Now that you're using the Lazy class in C# to handle lazy initialization the dotnet way, you're encountering situations where you want to use async await with it. But does the Lazy class support asynchronous operations? And if it does... should we be using it? Let's find out.

I just started and playing with LAZY and then I was like uh oh, how can I make this work with an async Task & boom so glad I bump into this magnificent well put tutorial, giving it a go right now as I'm watching this!!!! SUBSCRIBED 🔥🔥

Hahaha! That's so awesome to hear 😂 Well thanks for giving my channel a chance! Please feel free to request other topics as you're venturing along! Just drop a comment on a video and I'll see if I can whip something up 🙂

That might be a stupid question but what are the advantages of putting a Task in a Lazy instead of just using a Lazy ? Also: that’s why you always read error messages :)

@DevLeader 11 месяцев назад

No stupid questions! It's a safe place 🙂 Personally, for me it's just limited to the benefit of running code in an async await paradigm. If the stuff I want to perform in my lazy method has already been designed for async await, then I can still call it without redesigning things. Yes - we could do things like .Wait() or .Result without using a Task, but those generally are more prone to problems I've found. So TL;DR - if I have async/await code and I want to do an operation once to lazy load something, that's when this fits nicely (just need to be careful for exceptional cases).

How I went through a whole .NET bootcamp without ever hearing this, is beyond me!

@DevLeader Год назад

I try not to be too harsh on bootcamps but I think the majority are just designed to convince you of some expertise in a short time frame ☹️ Hopefully my free content can be helpful to fill some of the gaps for you though! Thanks for the comment 🙂

I like your channel. Somehow I have a feeling you are spending a bit too much time explaining the obvious. I assume most people know what is await, and if they didn't - this video will not explain it although you are going back on it several times. Nevertheless, thumbs up for the channel!

Great feedback - One of the things I'm paying attention to even outside of video creation is over explaining or explaining the obvious. This is rooted in trying to ensure that I'm able to demonstrate my knowledge to someone. My "defense mechanism" (if I can call it that) is to just keep explaining until I've exhausted how I think I can articulate something. I've been told it's actually helpful in some scenarios (mostly very new folks) but otherwise it's a detriment. So I'm trying my best to improve 🙂 Thanks!
