Silverlight Streaming service news

    General discussion

  • Hi all,

    We’ve updated the service last night, mostly with bug fixes. See details below:

    • You can now include more than once on your web page.
    • Values passed into the initParams: field of createHostedObjectEx() are now passed on to the eventual Silverlight invocation. This gives you a way to pass some information from the containing web page to your Silverlight application.
    • White is the new pink. The pink background once visible during application load is now white instead.
    • We no longer support pre-MIX'07 versions of Silverlight. When we launched the Alpha version of Silverlight Streaming at MIX'07, we supported applications that used the February '07 CTP version of Silverlight as well as the Silverlight versions released at MIX'07. Now all end users that view your applications must be using the MIX'07 releases or later. Both Silverlight 1.0 Beta and Silverlight 1.1 Alpha are supported.

  • Hi all,

    We have updated the service last night to allow Silverlight Streaming to support the latest Silverlight RC public release. In order to be compatible with the new release candidate for Silverlight, you will need to make the following changes to how you invoke your Silverlight Streaming applications:

    1/ Include the new silverlight.js from (instead of ".../g/...")

    2/ Call Silverlight.createHostedObjectEx() (instead of Sys.Silverlight.createHostedObjectEx()

    Make no changes to allow your existing applications to continue to run with the 1.0 beta release of Silverlight.

    Please note that while Silverlight Streaming can host both 1.0 beta and 1.0 RC applications, the end user's browser must have the version of Silverlight that matches the application.

  • Hi all,

    There are two cool new feature in the Silverlight Streaming that we were itching to make public. They will simplify the usage of the service on one hand, and make it usable in a broader range of scenarios on the other hand.

    • You can now invoke Silverlight Streaming applications without JavaScript. We support a URL syntax that directly names a self-contained web page with nothing but your Silverlight Streaming-hosted application. You can use this URL as the source of an <iframe> tag to embed the application on sites that don’t allow JavaScript. For example, you can add a Silverlight application to your Windows Live Spaces site by using the HTML Sandbox widget from Read more about this new feature in the Silverlight Streaming SDK.
    • You can now host videos in Silverlight Streaming while hosting the Silverlight application on your own web site. Doing so allows you to have greater integration and interaction between your web page and your Silverlight application. For example, you could build a video browser that used AJAX to talk to your web site for browsing and then made script calls to your Silverlight application to display selected videos. Of course, you can still package your content and data in a single Silverlight application and host it in Silverlight Streaming as you do today. Read more about this new feature in the Silverlight Streaming SDK.

  • This thread is coming to an end...

    Such posts will now be replaced by a news feed on (with an RSS feed that you can subscribe to). The SDK -- that will remain for a few more days on the DevLive portal -- has already been migrated to MSDN and will be updated in its new location only going forward. The tree navigation to reach it is the following:

    MSDN Library | Web Development | Windows Live | Microsoft Silverlight Streaming SDK

    The bookmark to the new SDK location on MSDN is

    So watch for those changes on and keep the feedback coming.

  • Hi,

    We are working in a Silverlight project to stream videos. 4Gb of video streaming storage will be insuficient for this project. Can we contract Silverlight streaming service with bigger storage? Can you refer ISP offering this type of service?

     Thanks in advance,

  • A simple and fully functional low tech workaround to your problem is to provision several Silverlight Streaming accounts and do the laod balancing in your app code. You can share the content across those accounts.

    Another option is to use each user's storage through the app.

    A good example of what can be done is visible on

    There is also a QuickApp on with code samples that you can leverage directly from to build your own app.
