Nuget Package Microsoft.Windows.CppWinRT needed to build solution
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.
Thanks for sharing!

After this, still have error posted.
I found someone who fixed it: https://github.com/FeuFeve/BleWinrtDll/commit/7a6ba261ec807325c7eee124a609aaba4e377802
If someone uses the fix, feel free to create a pull request. The commit above has some other changes that may need to go to the .gitignore?
