TFS Integration Tools–Issue: AnalysisProvider not found
Explains how to resolve the "AnalysisProvider not found" error in TFS Integration Tools by updating the .NET Framework version from 3.5 to 4.0 and …
TL;DR; Explains how to resolve the “Sequence contains no elements” error in TFS Integration Tools by removing outdated TFS 2008 adapter files to prevent plugin loading issues.
According to TFS Integration Tools – March 2012 Release there was a fix for “Resolving VC namespace conflicts results in System.InvalidOperationException: Sequence contains no elements” in the March release. I am using the March release and:
Figure: Sequence contains no elements
On examining the log files it looks like the Migration Shell is trying to load the TFS 2008 VC Adapter even though we are using the TFS 2012 VS Adapter. As I do not have anything to do with TFS 2008 installed I get, as you would expect, an “Unable to load one or more of the requested types”.

Well that sucks…
One work around that I found with the help of Bill Essary is to remove the “Tfs2008VCAdapter.dll” files from the folder so that they can’t even be loaded.
Figure: Get rid of the offending adapters
Woot… that solved my issue… did it solve yours?
