.NET 10 announcement<\/a> says .NET 10 is supported for three years, until 2028-11-10, and recommends production applications upgrade to take advantage of the support window, performance improvements, and new capabilities. It also notes that .NET 8 and .NET 9 both reach end of support on 2026-11-10, which makes the planning angle more concrete.<\/p>\nThe developer-facing improvements are still useful. The .NET 10 SDK includes better dotnet test<\/code> support through Microsoft.Testing.Platform, native shell completion, container image support for console apps without Dockerfiles, one-shot tool execution, machine-readable CLI schema output, and dependency auditing by default for .NET 10 projects. Those are not headline-grabbing features, but they improve everyday development and CI.<\/p>\nFor C# teams, I would treat .NET 10 as a housekeeping release with real upside. Upgrade the SDK, check dependencies, run the test suite, look at deployment images, and decide which C# 14 features are worth adopting. The mistake would be treating the language version as the whole story. The platform support window is the main reason this one matters.<\/p>\n","protected":false},"excerpt":{"rendered":"
