Good job guys! I am working on a .NET MAUI and a ASP.NET Core project with .NET 8 and loving it! Keep up the great work!

As a software architect focusing on scalability and building high throughput APIs, the latest release is a massive improvement. I don't think the vast majority of the devs out there truly appreciate the work that's gone in the latest v8 release.
