I am trying to do reverse, where i want to push result into TFS testResult. I have JAvaScript results as xml file which are generate by using grunt, want to push/publish those results into TestResult on TFS Build Server.

Any Ideas how can i do that ?

How get files from a changeset ?

I prefer Microsoft.TeamFoundation.Client if I can.
