I've just installed the newest Release (v1.1.10425) of Rx for Silverlight 4 and 5 (Beta). I've seen that the package is missing 3 DLLs I've used in my projects in the past:
System.CoreEx.dll
System.Interactive.dll
System.Observable.dll
What I'm actually missing is the following extension method:
System.Linq.EnumerableEx.Run<TSource>(this System.Collections.Generic.IEnumerable<TSource>)
Where has it moved to? Was it merged with an other assembly?
This doesn't exist in the latest release, sorry. You can still use the System.Interactive from a previous release though.
Update: This is now a NuGet package
Update 2: There is now a non experimental NuGet package, as well as non experimental Ix-Async
