+The `RelationalExtensions` packages support EF Core 8, 9, and 10 but do not ship a `net11.0` target: EF Core 11 removed the `QuerySqlGenerator` fallback that renders third-party SQL expressions ([dotnet/efcore#37533](https://github.com/dotnet/efcore/pull/37533)), with no replacement extension point.

Applications on .NET 11 that need window functions should stay on EF Core 10, which runs fine on the .NET 11 runtime. Note that NuGet will not block installing the package in a `net11.0` project — it silently falls back to the `net10.0` build, and window functions then fail at runtime with EF Core 11's `Unhandled expression … in 'QuerySqlGenerator'` error.
