Microsoft announces "Silverlight"


** Here you go Robert. My first post was a mis-click on the publish button (too excited). As you know, we have blogging guidelines and was asked to hold on to blogging about this until tomorrow morning so I had to take it off. Makes me feel like an ass to find out that others have already blogged about it. Oh well. **


Microsoft Silverlight

    Hey Loke,

    I got referred by Scobleizer too!  A mention from Robert is worth a thousand traffic.

    Just wondering… can you develop Sliverlight with VS Express?  And… what about the deployment in linux platform?

  8. WMExperts says:

    What’s great about Silverlight, though, it that it’s heavily cross-platform, supporting IE, Firefox, Safari, and – here’s the exiciting part, Windows Today at the 2007 National Association of Broadcasters conference (NAB2007), Microsoft

  9. Joe says:


    Isn’t the non-standard language support on the client a secret until Mix?

    RE – Tim Sneath’s blog:

    or is Tim hinting at something else?  I haven’t seen the .NET support announced anywhere else.

  10. Loke Uei says:

    Isaac: yeah you’re right! I gotta buy Scoble a drink one day 😉

    We don’t have the full details about Silverlight and our tools story yet. You’ll probably get all the information at MIX. Don’t miss it.

    Joe: I don’t have the full details about the language support but everything is done via Javascript / AJAX. Obviously if you’re using IIS and ASP.NET in the back as a server, you’ll be able to use the .NET assemblies etc.

    again, more at MIX 🙂 Give you guys a reason to go to Vegas for some fun!

    As has been blogged all over the place , WPF/E has been renamed Silverlight (Note: lower case 'L').

  14. rd says:

    I think some of these stats are fishy for Flash / Flex.

    XML (XAML)-based presentation layer for SEO: Well not XAML for sure… but MXML based presentation layer for SEO

    Some of the others are debatable.

  15. Ross says:

    Isn’t it a little disingenuous to say that Flash doesn’t support  Industry standard video codec when it in fact support the Industry de-facto web video format?  And complaining that it doesn’t support XAML is like claiming that Silverlight doesn’t support MXML.

    Other than that, an interesting read.

  17. Ed Bradford says:

    This page doesn’t display properly in Mozilla, Firefox or Opera. Checkmarks are displayed as u’s with an umlaut over them. Why is that?

  18. Loke Uei says:

    Perhaps you’re missing the "wingdings" font which is where the Checkmarks come from.

    I’ll switch it to "X" instead to be more "friendly".

    So TechMeme is chock full of news about SilverLight, including the patented Microsoft astro-turf announcement technique, where all the Microsoft WPF/Expression employees post the same links to their blog without actually saying anything new and substantive.
