+For game developers using C#, you can now use .NET 8 as a target framework for your Amazon GameLift Servers projects. With .NET 8, you can take advantage of performance improvements, including improved just-in-time (JIT) compilation, memory usage optimization, and faster startup times. If you're currently using .NET 6, we recommend that you plan a migration to .NET 8, including updating your C# server SDK to the latest version. Microsoft announced .NET 8 support, with security patches and technical updates, through November 2026.
