C# file to demonstrate the bug

The attached C# code fails to compile with this error:

Program.cs(16,2): error CS0314: The type `TVector' cannot be used as type parameter `T' in the generic type or method `Program.BoundingBoxN<T>'. There is no boxing or type parameter conversion from `TVector' to `Program.IVector<TVector>'
D:\scratch\ScratchCSharpProject\ScratchCSharpProject\Program.cs(58,29): (Location of the symbol related to previous error)
Compilation failed: 1 error(s), 0 warnings

The same code compiles with the Microsoft C# Compiler.
