Introducing Microsoft Silverlight

  • 아티클

It is with tremendous pleasure that I can reveal Microsoft Silverlight: our next-generation, cross-platform, cross-browser web client runtime. Silverlight (previously codenamed "WPF/E") is a lightweight subset of XAML for building rich media experiences on the web.

There's lots of material at the NAB virtual press room site, but I thought I'd share my top ten list of reasons why you might want to use Silverlight:

  1. It supports playback of WMV files on both PC and Macintosh, with many options for interactivity during playback; with just a couple of lines of code, you can provide a platform-neutral way to handle all your movie files. Silverlight supports full-screen 720p video and offers seamless transitions between full-screen and windowed mode without losing your position in the video (something that media sites are crying out for today). 
  2. By separating markup (XAML) from code, Silverlight provides a familiar web metaphor for designers and developers. You can embed XAML directly within an HTML file if you want a simple, monolithic solution, or you can keep the two separate to enforce a delineation between different web development roles.
  3. Silverlight and HTML integrate seamlessly together. Every XAML element can be accessed or manipulated from the same client-side JavaScript that would be used to interact with any DHTML element: there are no artificial boundaries or barriers, and you can even overlay HTML elements on top of Silverlight content (simply by creating a windowless frame). We'll also make it very easy for an ASP.NET AJAX developer to add Silverlight content.
  4. You can embed XAML directly into your HTML pages; there's nothing binary or opaque about the format. There are only three steps necessary to add animation or media to your RIA application: (i) include a standard JavaScript file in your HTML header; (ii) call a function to create the Silverlight object anywhere on the screen; (iii) add some XAML content (an animation, some media) for runtime delivery.
  5. You have full runtime interactivity with Silverlight content. The contents of the XAML file can be completely server-generated, to contain information populated from a database. From JavaScript, it's just a matter of calling the createFromXaml method to add or remove elements dynamically at runtime. There's nothing that you can only create or manipulate at design-time.
  6. Silverlight is just a 1MB download on a PC (slightly more on a Macintosh because the universal package contains both Intel and PowerPC versions); it supports Windows XP and above, with Windows 2000 support to come.
  7. Silverlight is blindingly fast - for example, you can play many videos simultaneously without stuttering or dropping frames (subject to network bandwidth, of course). We're introducing a new video brush in Silverlight that allows you to use video as a texture for any 2D object (a rectangle, an ellipse or a path). This is going to allow designers incredible power to use media in new ways that have never been accessible through other existing technologies.
  8. Silverlight is both client- and server-agnostic. There's no difference between the Macintosh and PC runtimes; you don't need any Microsoft software on the server if you don't want to - you can deliver a great Silverlight experience from an Apache / Linux server to a Mac OS 10.4 client.
  9. Silverlight is almost 100% upward compatible with WPF. Animation, 2D vector graphics, media, text - they're all present in Silverlight and the concepts you've learnt in WPF carry forward (although Silverlight is a subset - it doesn't support WPF features such as 3D, data binding or templates). You can use the same tools (e.g. Expression Design) to generate content for Silverlight; you can take XAML from Silverlight and use it in a WPF application when you want to scale up and take full advantage of your local machine.
  10. Ah... #10. I can't reveal this yet - there's a big surprise up our collective corporate sleeve that will be announced at MIX. I hate to hold back on you, but anticipation is part of the pleasure, as my mother used to tell me as a child when I was waiting impatiently for Christmas to come!

Now that Windows Vista is done, I'll be shifting the focus of my blog slightly - I'll still write just as much about WPF, but I'll also start to write about its web-based little brother, since they both are part of the same continuum and my day-to-day job incorporates both technologies equally. Rich interactive web-based and Windows-based content; it's an exciting time to be a client platform evangelist!

    New video brush, what's wrong with the original Video Brush in WPF.  Do you mean new to Silverlight? No Databinding!!  That's like C# without classes !  It makes porting code between WPF and Silverlight very difficult.  It basically removes the whole MVC architecture.   No templates imply that there won't be any real ItemsControl support either (listboxes etc).  If there is then it's going to be really limited and perform like a dog for large lists. So will no. 10 be the not so secret cross platform mini runtime?  I hope this makes it into v.1.  I also hope this makes it onto my phone, zune and some future XBOX RIA platform.

    Amazing. Cross-platform compatible usually means that it can handle Windows and Macintosh at minimum (and should also include Linux). They even claim Mac compatibility. Too bad the demo video won't play on my Mac; neither inline in the Web page nor if I download the stand-alone file. Typical.

    Tragic. Microsoft loses .00001% of the user community, which detests them anyway, by not supporting Silverlight on Linux. I love how MSFT treats those particular losers for what they are. Obviously MSFT could support Linux as the code already runs on unix. HAHAHA, boohoo it isn't open source, boohoo MSFT doesn't love us. When will they ever tire of barking at the moon?

    I second the need for compiled c# possibly they will allow the compiled code to include only the dotnet bits used in the app into the bytecode, do this and the apps are a little larger, but you never have to worry about what framework version you are working with. Now that would be so cool...

    Is this an open standard? No. You claim cross platform. That term generally means it can be arbitrarily cross platform because the code base can be appropriately modified where required. You have written an application that happens to be targeted to two different platforms. Not the same thing. m32r, armeb, SuperH, ppc64, AMD64, S/390, IA-64, HP PA-RISC, MIPS CPUs, ARM, Motorola/IBM PowerPC, Alpha, Sun SPARC, Motorola 68k, Intel x86 / IA-32 are the architectures supported by the Debian project. THAT, is cross platform.

