C# 7.3 Features : Tuple Comparison & Generic Constraints

C# 7.3 is another minor roll-out that brings along with ‘seemingly minor’ improvement, but ones that definitely opens new opportunities. In this blog post, we will explore  two features that are introduced in 7.3

Tuple Comparison

C# 7.x had already made tuple an immensely powerful tool with a variety of features, and the latest minor roll-out takes that a step higher. Prior to C# 7.3, we could not use ‘==’ and ‘!=’ operators to compare tuples. C# 7.3 improvements makes it possible for us to do the same.
var tuple1 = (3,4);
var tuple2 = (5,6);

if(tuple1 == tuple2)
// Do something

Generic Constraints

The way I see it, this might turn out one feature which find more fans.  Generics, since its introduction in C# 2.0, was always handicapped by its in ability to constraint the accepted generic type must be an enum.
void TestMethod(TSource param) where TSource : Enum
// Do something
C# 7.3 also allows you use following constraints
  • unmanaged
  • delegate
That’s it for now, we will explore more features soon.
