Hi, I have the same problem with VS2010. Opening any kind of project (even non-Xamarin) makes VS crash. It crashes only when I install Xamarin, and it stops crashing when I remove it.
Are you able to install the Xamarin extensions and then run Visual Studio from the command line with an extra Log parameter?
devenv /log <path/name of log file>
Then post the resulting log file to this thread.
See the attachment.
