Observable Adapter

Observable Adapter

  • Comments 2

.NET 4.0 introduced a pair of interfaces, IObservable<T> and IObserver<T>, supporting subscriptions to and notifications for push-based sequences. In combination with Reactive Extensions (Rx), these interfaces provide a convenient and uniform way of describing event sources and sinks in .NET. The StreamInsight CTP refresh in November 2009 included an Observable adapter supporting “reactive” event inputs and outputs.

While we continue to believe it enables an important programming model, the Observable adapter was not included in the final (RTM) release of Microsoft StreamInsight 1.0. The release takes a dependency on .NET 3.5 but for timing reasons could not take a dependency on .NET 4.0. Shipping a separate copy of the observable interfaces in StreamInsight – as we did in the CTP refresh – was not a viable option in the RTM release.

Within the next months, we will be shipping another preview of the Observable adapter that targets .NET 4.0. We look forward to gathering your feedback on the new adapter design! We plan to include the Observable adapter implementation into the product in a future release of Microsoft StreamInsight.

  • Hi guys,

    Any news on the Observable Adapter, seeing that it is September now and you wrote about this way back in May? Or have I missed the release ....?

  • Niels,

    No this has not been released yet/ Unfortunately, we can't be any more specific than we were in the article for the time being. But be assured that this is one of our highest priorities to wrap up and ship!

    Regards,

    Roman
