Xamarin.Forms Sqlite-net NotSupportedException on ManyToOne relationship “Don't know about ”

Question

I am using sqlite net extensions library in my xamarin.forms application. I code in my PCL the database code and models.

When I call SQLiteConnection.CreateTable() I get

Answer 1

The problem was that I had installed two different libraries for sqlite, both containing a SQLiteConnection.

I needed to use the Sqlite.Net.SQLiteConnection class for sqlite net extensions. Not the Sqlite.SQLiteConnection I was using.

As SushiHangover pointed out, this Sqlite.Net.SQLiteConnection takes a first argument of type ISQLitePlatform.

To obtain a reference for this, I defined an interface that provides the signature of a method to return a ISQLitePlatform:

public interface ISQLitePlatformInstance
{
    ISQLitePlatform GetSQLitePlatformInstance();
}

And I implemented the interface in my Droid project ( the platform I'm building against):

public class SQLitePlatformInstance : ISQLitePlatformInstance
{

    public ISQLitePlatform GetSQLitePlatformInstance()
    {
        return new SQLitePlatformAndroid();
    }

}
