For example, instead of using DbContext.SaveChanges, which will block a thread while database I/O is performed, DbContext.SaveChangesAsync can be used: For more information, see the general C# asynchronous programming docs.
How to execute a LINQ asynchronously in EF Core?

The .Result property waits for a Task to complete, and then returns its result, which at first seems really useful. We can use it like this:
