.NET 5 and pooling for ValueTasks

.NET 5 is around the corner and it will bring a lot of goodness to the land of performance. One of the interesting aspects that I visited when working on Async Expert online course is the aspect of pooling boxes hidden behind ValueTask returning operations. The reasoning behind it can be found in the awesome article Async ValueTask Pooling in .NET 5 authored by Stephen Toub. This post focuses on diving deep in the codebase and seeing how it’s implemented behind it.
