Alongside Metalama 2026.0, we’re announcing the general availability of PostSharp 2026.0. This release brings full support for .NET 10 and C# 14, including proper handling of the new extension blocks syntax introduced in C# 14.
Metalama 2026.0 is now generally available! This major release brings full support for C# 14—the most significant evolution of the C# language in years—along with .NET 10 SDK and Visual Studio 2026 compatibility. We’re also closing one of the last feature gaps with PostSharp: the ability to override event handler invocations. And you’re getting first-class support for tuple types.
Metalama 2026.0 has reached Release Candidate status! All planned features are implemented, our test suite is green, and the release is stable enough for production evaluation. We’re now gathering community feedback ahead of our GA release on January 5th, 2026.
October is traditionally our busiest month. Microsoft ships the RCs of the .NET SDK, C# and Visual Studio, and we sprint to make Metalama ready. This year is no exception: we’ve made solid progress, and we’re confident we’ll be ready on time for the GA wave. Below is a recap of what we shipped and what’s coming.
Welcome to Metalama’s September 2025 status update. After a relaxed summer, we’re back in full swing, delivering .NET 10 SDK support for Metalama and closing a key gap versus PostSharp: the ability to override event handler invocations.
