I changed the target framework of a WPF application to use .NET 4 and now Visual Studio refuses to run it when I press F5. There are no errors, nothing in the build window, it just does nothing.
If I run it manually outside Visual Studio, it runs. If I change it back to .NET 3.5, it runs.
I tried running with logging enabled, but the log didn't have anything debugging-related. But here it is anyway. Anything else I should try?
