The specific 2.0 version is no longer supported; it requires 3.5 because
there are a few uses of LINQ functions in the codebase, and ISTR there
being some other 3.5-only APIs that are used in the guts of the DLR as well.

Thanks to Microsoft's bizarre versioning scheme for .NET 2.0 to 3.5, there
are a few things that still refer to "v2" when they actually mean 3.5. 2.0
and 3.5 both use the 2.0 runtime, but add extra libraries in 3.0 and 3.5.

So in short: for now, 3.5 is the minimum version that is supported.
