“No exports were found that match the constraint” error in Visual Studio

The Issue:

I tried to open a project under Micro Focus Enterprise Developer for Visual Studio 2012, and received this error:

 “Cobol Editor MF package did not load correctly. Not able to access any component already saved.”

This was seen in the ActivityLog.xml file:

<description>The CTM file is out of date and should be deleted and rebuilt, but the file &apos;C:\\ProgramData\\Microsoft\\VisualStudio\\11.0\\1033\\devenv.CTM&apos; could not be deleted.</description>

I was able to bypass this error by clicking on a box which allowed the error not to appear any more. But next these errors appeared:

"No exports were found that match the constraint:

    ContractName

MicroSoft.VisualStudio.Utilities.]ContentTypeRegistryService

    RequiredTypeIdentity

MicroSoft.VisualStudio.Utilities.]ContentTypeRegistryService"

The Resolution:

This is not an error originating from the Micro Focus product. It is a Microsoft error. However the resolution is this:

Clear the Visual Studio Component Model Cache. Delete or rename this folder:

%LocalAppData%\\Microsoft\\VisualStudio\\11.0\\ComponentModelCache

or

%LocalAppData%\\Microsoft\\VPDExpress\\11.0\\ComponentModelCache

and restart Visual Studio. The issue will have been resolved.
