Equivalent of Tuple (.NET 4) for .NET Framework 3.5

Question

Is there a class existing in .NET Framework 3.5 that would be equivalent to the .NET 4 Tuple?

Answer 1

Yes, you can just use Tuple.cs from mono:

You require the dependencies as well:
Tuples.cs
IStructuralComparable.cs
IStructuralEquatable.cs

You just put a

#define NET_4_0

in front of every

#if NET_4_0

and there you go, a feature-complete implementation of System.Tuple for .NET 2.0.
