Example of workspace project please

## Feature Request
I am having a hard time understanding how to put together a multiplatform workspace project and it would be extremely useful to have an simple example project to look through.

The issue does not name a file, test, or entry point. Start by surveying the repository's existing workspace and multiplatform examples, then define the example's supported targets and documentation location; done means a newcomer can inspect it and understand how to assemble a multiplatform workspace project.
