Create Database on Runtime - Entity FrameWork Code-First-CodePudding

I have a project which saves its output results into an SQLite database. in every run, the user should select the saving location which the program will create a database there and will save the result inside. so the database's name and location are dynamic.

How can I manage such a thing using entity framework core code first? I have create the models and the DbContext class, but I do not know how to create the database and tables on runtime and so on.

I have found the solution, I should use raw.SetProvider(new SQLite3Provider_e_sqlite3()); in OnConfiguring:

public MyDataContext(string path, bool create = true)
{
    FilePath = path;
    if (create)
    {
        Database.EnsureDeleted();
        Database.EnsureCreated();
    }
}

protected override void OnConfiguring(DbContextOptionsBuilder optionbuilder)
{
    optionbuilder.UseSqlite($"Data Source={FilePath}");
    raw.SetProvider(new SQLite3Provider_e_sqlite3());
}
