@adamkimberley2575 3 года назад

Great tutorial. Thanks.

@gajarubanjeyakumar7226 3 года назад

Thanks, Ben. I hope in the future, you will do a complete project in F# on youtube.

@bengobeil933 3 года назад

You are in luck. Stay tuned.

@gajarubanjeyakumar7226 3 года назад

@@bengobeil933 Looking forward to it.

Hello, Ben, now that F# has task support, will you consider uploading a new video? Your videos helped me a lot so thank you!

Can you make a F# tutorial for Avalonia UI

@rickdeckard1075 3 года назад

any thoughts on observables? there was an "AwaitObservable" extension that petricek talked about but i never saw what became of it

@bengobeil933 3 года назад

Hmm I will look into it

@bainewedlock1274 3 года назад

Quick question: It seems that async { do printfn "1" } behaves just like async { printfn "1" } Is there a difference?

@bengobeil933 3 года назад

I don't believe there is a difference in this context. For some computation expressions, you might have specify "do" for it not to be conflated with data that you want to yield in your expression.

IMHO: Concurrent - sharing the same resource in (managed) order Parallel - using multiple resources at the same time

So if I want to start something and await it asynchronously I can do it only inside async CE using bangs ?

@bengobeil933 2 года назад

If you want to start something and await it, you can Async.StartAsTask and await either using the Task computation expression (using the library Ply, or coming native to F# soon), or use Async.AwaitTask. task computation expression is practical if you are often doing these styles of computation

@@bengobeil933 Ok, and if I want to unwrap result from Async the only way is async CE ?

@bengobeil933 2 года назад

@@10199able Most of the time yes, but it depends on what you want to do. Their are Async library functions that might suit what you want to do. Most of the time, for enhanced readability, you will be using either Task or Async computation expressions. You might use Async.RunSynchronously for example to unwrap the value, which wouldn't require a CE, but will do so in a sync fashion.
