Microsoft rechristens Silverlight 1.1 as 'Silverlight 2.0'

Summary: Microsoft has decided the next version of its Silverlight Flash-competitor is more worthy of a 2.0 moniker than a 1.1 one. A beta of Silverlight is due out in the first quarter of 2008, Microsoft officials are saying.


Microsoft has decided the next version of its Silverlight Flash-competitor is more worthy of a 2.0 moniker than a 1.1 one.

Microsoft rechristens Silverlight 1.1 as ‘Silverlight 2.0?On November 29, Developer Division General Manager Scott Guthrie blogged that Microsoft has decided to rechristen its next Silverlight release as 2.0. Microsoft plans to make a beta build of the next version of Silverlight available under a "Go Live" license in the first quarter of 2008, Guthrie added. (A Go-Live license allows users/developers to begin deploying applications in production based on the beta.)

Microsoft made an alpha version of Silverlight 1.1 (now Silverlight 2.0) available to testers in April 2007. The final version of Silverlight 2.0 is due out in 2008.

Microsoft shipped Silverlight 1.0 for Windows and the Mac OS platforms earlier this fall. Silverlight 2.0 adds support for ASP.Net Ajax, Language-Integrated Query (LINQ) and JavaScript, as well as support for Visual Basic, C#, Python and Ruby, which it will make available via a new Dynamic Language Runtime (DLR) layer.

Novell is building a version of Silverlight 2.0 that will run on Linux, which is code-named Moonlight.

Microsoft is positioning Silverlight -- formerly codenamed "Windows Presentation Foundation/Everywhere," or WPF/E -- not only as a multimedia player, but also as a development and delivery vehicle for Rich Internet Applications (RIAs).

I'll be interested to see if Microsoft ends up using Silverlight as a way to deliver applications like Word in the not-too-distant future, a la Adobe's Buzzword. I bet it's not a matter of "if" the company will do so; it's more a question of when. Do you agree?

  • A quick correction

    I just wanted to point out that the standard .NET languages (C#, VB.NET) will be supported in Silverlight 2.0 by a portable CLR framework and not by the DLR framework. The portable CLR framework (not to be confused with the compact CLR framework) will be shipped within the Silverlight install and run within the browser.
    • DLR

      Hi: As I understood this, when MS announced the DLR, they said it would support dynamic languages like Ruby and Python, as well as (Dynamic) Visual Basic. See here for more:

      They also positioned Silverlight 1.1 as a vehicle for bringing the CLR cross-platform. The CLR inside Silverlight is a stripped-down CLR that is codenamed Tolesto.

      So, yes, the existing .Net languages are supported via the CLR. I will take the C# reference out of my post. Thanks.

      • Re: DLR

        Sure, no problem. This is a big deal for us as it means we can use C# as a client-side language for our web applications, something that will ease a lot of our ASP.NET burden. Also the non-dynamic version of VB.NET will be supported.
  • lol...M$ delivers!

    when they failed to deliver 1.1 what do they do?...
    They increase the version to have an excuse for not shipping on time!
    M$ is the king of FUD and false advertising!

    • Pretty funny

      The trolls get louder but never any smarter. I didn't realize "M$" was still used anymore, I thought it went out of style back in 2001. Are we still ending superlatives with the word "NOT!!!!" too? Just got a call from the Simpsons "Comic Book Guy", he wants his stereotype back. Glad to know the trolls haven't evolved...
    • Troll. Why do you care?

      You're a Linux boy. Why should you care about Silverlight?

      Oh wait. You don't. You're just being a troll, like all the other Linux zombies.

      Seriously, Linux guys need a life. A social life.
      • Wait a sec...

        The article DID mention that Novell was doing up a Linux version called "moonlight..." So it's sorta relevant to his kind.
    • False advertising?

      Ok Trollboy... Where in the article does it say that the product was delayed? Hmmm?

      In fact, a google search for any delays in the product doesn't seem to bring up any hits either. It would seem the product IS on schedule.

      So it would seem that would make YOU the QUEEN of FUD. Go back to the basement and STFU.
  • Surprised by more Bloatfarm Bloat "Marketing"?

    As everyone knows, anything from the Bloatfarm is utterly useless and unusable until the sixth iteration.

    This is simply a way of hornswoggling the customers into believing that something useful has taken place.

    It is like an army marching at lockstep: much noise and movement; no forward motion.

    More Bloat from the Bloatfarm.

    • What Bloatfarm?

      Where is this "Bloatfarm" that you speak of?

      As far as I know, your post is irrelevant.
      • Bloatfarm...

        If I decoded the troll's post, I think he means Microsoft.
  • Silverlight vs. EcmaScript4 aka JS2

    Microsoft is pushing it`s own runtime and trying to slow down development of 'open' browser platform:

    I`m as a web developer on the same side of barricades with Mozilla.
  • We need to ask Adobe to release new ideas in order to improve Silverlight.

    Since Microsoft is not creative at all we should ask Adobe to release new ideas with Flash to improve Silverlight 12.0

    Come on! I will stick to Flash and never move to Copylight - Sorry Silverlight.
  • RE: Microsoft rechristens Silverlight 1.1 as 'Silverlight 2.0'

    Wow! Post an item about a product name change and include the word "Linux" and watch the trolls come out of retirement.

    I think Microsoft will actually provide a lot of new category RIA applications on Silverlight rather than old-school word processors similar to Word. They will have an offline story for those programs. Better yet, it will kindle enthusiasm for WPF-based desktop applications.

    Hmmm, did I say "kindle"? Oops, more flamebait ;-)
    • No flame...

      [b]Wow! Post an item about a product name change and include the word "Linux" and watch the trolls come out of retirement.[/b]

      I think you've got it the other way around - it's mention Microsoft in any sort of positive light - and THEN the trolls come out of the cracks in the woodwork like cockroaches.

      The mention of Linux is irrelevant because every "true believer" of the Linux faith knows that Novell is evil as they sold their souls to the devil (read: Bill Gates) himself.
  • How?

    I just don't understand how Microsoft plans to rip Macromedia's Flash hold from their hands and replace Flash with Sliverlight, their *gasp* Flash clone. I'll be quite interested to see how this plays out, to me it seems like in order for Silverlight to be a success it has to somehow offer benefits for developers that currently rely on Flash and it has to remain multiplatform as Flash currently is. It doesn't currently appear to be multiplatform but a big benefit of Flash is not just that it can run in a browser but that it can run in a browser and act the same way on any platform so I would imagine compatibility on Mac OS X and Linux will be a necessity if Microsoft wants this product to get anywhere.

    • I think it's about the developers

      From my somewhat career-oriented perspective in the trenches, both Flash and Silverlight have a huge advantage to me over other web development technologies because I can program them with a familiar desktop-like UI event model, and not worry about Postbacks, states, and the like.
      Taking this further, Silverlight's big advantage over Flash is that you can program Silverlight in C# (or VB.Net, or other .Net language of choice), whereas with Flash you have to learn ActionScript. Not that ActionScript is particularly hard to learn, but where to do take it outside of making groovy web controls? (Well, there's Flex programming, but you're still stuck on the Web). Whereas if you're a C# (or whatever) expert, you can use the same language and design idioms for Silverlight web programming, desktop apps, services, etc. It expands my marketability.
