared source project
2. Define implementations of all those interface in concreate Core or Classic project - create both. There you should have 3 projects in your solution.
3. Now your library is 4th project it should be multitarget , use conditional symbols to enable or disable "Classic" or "Core" adapters. Use adapters to access " Http Context and etc ".
