Information about .NET 11 and C# 15 is starting to flow in

Last November, Microsoft made available .NET 10 and C# language version 14, but already, we are seeing plans for .NET 11 and C# 15 in the public. The Preview 2 has just been made available, and it's interesting to see that it should support an asynchronous runtime, but also require more modern CPUs, similar to those that Windows 11 requires.

In addition to these new features, one of my favorite new features is the support for the Zstandard or Zstd compression algorithm. This support will live in the System.IO.Compression namespace.

With the current schedule, .NET 11 and C# 15 are planned to become available in November 2026, following the yearly cadence already used for many years.
