Are there any updates?
Is it possible to persist a couple of cosmos documents in one transaction using EF Core Cosmos provider?

@vyarymovych this issue is in the backlog, which means it's not currently in the plan for EF Core 7.0 - please vote (:+1:) for it on the top comment, that helps us prioritize work.

My feedback is that such a basic database feature, transactions, should not be in a backlog but planned for EF Core 7.0. Please reconsider. We can't use EF Core 7.0 on our projects without this capability.

We need this feature as well. The only way forward is to do state changes in our application with the CosmosClient with batches. Possibly use EF core to write queries, so we can leverage LINQ.
