I am working on a UWP app and I can't find the async API mentioned here. https://github.com/praeclarum/sqlite-net#asynchronous-api
I have installed only the sqlite-net-pcl 1.5.231 nuget. (https://www.nuget.org/packages/sqlite-net-pcl) Am I missing anything?
With my tests, there's no problem. I can call the async APIs. Please check if you add the SQLite.cs and SQLiteAsync.cs to your project like the Source Installation mentioned.
By the way, you could follow the official document Use a SQLite database in a UWP app to use sqlite database in your UWP app.
