Run Visual Studio Test task in 64bit

Run Visual Studio Test task in 64bit

All of our managed assemblies are build with the any cpu target and we can use both the 32-bit and 64-bit task runner of Azure Pipelines.

One of our projects uses a C++ DLL that is either in 32-bit or 64-bit and we need a specific test runner (the 64-bit one to be exact) to not fail with a System.BadImageFormatExeption.

By default the Visual Studio test runner will start a 32-bit process. If you need to use the 64-bit version you need to specify extra arguments with supplying otherConsoleOptions to the task:

- task: VSTest@2
  displayName: Run tests
    testAssemblyVer2: |
    runTestsInIsolation: true
    codeCoverageEnabled: true
    otherConsoleOptions: '/Platform:x64'

Note: The Visual Studio Test task sports a parameter called platformwhich does not change the architecture of the test runner executable.
