MSTest publishing failed after TFS update3 installed

all We just upgraded the TFS and build agent from 2013 to 2013 update 3, and our UT failed because MStest failing to publish results to TFS. I also tried to use command line on the build agent as follow "C:\Program Files (x86)\Microsoft Visual Studio 12.0\Common7\IDE\MSTest.exe" /publishresultsfile:"C:\temp\Result _2014-08-12 11_38_49_.trx" /publish:"TFSUrl" /noprompt /publishbuild:"vstfs:///Build/Build/619" /teamproject:"TeamProjectName" /platform:"Any CPU" /flavor:"Release" and got the same error below

Also a windows event is raised as below

Another story 1, we have 2 build agents A and B, on the first day, we upgraded A and found MStest publish failed on A and succeed on B, on the other day after B was upgraded , both of them couldn't publish the UT results.

Another story 2, MSTest 2010 can publish the results on the Build agent successfully.

Do you have any idea? Thanks in advance!

Solution

I know this is not a final answer, but I walked around this issue, and currently my team build system worked well.

From the exception, I know this is a version-mismatch between managed assemblies (Microsoft.TeamFoundation.TestManagement.*) and un-managed dlls (not sure what are them). So I just tried to down-grade Microsoft.TeamFoundation.TestManagement.Common.dll and Microsoft.TeamFoundation.TestManagement.Client.dll from 12.0.30723.0 to 12.0.21005.1, and everything begin to work.
