Silverlight Release Candidate due before end of July

Microsoft expects to deliver the near-final test release of its Silverlight alternative to Flash before July is over, according to a blog posting from a Microsoft technical evangelist.

Microsoft officially unveiled the beta of Silverlight 1.0 at its Mix '07 conference in April. The company also announced at that time the availability of an alpha of Silverlight 1.1, which adds a built-in Common Language Runtime engine, plus support for ASP.Net Ajax, Language-Integrated Query (LINQ), JavaScript, Visual Basic, C#, Python and Ruby. (No update so far on the status of Silverlight 1.1.)

Silverlight is a Web browser plug-in for playing media files and displaying interactive Web applications that was formerly codenamed "Windows Presentation Foundation Everywhere," or WPF/E.

Tim Sneath, a Microsoft client platform technical evangelist, posted the update on Silverlight availability to his blog on July 13:

"In just a couple of weeks, we'll be ready to publish the Release Candidate of Silverlight 1.0 to the web. We're in the final stages of stabilization as we close in on launch; fixing the last few bugs, doing detailed security penetration testing work, resolving any remaining inconsistencies and completing the last fit and finish work."

Sneath and his colleagues are talking about the release candidate now in order to help developers who've been working with the early code avoid some of the Silverlight changes that could break their pages, Sneath said.

Microsoft is making available for download a "special preview SDK (software development kit) release that will allow Silverlight developers to make sure their Silverlight objects work on both the March beta and the soon-to-be-released release candidate, Sneath added.

The final gold version of Silverlight 1.0 is due to ship this summer.

  • nobody carres about silverlight

    Who would want to use this plug in when it has no support on Linux?
    It's just an extra security hole!

    • Novel has already announced plans to provide silverlight support on linux

      Since Novel will be bringing this out on linux it looks like it will be a pretty attractive option. I don't think it could be much more of a security hole than Flash is and the programming and debugging looks vastly superior to Flash. Im thinking about playing around with it on windows to get a head start in learning it before the linux version is ready.

      • Right, MS buys Novel with hundreds of millions to create a crippled Linux

        version. The talk about Silverlight on Linux is just smoke and mirrors.
    • Huh? Of course its supported on Linux.

      WPF/ EVERYWHERE. Got it?
      • Right, I can hear the foot dragging and the excuses already.

        The versions for Linux and OSX will be slow in coming, and with fewer features.
        • Nothing stops you from improving Linux

          • But, the issue is that there is a lot stopping MS from supporting ANYTHING

            that will work equally well on Linux. That is the problem. We know full well that MS trying to say this will work on Linux is just smoke and mirrors.
      • really?

        M$ was not able to implement it on it's own windoze yet, and you see it running on Linux? LOL...
        I think you were looking at some product that has nothing to do with software, like some bulb or something.

        • Your cluelessness is amazing.

          Do you not read anything but ZDNet???
          • He is just observing MS behavior. They need to make sure things are not

            compatible. Pretty well documented.
    • I have an idea...

      Why don't you and Donny Boy go get a room somewhere?

      Better yet, I think Donny boy has an extra air mattress in his momma's basement where he hangs out eating store brand Doritos and reading his collection of JC Penny's mens underwear catalogs. You could go over to his house and work on your ignorant posts together.

      Now, doesn't that sound nice?
      • Well played ol' chap!

  • Will iPhone support it? n/t

    • No, afraid not.

      Unless Apple works aout a deal with a license from MS.
  • Yes it WILL run on the iPhone

    Since the beta runs on a Mac then yes it will run on an iPhone


    Why anyone (or Mircosoft) thinks that we need another Flash is beyond me.
    • Sorry but no.

      Apple would need a license from MS first.
      • Licensing has nothing to do with it.

        It's a freaking plug-in, dolt.
        • Yes, no and sort of.

          Currently the iPhone can't support it. But yoiu may be right in that MS may give Apple a run time for it. Have to wait and see.
    • Easier for .net people.

      Silverlight uses the .NET framework. It will make it easier for people familiar with .NET framework do develop applications with it.
    • That's ironic.

      Nobody says why do we need another OS, we have Windows. Or why do we need another browser, we have Mosaic etc. etc. <br>
      Silverlight is perhaps significantly better than Flash Player and it gives choice to the end users? Could that be it? <br>
      So why wouldn't anyone be interested in another player like this that is extremely lightweight, completely standards compliant and totally cross platform? <br>
      I'll bet there are a lot of content providers that use Microsoft products right now who are eagerly awaiting Silverlight.
