Can't use source file SQLite.cs in a lib

Hi,

I have a Xamarin solution and inside it I created a netstandard 2 lib for managing database stuff using sqlite-net-pcl lib.

I'm trying to use last version of SQLite.cs because I wanted to test if it solves an issue I reported you in 1.5.231 regarding order async methods but unfortunately it does not work because I'm getting this error:

/Users/endymion/code/hybrid_app/DataStore/Data/WorkItemsDatabase.cs(18,18): Error CS0246: The type or namespace name 'SQLiteAsyncConnection' could not be found (are you missing a using directive or an assembly reference?) (CS0246) (DataStore)

For some reason the compiler can't found SQLiteAsyncConnection although using SQLite is placed in WorkItemsDatabase.cs

By the way I tried the same in a Console app project and it works fine so I'm a bit confused.

My environment:

IDE: Visual Studio Code for Mac
MacOS: 10.13.6
Lib C# version: 7.3

Start with the reported WorkItemsDatabase.cs usage and compare the netstandard library project with the Console app, focusing on how SQLite.cs and the SQLite namespace are referenced. Reproduce the CS0246 error with SQLiteAsyncConnection; done means identifying the project-reference or compatibility difference and confirming that the type resolves in the library.
