Cloned project and tried to build according to instructions in Readme.md, however build failed on error "wait_for is not a member of winrt::impl"
Found solution being installing the Nuget Package Microsoft.Windows.CppWinRT,
- Right-click on Refernces in solution window.
- Click manage Nuget packages...
- Click browse tab
- Find Microsoft.Windows.CppWinRT
- Install
After that building worked.
