I'm using InternalsVisibleTo attribute to make some internal classes visible to the unit test suite.
While it's allowing me to create instances of internal classes, I cannot create a class that inherits from an internal class.
Is this behaviour expected? If it is, there's some other way to achieve what I want?
Edit: As pointed by @Grant Thomas, I did not say what I want. What I want is to create an instance of an abstract internal class. It's not that class I'm testing, but the class I'm testing have it as a dependency.
