説明
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.
