Some time ago, we upgraded the VSTestRunner plugin from version 1.0.4 to 1.0.5. From that time on, all of my .Net projects builds failed in the build step associated with that plug-in.

The error message was:

Path To VSTest.console.exe: …\vstest.console.exe
no file matches the pattern ".\Sources\…\bin\Release\….dll"
".\Sources\…\bin\Release\….dll"Build step 'Run unit tests with VSTest.console' marked build as failure

(Replaced some parts of paths with ellipses)

When I had reverted to the 1.0.4 version, the build step were once again executed succesfully.
