Actually, I guess there is supposed to be an actual implementation. Sort of.
It's an empty method on the class that gets implemented by com interop code.

[System.Runtime.CompilerServices.MethodImpl(System.Runtime.CompilerServices.MethodImplOptions.InternalCall)]
[return:
System.Runtime.InteropServices.MarshalAs(System.Runtime.InteropServices.UnmanagedType.BStr)]
public virtual extern string
IWMPStringCollection2_Item([System.Runtime.InteropServices.In] int lIndex);

But this isn't IWMPStringCollection_Item. In C# interface terms, that's a
different method, because COM interop interfaces have to duplicate inherited
methods.

This needs testing to figure out exactly why .NET Framework accepts this.
