Confirming the various ways of doing C#'s default(T) in VB are all equivalent.
Methods tested [using simple Debug.Assert on a command line app]:
Public Function GetDefaultDeclaration(Of T)() As T
Dim result As T = Nothing
Return result
End Function
Public Function GetDefaultNothingDirect(Of T)() As T
Return Nothing
End Function
Public Function GetDefaultNothingCtype(Of T)() As T
Return CType(Nothing, T)
End Function
Public Function GetDefaultNothingDirectCast(Of T)() As T
Return DirectCast(Nothing, T)
End Function
Method not tested:
Return New T() ' Not equivalent to default(T) at all and only works for reference types.
