Command Interception

[satyajit-behera]

When can we expect the simple command interception to be implemented in EF Core. In its absence, are there any work around of implementation of IsDeleted type of feature in EFCore?

@satyajit-behera we haven't decided if we want to have command interception that looks like the one we did in EF6 but here are a few related things:

• Issue Events and interception (aka lifecycle hooks) #626 covers all lifecycle hooks which could include some means for command or query interception
• We have been thinking a lot about the concept of filtering applied to a model and DbContext, which should make it easier to implement soft-deletes than interception. We are using Model-level Entity Filters #7413 to track that.
• Although it requires using and replacing some of our internal service types, there is already a way to achieve command interception. @ajcvickers could you please point to the test that does this?

Closing as a duplicate of #636 and #7413.

@divega Thanks.
@ajcvickers Please let me know how I can achieve this using a different mechanism. Thanks.

@divega Not sure what you are referring to; I haven't done this in EF Core. I think @anpete might have done something at one point. @satyajit-behera If I was going to start somewhere, I would probably investigate replacing SqlServerConnection, or whatever the RelationalConnection class is for the provider you are targeting.

@ajcvickers ok, I guess I had it mixed up in my notes. @anpete do you know of a test that does service replacement to achieve something similar to command interception? I had this in my notes from triage but it might have been a misunderstanding.
