Adding the SQLite NuGet package

To access SQLite in this project, we need to add a NuGet package called sqlite-net-pcl to the .NET Standard library project. To do this, right-click on the Dependencies item under the DoToo project node of the Solution and click Manage NuGet Packages:

You might notice that the NuGet package is suffixed with -pcl. This is an example of what happens when naming conventions go wrong. This package actually supports .NET Standard 1.0, even though the name says Portable Class Library ( PCL), which was the predecessor to .NET Standard.

This brings up the NuGet Package Manager:

Click Browse and enter sqlite-net-pcl in the search box
Select the package by Frank A. Krueger and click Install

Wait for the installation to complete. We'll then add some code to the TodoItem class and the repository.
