will that memory get de-allocated after completion of unit test?

Quote:

"It is simply false that the choice of whether to use the stack or the heap has anything fundamentally to do with the type of the thing being stored. The truth is: the choice of allocation mechanism has to do only with the known required lifetime of the storage."

the .NET String class is a reference type, correct?

No, it's a value type.

it's easier to think of string as a value type, even though it isn't

You could check the type in a single method and route it to one of two private methods?

I'm not returning a collection of generics, so it can't pick the appropriate overload.

MyMethod(Enumerable.Range(1, 42)); // Calls IEnumerable overload
MyMethod(new[] { 1, 2, 3 }); // Calls T overload
MyMethod(new List<int> { 1, 2, 3 }); // Calls T overload

MyMethod(Enumerable.Range(1, 42)); // Calls IEnumerable overload
MyMethod((new[] { 1, 2, 3 }).AsEnumerable()); // Calls IEnumerable overload
