Description

If you want to force the dbContext to make a new db call instead of relying on its identity map, you can do so with this approach:

dbContext.ChangeTracker.QueryTrackingBehavior = QueryTrackingBehavior.NoTracking;
var fromDb = await dbContext. [whatever query]
dbContext.ChangeTracker.QueryTrackingBehavior = QueryTrackingBehavior.TrackAll;

Create extension methods that simply turn off tracking and then turn it back on that require less code than assigning to the QueryTrackingBehavior does.

Contributor guide

Research direction
Create extension methods on DbContext to wrap QueryTrackingBehavior assignment: one method to disable tracking and one to re enable. Look at existing EF Core extension patterns.
