Test Platform Migration Known issues

Here are the current known issues you may face when running tests, along with available workarounds.

Change in Thread.CurrentPrincipal value

• Issue: Tests that depend on Thread.CurrentPrincipal may fail. This is due to change in inter process communication in Test Platform.
• Workaround: Use an alternative like System.Security.Principal.WindowsIdentity.GetCurrent()

Change in test execution processes name

• Issue: Tests that depend on the name of the currnet running process may fail.
• Workaround: Tests run in one of following process vstest.console.exe, testhost.exe, testhost.x86.exe or dotnet.exe based on run configuration (/Platform and /Framework). If the tests depend on the process name, then update the tests accordingly.
