Visual Studio 2010 Beta 2 has been running relatively good for a while now, but today, I had a crash in the WPF designer, which crashed Visual Studio, and it could not start again.
When trying to launch, I just get a “The application cannot start.” error. No more info. That’s it.
The problem is caused by the Visual Studio environment not saving correctly. It saves and cleans up with the IDE closes. In my case, the IDE didn’t close correctly, so the settings weren’t saved.
So, to fix it simply, run devenv /resetuserdata
Be warned: all of your settings are going to be erased. Any fonts that you had configured, your MRU’s, etc. Everything will be reset to “factory settings”.
But at least Visual Studio loads again.
