Reactive Extensions in a Workbook

AntaoAlmada

I added the rx-main package to the a WPF Workbook but when I type 'using System.Reactive;', both the autocompletion and the compiler fail to find the namespace. I tried my own NuGet package and worked fine.
What am I missing here? What version of .NET is the WPF Workbook using?

AntaoAlmada

Any idea why it doesn't work?

Thank you for filing a bug so that this is on our radar.

There are a lot of NuGet packages that don't work correctly yet. See https://developer.xamarin.com/releases/inspector/preview/inspector-0.8.1/#KNOWN_ISSUES.

Thanks for the reply. Just wanted to contribute with a test scenario and to be sure RxNET was under your radar.

Still doesn't work in 0.9.0

Today a new version of Rx.NET was released supporting .NET Core 1.0. It requires NuGet 2.12 while version supported by 0.9.0 is 2.10.766.
The package is now called System.Reactive 3.0.0.

I tested version 1.0.0.0 released today and I'm happy to say that it can finally add System.Reactive.* packages.

Unfortunately when I run:

#r "System.Reactive.Linq"
using System.Reactive.Linq;
Observable.Interval(TimeSpan.FromSeconds(1)).Take(10);

I get the following message and nothing happens.

"warning CS4014: Because this call is not awaited, execution of the current method continues before the call is completed. Consider applying the 'await' operator to the result of the call."

If I await the observable, I get only the last value. This is the expected behavior for an awaited observable but it would be interesting to not have to await and see all the returned values, just like LinqPad has been doing for a long time.

I got some help from Paul Betts that gave me this solution:

#r "System.Reactive.Linq"
using System.Reactive.Linq;
await Observable.Interval(TimeSpan.FromSeconds(1)).Take(10).ToList();

It shows all the values once the observable completes. It works but it would be much nicer if you supported output from IObservable and show the values as they become available.

SandyArmstrong

Glad it works! IObservable support would certainly be a useful feature.

Any news on this? Has IObservable() support been added to any of the recent versions ?
