// Desktop compat note: If there is more than one nested type that matches the name in a case-blind match,
// we might not return the same one that the desktop returns. The actual selection method is influenced both by the type's
// placement in the IL and the implementation details of the CLR's internal hashtables so it would be very
// hard to replicate here.
//
// Desktop compat note #2: Case-insensitive lookups: If we don't find a match, we do *not* go back and search
// other declaring types that might match the case-insensitive search and contain the nested type being sought.
// Though this is somewhat unsatisfactory, the desktop CLR has the same limitation.
