Nasty bug rendered by installing MS Source Analysis for C#
If you have installed the source analysis tool recently released by MS and have since tried to view the properties of a project then you will be greeted with the following error:
An error occurred trying to load the page.
COM object that has been separated from its underlying RCW cannot be used.
This is a very annoying bug, if you uninstall the tool all is fine.
They are aware of the issue.
