`InvalidOperationException` with hot observable calling `AwaitObservable` from within `Async` #29

Open exercitusvir opened 9 years ago

exercitusvir commented 9 years ago

I just got an InvalidOperationException with the message Async.FromContinuations was invoked multiple time" when using the AwaitObservable that takes only a single IObservable in FSharpx.Async 1.12.0

I found this commit which might be related, but I don't know if it is already in the current nuget package of FSharpx.Async 1.12.0.

I am calling AwaitObservable from within an Async returned by AwaitObservable that is still running. Might this be causing the problem? Are your tests covering that case?

This is fixed by the commit that I referenced. So it just needs to be pulled. The author is already working on getting the tests work on the build server.
