accessing Observable extensions from Fsharpx

[nicolas]

If I add FSharpx.Core v1.49, 

#r @"C:\Users\e021230\Documents\Visual Studio 11\Projects\divsharp\packages\FSharpx.TypeProviders.1.5.4\Lib\FSharpx.Core.dll"

I can't 

open FSharp.Control

which seems to contain all the observable extensions.

Yet a bit of reflector shows that the namespace exists in the DLL.

I can open 

FSharpx.IO

FSharpx

But oddly enough, not  FSharp.Control

Could you tell me what I am missing here ?

Thank you

More specific questions :

- Should it work that way

#r @"C:\Users\e021230\Documents\Visual Studio 11\Projects\divsharp\packages\FSharpx.TypeProviders.1.5.4\Lib\FSharpx.Core.dll"

open FSharp.Control

- If not, how do you access Observable extensions ?

My fault : I was referencing the FSharpx.Core from the last successful compile of FSharpx,Typeproviders, which was I believe before a merge that included Observable into Core.
