CREATIVE CODE DESIGN

Move implementation into a method not marked as [TestMethod] into a new method marked with Conditional("DEBUG") and call it from the [TestMethod]... Sad but true and by design. With Conditional("DEBUG"), the compiler will merely ‘void out' calls to the method marked with that attribute. The method itself is still compiled in. Thus, when mstest looks for test to run, it finds all of the Conditional("DEBUG") methods regardless of build configuration... The effect of this fact is that unit test execution cannot be conditionalized for Release Mode. Hence the unit tests will still execute and fail, if you have debug-specific configuration in the implementation.
