ASP.NET Server does not process pages asynchronously
I have a page with button, and i want to load 2 data grids with data asynchronously by cliking the button.

I am creating an ActionResult in ASP.Net MVC to serve images. With Session state enabled, IIS will only handle one request at a time from the same user. (This is true not just in MVC.)
There is a new app setting in asp.net 4.5
I know there’s a bunch of APIs out there that do this, but I also know that the hosting environment (being ASP.NET) puts restrictions on what you can reliably do in a separate thread.
I’m in the process of updating a library that has an API surface that was built in .NET 3.5. As a result, all methods are synchronous. I can’t change the API (i.e., convert return values to Task) because that would require that all callers change. So I’m left with how to best call async methods in a synchronous way. This is in the context of ASP.NET 4, ASP.NET Core, and .NET/.NET Core console applications.
I have an asynchronous operation that for various reasons needs to be triggered using an HTTP call to an ASP.NET web page. When my page is requested, it should start this operation and immediately return an acknowledgment to the client.
Trying to use new C# 5 async model it was surprising to me AspNetSynchronizationContext is an internal class (as well as AspNetSynchronizationContextBase base). Thus undocumented. But it’s essential to know what it does when utilizing async/await feature within your ASP.NET code. Am I correct that
It does guarantee your continuations will get the same HttpContext.Current as original callers?
It does not guarantee the continuations will execute on the same thread as the callers?
I am trying to understand why and when should I use an async controller action. Eventually, when I use await in it, it will wait for the operation to complete in order to return the View.
During the Techdays here in the Netherlands Steve Sanderson gave a presentation about C#5, ASP.NET MVC 4, and asynchronous Web.
