I cannot configure a working ODBC connection string for SQLite in aspsettings.json for .NET CORE Razor Pages

I have a Visual Studio 2017 .NET 2.2 Core Razor Pages project I have downloaded and installed the ODBC sqlite3 driver. I can see my sqlite database in Visual Studio Server Explorer and I can open tables and see rows. But for the life of me I cannot create a connection string that works.

I keep getting an error when clicking on the link to the page I want to display: "Course table not found". The error happens on the OnGetAsync :

namespace OESAC.Pages.Courses { public class IndexModel : PageModel { private readonly OESAC.Data.MyDbContext _context;

    public IndexModel(OESAC.Data.MyDbContext context)
    {
        _context = context;
    }

    public IList<CoursesViewModel> CoursesVM { get;set; }

    public async Task OnGetAsync()
    {
        //CoursesVM = await _context.Courses.ToListAsync();
        CoursesVM = await _context.Courses
            .Select(p => new CoursesViewModel
            {
                OESACID = p.OESACID,
                CourseTitle = p.CourseTitle,
                Instructor = p.Instructor,
                Locations = p.Locations,

Microsoft.Data.Sqlite.SqliteException (0x80004005): SQLite Error 1: 'no such table: Courses'. at Microsoft.Data.Sqlite.SqliteException.ThrowExceptionForRC(Int32 rc, sqlite3 db) at Microsoft.Data.Sqlite.SqliteCommand.PrepareAndEnumerateStatements(Stopwatch timer)+MoveNext() at Microsoft.Data.Sqlite.SqliteCommand.ExecuteReader(CommandBehavior behavior) at Microsoft.Data.Sqlite.SqliteCommand.ExecuteReaderAsync(CommandBehavior behavior, CancellationToken cancellationToken) at Microsoft.Data.Sqlite.SqliteCommand.ExecuteDbDataReaderAsync(CommandBehavior behavior, CancellationToken cancellationToken)

It happens no matter how I configure the ConnectionString in aspsetting.json.

I have tried every way I could find. Including just a plain path, a relative path, the string I can get when looking at the Connection I configured in VS that lets me see the tables and data. This is the connection string it gives me when configuring the ODBC driver for Sqlite:

"DefaultConnection": "Dsn=SQLite3 Datasource;database=J:\OESAC\Data\sqlite\oesac_new.db;stepapi=0;syncpragma=NORMAL;notxn=0;timeout=100000;shortnames=0;longnames=0;nocreat=1;nowchar=0;fksupport=0;oemcp=0;bigint=0;jdconv=0"

Here is a skinnier version I tried from this website (connectionstrings.com).

"DefaultConnection": "DRIVER=SQLite3 ODBC Driver;Database=J:\\OESAC\\Data\\oesac_new.db;LongNames=0;Timeout=1000;NoTXN=0;SyncPragma=NORMAL;StepAPI=0;"
