GetItemsAsync 使用 .Net MAUI 不返回任何项目

Question

I have migrated some code from the old Azure Mobile Client to DataSync, and the GetItemsAsync method is returning 0 items, although there are items in the database.

Here is the code snippet public async Task<IEnumerable<Configuration>> GetItemsAsync() { await InitializeAsync(); return await _table.GetAsyncItems().ToListAsync(); } public async Task<IEnumerable<Configuration>> GetItemsAsync() { await InitializeAsync(); return await _table.GetAsyncItems().ToListAsync(); }

If I execute the exact same command through the web portal the correct result is returned.

I am expecting the GetAsyncItems to return a list of items (as it did previous using the Mobile Service Client package).

The call returns a list of 0 items.

If I examine the http traffic, the correct request is sent to Azure and the correct response is returned.

Based on your final comment, you are using the client that uses the v3.0.0 ZUMO-API-VERSION and you are using the v2.0.0 ZUMO-API-VERSION backend. I'm surprised it is working at all.

When thinking about the ZUMO-API-VERSION

2.0.0 client works with either a 2.0.0 or 3.0.0 server. 3.0.0 client ONLY works with a 3.0.0 server.

So you can update the server, then update the clients, but not the other way round.
