Visual Studio 2012 default .testsettings

Question

I have solution containing a Local.testsettings file. In Visual Studio 2012 we must select manually in each development machine the active .testsettings file to use.

I can not understand how to tell to Visual Studio 2012 that the solution default .testsettings file is the Local.testsettings and to be able to setup that information in some versionned file (.sln or other) so that other users does not need to setup manualy the active settings file.

Answer 1

Edit solution file and add following

 Project("{2150E333-8FDC-42A3-9474-1A3956D46DE8}") = "Solution Items", "Solution Items", "{9BEFB796-EFAA-45DD-810E-8785A8F88FB0}"
        ProjectSection(SolutionItems) = preProject
            CommonAssemblyInfo.cs = CommonAssemblyInfo.cs
            DevBuild.testsettings = DevBuild.testsettings
            Local.testsettings = Local.testsettings
            TraceAndTestImpact.testsettings = TraceAndTestImpact.testsettings
        EndProjectSection
    EndProject

and check in this file and test setting files
