[Mono-aspnet-list] Mono Asp.NET MVC 4 and async actions

[Ventsislav Mladenov]

HI, all
   Today I tried to use async actions under Mono 3.0.6, I changed one
action method which works correctly to async action:
Change Controller to AsyncController
Change action declaration from:

public ActionResult Index  to
public Task<ActionResult> Index

And now I'm getting error:
System.InvalidOperationExceptionThe view 'Index' or its master was not
found or no view engine supports the searched locations. The following
locations were searched: ~/Areas/Reports/Views/Activities/Index.aspx
~/Areas/Reports/Views/Activities/Index.ascx
~/Areas/Reports/Views/Shared/Index.aspx
~/Areas/Reports/Views/Shared/Index.ascx ~/Views/Activities/Index.aspx
~/Views/Activities/Index.ascx ~/Views/Shared/Index.aspx
~/Views/Shared/Index.ascx ~/Areas/Reports/Views/Activities/Index.cshtml
~/Areas/Reports/Views/Activities/Index.vbhtml
~/Areas/Reports/Views/Shared/Index.cshtml
~/Areas/Reports/Views/Shared/Index.vbhtml ~/Views/Activities/Index.cshtml
~/Views/Activities/Index.vbhtml ~/Views/Shared/Index.cshtml
~/Views/Shared/Index.vbhtml

The project is on .net 4.0 and uses asp.net mvc 4

Then I tried the code under MS.NET and it works.
