I Have VS 2015 only installed on my TFS 2013 build server, and get the following error:
TF900547: The directory containing the assemblies for the Visual Studio Test Runner is not valid ''.
Other sites say to install VS 2013, but why would I have to install VS 2013 on the build server to run unit tests when I have VS 2015 installed?
I have the following switches on my build:
/p:VisualStudioVersion=14.0 /tv:14.0
(This is not a duplicate question as I am using TFS 2013 and am trying to use the Agile Test Runner not MS Test)
