In .NET, is GC.MaxGeneration never 2?

As far as I understand, there are three generations of garbage collectors - 0, 1 and 2 for all versions of .NET.

Are there any circumstances under which a check GC.MaxGenerationwill lead to anything other than 2? Are there GCs for other frameworks that have a different number of GC generations?
