* Sample and tool apps now roll forward onto newer .NET runtimes, so running them no longer requires the .NET 9 runtime to be installed * Fixed the `NAudio` and `NAudio.Extras` meta-packages resolving their portable `net9.0` asset on projects targeting a plain `netX.0-windows` TFM (the WinForms/WPF template default), which silently dropped the entire Windows stack — no `WaveOut`, WASAPI, Media Foundation, ASIO, DMO or WinForms types, and `AudioFileReader` throwing "MP3 file reading requires the NAudio.Wasapi package". Both packages now also ship a plain `net9.0-windows` leg (#1407) * **Breaking:** `AudioFileReader` now throws `NotSupportedException` instead of `InvalidOperationException` when the cross-platform build is asked for a format it cannot read, and the messages simply state that rather than suggesting an `NAudio.Wasapi` install that could never have helped (#1407) * Projects on a plain `netX.0-windows` TFM may now see `CA1416` warnings when calling WASAPI process-loopback capture. The warning is correct — those callers do need an `OperatingSystem.IsWindowsVersionAtLeast(10, 0, 19041)` guard — and was previously hidden because the only Windows asset available already implied that floor (#1407) * Fixed `AiffFileReader` reporting too long a `Length` and throwing `IndexOutOfRangeException` when the SSND chunk declares a non-zero offset (#1405) * Fixed `AiffFileReader.Read` throwing `IndexOutOfRangeException` when the source stream returns fewer bytes than requested (#1405)
