I installed the Visual Studio 11 Beta and suddenly all the async action methods I had created under the VS 11 Developer preview started hanging (apparently this issue: http://blogs.msdn.com/b/pfxteam/archive/2012/03/03/10277166.aspx).
My app is using v4.0.30319 as the Framework Version, but there is no option to use 4.5. I repaired my .net 4.5 install to be sure, but nothing. Is there a way to configure this in IIS? Do I need to bin deploy the files (and if so which)?
Expand the server name, and select Application Pools. Select the app pool, and open the Basic Settings. Set the . NET CLR version to the newer version, and select OK to save your changes.
There is no 4.5 application pool. You can use any 4.5 application in 4.0 app pool. The .NET 4.5 is "just" an in-place-update not a major new version.
Go to "Run" and execute this:
%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir
NOTE: run as administrator.
