+private record ListResult(string id, string name, string owner_id, string created_at);
+
+static async Task Main() {
+
+    // Ensures the DB file is stored in a platform appropriate location
+    var dbPath = Path.Combine(FileSystem.AppDataDirectory, "maui-example.db");
+    var factory = new MAUISQLiteDBOpenFactory(new MDSQLiteOpenFactoryOptions()
+    {
+        DbFilename = dbPath
+    });
+
+    var Db = new PowerSyncDatabase(new PowerSyncDatabaseOptions()
+    {
+        Database = factory, // Supply a factory
+        Schema = AppSchema.PowerSyncSchema,
+    });
+
+    await db.Init();
+
+    var lists = await db.GetAll<ListResult>("select * from lists");
