Failed to queue test run ... QTAgent32.exe

After freshly rebooting, I get the error in the title if I attempt to debug even the simplest, most trivial unit test.

It's the same problem as this question, but I don't see a good answer in there.

Any help anyone could provide would be appreci开发者_StackOverflow社区ated immensely.

We were able to solve this problem by turning off IntelliTrace. Tools->Options->IntelliTrace, uncheck "Enable IntelliTrace".

This is a known bug per microsoft and one of the work arounds fixed it to me:

It looks like Visual Studio insists building projects that started their life as a WCFService Application. After removing the WCF Service Application specific tags from the csproj xml files, unit tests work every time. I removed the following tags: Under Property Group: Remove ProjectTypeGuids and StartArguments Remove entire ProjectExtensions node

FYI, to edit a project file first right click and unload the project. Then right click again and edit project file. The removed attributes shouldn't affect the running of the WCF service
