An exploration of .NET 7 trimming on a various simple apps including a TODO app using ASP.NET Core and Entity Framework Core.
Read more about trimming in .NET apps in the official docs.
This solution currently uses a daily .NET 7 SDK main build (see exact min-version required in the global.json). You can grab such a build from the installer repo.
From the repo root, run one of the PowerShell scripts to publish and run the various apps.

- Results taken on Windows 11 x64
- All apps are published using "Release" configuration
- Only trimming modes that result in the app still working are shown
- Execution time measures time for the app to run (startup, execute, close). Web apps are configured to send a request to themselves on startup and then shut themselves down when being measured.
