by Jonathan Allen Follow 56 Followers on  Apr 11, 2017

Visual Basic 15 brings with it partial implementations of two important C# features: tuples and ref returns. Neither feature is “complete”, but they do offer enough work-arounds that VB applications can consume C# libraries that make use of these features.
