Easily create VST3 audio plugins in C#
AudioPlugSharp provides a C++/CLI bridge to load managed audio plugins into VST hosts. User interfaces can be created with built-in support for WPF. Windows Forms interfaces are also possible.
Framework support is .NET Core only. By default, it is configured to use .NET 6.0.
See the SimpleExample and WPFExample projects for example usage.
The current binary release is 0.2. If you just want to build a plugin, you can download this rather than building from source.
Your plugin project will need an assembly dependency on AudioPlugSharp.dll (and AudioPlugSharpWPF.dll if you are using it).
For deployment, you need to copy "AudioPlugSharpVst.vst3" to your output folder, and rename it to be "YourPluginDllNameBridge.vst3". So if your plugin dll is called "MyPlugin.dll", then you would rename "AudioPlugSharpVst.vst3" to "MyPluginBridge.vst3". You also need to copy "AudioPlugSharpVst.runtimeconfig.json" (or "wpf.runtimeconfig.json" if you are using WPF in your plugin) to your output folder as "YourPluginDllNameBridge.runtimeconfig.json". You also need to copy "Ijwhost.dll" to your output folder.
These steps can be done using a Post-build event. Have a look at the included sample plugins for examples - keep in mind you may need to change the source folder of the "copy" commands depending on where your copy of AudioPlugSharp is.
For an example of how to create your own plugin in its own solution, have a look at the LiveSpice VST plugin here:

You will need to have CMake (https://cmake.org) installed.
From a shell, run the following:
git clone --recursive https://github.com/mikeoliphant/AudioPlugSharp
cd AudioPlugSharp
mkdir vstbuild
cd vstbuild
cmake.exe -G "Visual Studio 16 2019" -A x64 ../vst3sdkThen you can load the solution in Visual Studio and build.
