Fixes bug with HttpContext.Current

Now passes through HttpContext.Current to the thread which executes the ActionResult.
(Fixes AutoFac in ASP.NET application.)

Dependency-Injection & async support

Now targets .NET 4.7.2. Supports async Task<ActionResult> action methods on controllers.
Acquires Controller instances from DependencyConfig.Current instead of Activator. (Works as
before, but also supports Dependency Injection frameworks like AutoFac and others.)

Improves NuGet dependencies

NuGet dependency is now on Microsoft.AspNet.Mvc rather than (legacy) AspNetMvc.

Also, NuGet dependencies within the code have been cleaned up and pared down.

The Example project is a bit tidier too.

NuGet: Dysphoria.Net.UrlRouting 2.2.1

Usability Improvements & File Upload

Improvements:

• Now deals correctly with form submission, including file uploads.
• Adds more fluent API for specifying HTTP methods, via extension methods.

Fixes:

• Correctly parses querystring parameters (using invariant culture) and form parameters (using user's culture).
• Fixes reported fault with ‘cannot find method’ error (seen on .NET 4.5 and later).
