Is keyed DI something you've been crying out for? Or does it just complicate things? Leave a comment.

I use keyed DI in Autofac, very useful.

Hi there, thanks for the tutorial on this new feature for .NET 8. Although a potentially useful feature, I'm not a big fan of injecting IServiceProvider. Would it not be nicer if instead you could inject a dictionary of the key and object type?

Hi, i was looking for some kind of course to explain the fundamentals of threading in .NET, but it seems all I can find is focused on async/await, or it's not really good quality.

Could you consider making a video about threading concepts and how to manage them with .NET (not just .NET Core)? I'm looking for explanations about types of threads, stack vs heap, race conditions, synchronization, deadlocks, thread pools, different ways to create threads, UI threads and dispatchers, App domains etc... there is potentially a lot to cover

Nice!!!
(But way too much advanced for me)

Why call it DEPENDENCY INJECTION? What’s wrong with calling it Method Parameter …. simple English?
