I generally learn most from these when you have some code examples to go along with the discussion. It's very difficult to understand the examples without any reference. Consider doing another video with the various code scenarios Rich has provided (there are many!).

@@AdamsTaiwan I had just went through the video and was going to mentioned it. The presentation by Matt is excellent!

Amazing stuff! This is the kind of topic you have to watch and re-watch a few times to grasp very well. I have read the blog post previously and the video helped a lot to understand some grey areas that I haven't understand properly. The video probably would be 1h long or more to talk through everything. Thanks again!

This is exactly what I needed haha, thanks for the great content as always!

I subscribed! Nice video and very informative

Hi, Can you guys do a comparative analysis on Memory and T [ ] ?

How can the data be already there without a cache? If I make the same httpcall twice, the call will be async both times, will it not?

Would like to see more examples. I have an app that takes a snapshot of folders/files(with hash codes) on an external drive, saves it to a DataSet then saves it to file or DB. To update I have 2 passes , first pass looks for files in the dataset that have been removed. Second pass checks file system for new or modified files. When I don't have access to the external drive, I can load the DataSet and perform searches or check to see if a set of files on my local drive exist in the DataSet. I'm looking for ways to speed up the process wherever I can.

Oh I get it, so ValueTask means value/vask, not a value (type) task :\ I was damn confused about this name for a while

I don't understand, why provide an Async method that returns ValueTask if you know it's always going to return Synchronously? Why not just use a synchronous method instead.

Imagine your ValueTask is run 99% sync and 1% async. for example you read a file once and after that others use it synchronously, you may not want to block your thread for that 1% time.

Multi Value Tasks.

That blog post did not consider all edge cases (e.g. `Task.WaitAny/WaitAll`, unknown `IValueTaskSource` implementation). And even with it's narrow analysis, conclusion is lame "always use, even when breaking API, but don't await twice". I'm sure Stephen Toub who wrote most of the TPL and `ValueTask` knows a bit more about the topic.
