Why isn't there a Guid.IsNullOrEmpty() method

Question

This keeps me wondering why Guid in .NET does not have IsNullOrEmpty() method (where empty means all zeros)

I need this at several places in my ASP.NET

For one thing, Guid is not nullable. You could check:

myGuid == default(Guid)

which is equivalent to:

myGuid == Guid.Empty
