Title: FIX: Cast exception when Running all tests

When trying to run all tests, got
Unable to cast object of type 'ImplemenationCTestTestAdapter.CTestCase' to type 'Microsoft.VisualStudio.TestPlatform.ObjectModel.TestCase'

Indeed, CTestCase do not inherit from TestCast (which is sealed) so we cannot
use Cast to convert from CTestCase to TestCase.
Use conversion operation inside Select instead
