How to Configure a Download-Only Table in Dotmim.Sync?

[herczegzoltan]

I have successfully synced multiple tables, but I need one specific table to be download-only. I looked at the sample project, but it appears to be empty.

https://github.com/Mimetis/Dotmim.Sync/blob/master/Samples/SqliteDownloadOnlySyncProvider/SqliteDownloadOnlySyncProvider.cs

Could someone provide an example?

This setup uses a Maui + Web API. Here's what I did on the client side:

var setup = new SyncSetup("TestTable1", "TestTable2");
setup.Tables["TestTable2"].SyncDirection = SyncDirection.DownloadOnly;
var agent = new SyncAgent(clientProvider, serverOrchestrator, options);
var progress = new SynchronousProgress<ProgressArgs>(args => Console.WriteLine($"{args.ProgressPercentage:p}:\t{args.Message}"));

I removed all migrations and deleted the existing tables on the server. Then, I added a new migration, and all tables were successfully created.

After cleaning the database on the client and running the app, the sync method throws the following exception:

Dotmim.Sync.SyncException: Seems you are trying another Setup than what is stored in your server scope database. 
You have already made a sync with a setup that has been stored in the server.

What am I doing wrong?

Try a new scope name

Do you mean the download only tables needs different scope than the others?
like this:

Just because before I removed everything client local database file, server database and close all connection also got rid of the migrations. To start fresh and when I start the app it creates the tables but the above error is thrown.

The problem is that you have changed your SyncSetup (by adding SyncDirection.DownloadOnly to one table) after having made some syncs.
That's why you have this error.

If you are in testing mode, I suggest to start from scratch each time you are changing your setup
You can start with a fresh backup from you database without any DMS related metadata
Or you can call a DropAllAsync() method to remove everything from DMS in your database, and start with a new setup
