Roslyn Unit Test Issue

Setup

• One classlib project MyClasslib which contains one class MyClass.cs, which has an attribute [Obsolete("My Reason")]
• One console project MyConsoleApp which contains Helper.cs which uses Roslyn to get the attributes from MyClass.cs
• One unit test project Tests which also uses Helper.cs, but prints a different result which is unexpected!

Issue

Using Roslyn to get the attributes of MyClass.cs works as expected, but the same code fails whe running it in a unit test.

Expected output:

System.ObsoleteAttribute("My Reason")

Unit test output:

Obsolete

Why? Please help!
