A call to Debug.Fail in C# code does not include a descriptive message.
A violation of this rule occurs when the code contains a call to Debug.Fail which does not provide a description for the end-user. For example, the following call includes a description message:
Debug.Fail("The code should never reach this point.");
How to Fix Violations
To fix an instance of this violation, add a descriptive message to the Debug.Fail call which will appear to the end user when the assert is fired.
