C# generics contraints propagation

Question

This example is a simplification of the real problem, but how can I get this to compile? I would expect the generics constraints to propagate.

Since T is a TClass and TC

The problem is that T doesn't have to be a reference type. Consider:

That would try to call FuncA but int doesn't obey the : class constraint.

So basically you need to add the : class constraint to Func as well:

public void Func() where T : class, TClass
