title: How to set .net Framework 4.5 version in IIS 7 application pool
body: <p>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: <a href="http://blogs.msdn.com/b/pfxteam/archive/2012/03/03/10277166.aspx" rel="noreferrer">http://blogs.msdn.com/b/pfxteam/archive/2012/03/03/10277166.aspx</a>).</p>
  
  <p>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)? </p>
