I still can't believe that this kind of knowledge is available for free.

How does the Mediator pattern play together with Domain Events? I'm a bit confused.

[@gorangratte2471]

At 1:23 the handler is in the Services namespace. Is that intended or should it be a separate namespace for handlers?

[@richardhight4430]

NullReferenceException is perfectly fine as long as you construct it with a message that specifically says "x cannot be null". If there is no message as such then the developer is to blame for the oversight.

[@nagrotte]

Object reference is not set to an instance of an object - lol

[@johnnycagebringbackdislike9806]

If you instead opt for custom exception, you can handle it in global exception handler to return 404 instead of ambiguous 500. Call it "ResourceNotFoundException" that gets string name of the resource and the ID client used - simple and clean.

good

[@indianfootball2328]

does any one have link to the video: solution to the solution problem mvc5? it was on channel 9 but cant find it now

[@fabriziopastor6146]

Is the code on github?

[@johnnycagebringbackdislike9806]

MediatR has a pretty major downside when it comes to readability and handling errors. Try to read and understand what is going on in the system - sooo much clicking and text search while you could just CTRL+Click few times. And it is not atomic. If you mutate entities in single data source - you'd have a hard time adding extra safety layer to rollback stuff.

so far i'm with you Jonny Cage...MediaR / CQRS really destroys the simple beauty of CRUD for me. Trying my best to totally grasp it still.

Pluralsight course, it is not free anymore
