Makes it easy to wrestle with LocalDB.
It's just
var localDb = new LocalDb();
var instance = localDb.GetInstance(instanceName: "MSSQLLocalDB");
instance.CreateIfNotExists();
var database = instance.GetDatabase(databaseName: "test_db");
database.CreateIfNotExists();
var connectionString = database.ConnectionString;
// off you go ๐
and off you go ๐
