Visual Studio 18.5 introduces official SDK-style project support for VSSDK-based extension (VSIX) projects. The update brings up to 75% build time reduction through incremental build support and Fast Up-To-Date Check, updated in-box templates defaulting to SDK-style, and a more compact csproj format. Existing MPF-style extensions continue to work without forced migration. A migration guide covers key steps including XAML support, solution deployment configuration, and key MSBuild properties. Microsoft is also experimenting with an agentic conversion workflow via the vs-agent-plugins Modernize agent.
