IAsyncDisposable support?

[Arshia001]

Are there any plans to support the new IAsyncDisposable?

Yes! The second the compiler supports it :)

In a CE we're reliant on methods per language construct (For/While/Using/etc) of which the compiler only recognizes a few signatures, today the compiler does not recognize IAsyncDisposable as a Using overload. There are some discussions to add support for it though

Here fsharp/fslang-suggestions#866
and here fsharp/fslang-suggestions#853

I'll close this out for now.

Yes, I'm familiar with how CE's work. However, I don't believe you need language support for IAsyncDisposables. A let! or match! operates on a M<'a> and unwraps the 'a which, in this case, is a task that must be awaited to get the 'a inside. In the case of IAsyncDisposable, the result is available at assignment time and there is no waiting involved. The waiting must happen within the finally function in a tryFinally. This is quite possible to achieve without language support I believe (though the code will be somewhat convoluted). There's already an example of how to do this at fsharp/fslang-suggestions#866.
