Behold the magic of collection literals in the soon-to-be-released .NET 8!

Python users have been flaunting this feature for some time now, envy-inducing for sure. But why the fuss?

Picture the simplicity of creating a collection with: List<int> start = [1, 2, 3];

Pleasing to the eye, wouldn’t you agree?

Apart from being nicer to write, it is also more performant!

How? The compiler will now decide the best way to create the collection.

It might set the initial capacity just right based on how you use the collection or employ other swift tricks for rapid execution.

Wait for it…the real spectacle is yet to unfold. This magic doesn’t just work for explicit types, but interfaces too!

IEnumerable<int> start = [1, 2, 3];

Be it an array, a List, or even a custom implementation, the compiler will cherry-pick the best for you!

Excited for the .NET 8 release next month? Hang tight, the magic of collection literals is on its way!
