DotNet UnitTest AppConfigFiles

Issue

When runing MsTests, the app.config file created is copied to the output folder with then name of the Test Project (Ex: MyTestProject.dll.config) But the process hosting is testhost.dll and the file shoul dbe named testhost.dll.config.

To automatically copy the file with the proper name, a simple hack in the csproj will solve the issue :
