The endjin team has released Rx.NET 7.0 (the `System.Reactive` 7.0.0 package on NuGet). The key change resolves a long-standing assembly "bloat" problem: previously, adding an Rx.NET reference in self-contained apps with Windows target frameworks pulled in WPF and Windows Forms, inflating output by roughly 90MB (47MB with trimming, 11MB for NativeAOT). UI framework functionality now lives in separate packages — `System.Reactive.Windows.Forms`, `System.Reactive.Wpf`, `System.Reactive.WindowsRuntime`, and `System.Reactive.Uwp`. Support for .NET 7.0 and earlier has been dropped; target platforms are .NET 8, 9, 10, .NET Framework 4.7.2, and UWP. The release wraps up the technical-debt cleanup, clearing the way for performance improvements and new operators.
