EnumerableEx.Merge - Missing

Question

Hi,

Why is EnumerableEx.Merge no longer included in the latest Rx release?  What is the recommended replacement that we should use?

Thanks,
Dave

Answer 1

Hi,

I'm using SelectMany instead of Merge and it seems to be working fine.

Answer 2

Hi Dave,

For some reason the Rx team have gone off the idea of interactive extensions that introduce multi-threading.

Latest release notes;

"Removed Amb & Merge from System.Interactive in favor of ToObservable.Amb using System.Reactive"

Enumerable.Range(1,100).Merge(Enumerable.Range(101,100))
~=
Enumerable.Range(1,100).ToObservable().Merge(Enumerable.Range(101,100).ToObservable()).ToEnumerable()


Maybe someone from the team can shed some light on this.

Answer 3

Thanks James, I didn't notice that in the release notes.

Answer 4

It is just as easy to convert to and from Observable and use Merge or Amb.

 

Without creating a cyclic dependency between System.Reactive and System.Interactive, it meant that we had to implement all async code manually in System.Interactive which lead to code bloat and duplication.
