Windows CoreAudio wrapper for .NET
Thanks to @uxsoft there's now a NuGet Package available: https://www.nuget.org/packages/CoreAudio/
Since this project is just a wrapper for the native Win32 API you should be able to follow Microsoft's official C++ documentation: https://docs.microsoft.com/en-us/windows/win32/coreaudio/core-audio-apis-in-windows-vista
You may also refer to the included samples, kindly provided by contributors to this project.
