Using Rx with WCF ?

Question

Hello World

I want to using Rx in my current Silverlight 5 project. I want to load data from WCF Services i did not find any good example for that please let me know how to do that using Rx. I am using 2.0 version of Rx. I have tried FromEvent<> but did not get success.

i found this on net

 IObservable<IEvent<GetCustomersCompletedEventArgs>> observable =
        Observable.FromEvent<GetCustomersCompletedEventArgs>(
            client, "GetCustomersCompleted"
        ).Take(1);
but i did not find IEvent<> in my dlls of Rx. Please let know how to use this kind of Service method not begin and end pattern.

Hi,

Make sure that you reference all of the following DLLs for Silverlight 5.  I recommend using the Rx NuGet Package.

• System.Reactive.Interfaces.dll
• System.Reactive.Core.dll
• System.Reactive.Linq.dll
• System.Reactive.PlatformServices.dll

Then take a look at this discussion:

Hello

Thanks for reply. All i need to call the service method using Rx. I have added all Reference using NuGet  Packages Manager. Can you me give me an example for that. i am unable to find IEvent in dlls

Hi,

You want to use IEventPattern<T>.  I think IEvent<T> was the old name in the original beta releases.
