I have working ASP.NET MVC 3 application. The project is built with VS 2010 and targets .NET 4.0. Now I retargeted it to .NET 4.5 and successfully recompiled. Trying to deploy it to our test server (Windows 2008 R2 SP1) now fails:\[quote\] Error Code: ERROR_APPPOOL_VERSION_MISMATCH More Information: The application pool that you are trying to use has the 'managedRuntimeVersion' property set to 'v4.0'. This application requires 'v4.5'. Learn more at: http://go.microsoft.com/fwlink/?LinkId=221672#ERROR_APPPOOL_VERSION_MISMATCH.\[/quote\]The server has .NET 4.5 installed but there is no app pool 4.5 (because it's inplace upgrade and as i understand 4.0 pool should be fine). The client machine has VS 2012 and so Web Deploy 3 (was Web Deploy 2 previous). I also installed Web Deploy 3 to the server.Tried to re-register ASP.NET with \[code\]aspnet_regiis\[/code\] - no luck.Why do I get the error and how can i fix it? This is so frustrating...p.s.Found similar question about RC but it does not help
