After the 07/10/2013 Microsoft update, I tried to open Microsoft Visual Studio, then this error showed up
No exports were found that match the constraint: ContractName
Microsoft.VisualStudio.Utilities.IContentTypeRegistryService RequiredTypeIdentity
Microsoft.VisualStudio.Utilities.IContentTypeRegistryService
This error happened to every member's of our group.
The Microsoft Visual Studio Professional 2012:
Version 11.0.50727.1 RTMREL
Appreciate any help on this issue.
