After installing 2141. I am unable to do anything with a VS2010 Modeling project or its diagrams.
I get the following error:
Cannot evaluate the item metadata "%(FullPath)". The item metadata "%(FullPath)" cannot be applied to the path "obj\Debug|Any CPU\ModelingProject1.dll". Illegal characters in path. C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets
Luckily, If I uninstall R# I then I am able to do what I need to do with Modeling
