But Let's say you'll want to be certain don't just that the filters get the job done, but they’re appropriately put in place and applied to personal action techniques? What in order to refactor some API code you already have to make the most of the filters I just confirmed, and you should make certain the API nevertheless behaves appropriately when you’re concluded?

It isn't reinventing the wheel. Several of the extensions have by now been recommended. You may rewrite your logic as follows.
Filters: The execution order for filters is decided based on the sort of filters that you are making use of for the controllers and motion procedures. So, the buy of Filters is just not essential.
Up coming, we have to sign-up the Logger Assistance into your constructed-in dependency injection container.
