Why Async.Start' ?

[OnurGumus]

I am seeing this code:

static member Start' (computation:Async<unit>, ?cancellationToken: CancellationToken) : unit =
            #if FABLE_COMPILER
                Async.StartImmediate (computation, ?cancellationToken=cancellationToken)
            #else
                Async.Start (computation, ?cancellationToken=cancellationToken)
            #endif

But in fable Start and StartImmediate are the same thing.

Yes, but AsyncRx can be used outside of Fable. Sometimes we want to use Start and not StartImmediate for .NET environments. That could would then trigger a warning with Fable. This is to get rid of that warning.

FYI: fable-compiler/Fable#1826

btw there is a plugin for webpack which allows you to suppress warnings by text matching.
