I seem to be regularly getting the error:
System.ArgumentException: Item has already been added. Key in dictionary: 'XamlG' Key being added: 'XamlG'
When I'm creating new classes or folders in the solution viewer. This causes Xamarin Studio to terminate and I have to restart it.
I'm not sure exactly what causes it, just that it happens quite regularly.
I've attached the full ide log which has callstacks.
Ankit, does this look like a mono / msbuild bug?
Fixed in https://github.com/mono/mono/commit/87181decdc79f6181ef495db1f6df24bb6d1064b .
I have checked this issue with latest C9 builds and observed that I am successfully able to create new classes or folders in the solution viewer.
Screencast for the same: http://www.screencast.com/t/jITSIYgw4
I have also tried to reproduce this issue with builds mentioned in ide log but not able to reproduce it.
As of now I am closing this issue. Please feel free to reopen it, if you will encounter this issue again.
