HTTP-Push (Comet/Reverse Ajax) 使用 Silverlight 到 Javascript 桥? [英] HTTP-Push (Comet/Reverse Ajax)using Silverlight to Javascript bridge?

问题描述

使用 PollingDuplexHttpBinding 与 Silverlight 结合 RegisterScriptableObject 函数 实现 Comet 风格的 javascript 功能?
(参见教程)

我从未在论坛中看到过这种方法的讨论，也从未将这种方法推荐为免费解决方案.相反，只听说过付费选项，例如 WebSync 和 PokeIn.

Silverlight 是否实现了Bayeux 协议?应该吗?

解决方案

您会遇到一些严重的可扩展性问题，而且实施起来非常痛苦.见:

如果您想在 Silverlight 中实现 Bayeux，则需要 WebSync.

Is it a good idea to use PollingDuplexHttpBinding with Silverlight in conjunction with the function RegisterScriptableObject to achieve Comet-style javascript functionality?
(see tutorial)

I have never seen this approach discussed in the forums, or recommended as a free solution. Instead only heard about paid options such as WebSync and PokeIn.

Does Silverlight implement the the Bayeux protocol? Should it?

解决方案

You'll have some serious scalability problems, and it's a royal pain to implement. See:

If you want a Bayeux implementation in Silverlight, you want WebSync.
