Anyone wanting to use VS Code for development should see this forum post: Visual Studio for Mac - #20 by jnicol
Inspired by this I created an example plugin that can be built from VS code and debugged in AudioPluginHost.
See: GitHub - ChristopherJohnston/HelloWorldPlugin.
I extended the build tasks slightly to allow selection of a scheme when building by way of a “pickString” input parameter rather than just using the --alltargets flag.
I also added a configuration file for the C/C++ extension (c_cpp_properties.json), which enables intellisense code completion.
See the readme on the git repository for more details.
