Resolution for C# Unit test project error : UTA002: TestClass attribute cannot be defined on generic class

if you ever have tried writing a generic class with attribute set to [TestClass] ass below , you might have got Runtime error which begin with “UTA002: TestClass attribute  cannot be defined on generic class”  & follows multiple such codes UTA004 or UTA005 or UTA006 for various Test method attributes


public class CustomEntityTestBase<T> : CustomEntityBase<T>


after trying multiple workarounds finally what made these errors go away is by putting an “abstract” keyword to the class declaration shown as below


public abstract class CustomEntityTestBase<T> : CustomEntityBase<T>


hoping this tip will save you a lot of time if you are struggling like me for this error and you don’t want to try complex workarounds as suggested in the internet