    "...cross-platform, cross-browser web client runtime..." Dual-platform, not cross-platform. And what other browsers other than IE will bother implementing inline XAML parsing? This is tiresome. You guys know that the Mac isn't much of a threat to MS because people are too in love with commodity hardware and Apple will never offer a platform based on commodity hardware. But you also know that Linux in the enterprise is a sleeping giant. All I can think of when I read another silly anouncement from some bottom-feeder or PR flak (and that's basically what an evangelist is, folks) from Microsoft that conspicuously ignores linux is just how much you've become like the IBM of old that you all dismissed back in the day as a sclerotic, disorganized mess, sacrificing new opportunities to protect old entrenched products. How much good MS technology is going to go to waste because the inferior Windows franchise needs to be protected? If you offered a version of Office for linux, half of your corporate desktop Windows licenses would disappear overnight. I know plenty of IT people who would drop Windows like a bad habit if Office was available for Linux. And you know it. We already have much better alternatives to Windows for IT-managed desktops - are you going to capitalize on the natural move to commoditized operating systems by making your other technologies and products like Office and .NET the standard there, or are you going to wait for those to be commoditized with free versions, too?

    Adobe already has a product with wider customer base compatibility.  Why would anyone consider SilverLight?  To reduce their customer base?  To eliminate potential revenue?  To reduce customer satisfaction?  I'm not seeing a business reason to use this product over the (existing, established) competition.

A: "Microsoft is gathering feedback from customers like you on Silverlight and to help determine which platforms should be supported in the future." Microsoft, don't ever claim Silverlight is "cross-platform" if you can't support other OSes besides Windows and Mac: why the need to ask for further feedback when it is obvious?

    Jeez, interesting polarization here: half of the people are delighted by Silverlight while the other half is disgusted, and the technology has only been announced a couple of days ago ;). BTW, have you noticed this: in this case, Microsoft is actually boosting competition as Adobe was essentially the only game in town. That's some twist. As for the Linux plug-in: I believe it actually was mentioned by one of the presenters at MIX 06... If I'm right, it was at least considered, possibly kept as a surprise? In any case, Microsoft is not doing this cross-platform thing because Steve Ballmer has suddenly seen the light but because of the antitrust suit. They have to play nice, and if a minor thing such as a browser plug-in could convice the court, it would be a small price to pay.

    Microsoft isn't getting it.  Their business model of locking consumers into their products is failing.  It worked marvelously for a decade when they were the only suitable desktop offering, but that time has passed.  Consumers are now demanding options.  As of April 10, 2007 Dell has stated intentions to provide Linux preinstalled on it's PCs.  There are already several articles pre Vista noting that MSFT is a sinking ship and unless it changes the way it does business it is dead in the water.  Vista has only proved this point more valid. I'm no expert, but I believe MSFT should stop trying to maintain a stronghold on the desktop market, and get back to it's roots as a Software company.   Focus on MS Office, and making it compatible and able to run Natively on all OS's.  Had they done this a few years ago OpenOffice would not be near the contender it is now.  Stop copying GOOG and develop some truly ingenuitive Online Content, or purchase some start-ups.  Siverlight is a good step, but it needs to be truly cross platform as stated in other posts, as well as .NET.  They are about to find themselves in the same position with mono and .NET as they are with OpenOffice. Obviously I am a Linux user, but I don't hate MSFT as much as my counterparts.  They can still turn things around and maintain leadership in the technology business.  If they keep traveling down this road of forced dominance however, their going to end up on a dead end street.

    So i went to the silverlight page, and the movie wouldn't play... i figured maybe i needed the plug-in for it to work. I down loaded the plug-in. relaunch my browser... and the page still wouldn't play the movie. if Microsoft's plug-in can't play the movie on the page announcing it, why on earth would i expect it to play anything else and why should i leave this thing on my computer?

    Well, i wonder how long Silverlight will stay cross-platform. It'll fade away on the Mac side over time, just like how WMP did. Microsoft is, NEVER, truely cross-platform, EVER.

    If #10, that you can't reveal, is not a cross-platform standalone runtime to compete with Adobe Apollo, then Silverlight is already losing the battle.

    All those people complaining about lack of Linux support. Have you seen any statement as to how Linux will NOT be supported? I haven't.. Also, an open source implementation will no doubt appear sooner or later if this grabs hold of the market, whether or not a MSFT Linux client is available. Just like it happend with Java until they decided to go open source. Only this will be easier, since the technology is simpler.

    shiny! i'm going to one-way startrek-"download" my linux kernel into it's own /dev/null and get right on this silverlight thing. seriously - xaml/.net/etc are second-rate protocols/languages/apis.  using them not only limit the width of your expression because of the shear inadequacy of the microsoft approach to programming (powershell -- an interactive shell -- with static typing. my fingers hurt just thinking about it), but it locks the result of your efforts into a format whose primary/defacto implimentation is proprietary... just admit up front that you won't have anything to show for your next 6 years of programming an ms language/living the "microsoft lifestyle" and you might not regret it so much in 2013 when they don't support it anymore. doesn't microsoft control enough of your data? how many of you have your resumes in .doc format? in short -- i take offence to enrico. your personal freedom is worth taking seriously.

    Sigh, so many trolls on this thread... Despite having an extensive (10 years) open source background, Microsoft was kind enough to invite me to Mix07 to learn more about what they have in the works. I was simply blown away by Silverlight, it's easily the most compelling technology they've released since .NET. No word on whether it would run on Linux yet (frankly I'm not sure why Microsoft should bother) however they've already announced IronPython and IronRuby support, so it's a start. In summary, this is good stuff, don't knock it until you take a look at it. -Jason

    Tim - how does Silverlight sit with ASP.Net and AJAX? Do you see them as complimentary technologies, with wilverlight providing the rich media capabilities that these two are lacking?

    I would say if it runs on MAC OSX and Windows platforms - you have already captured 98%+ of the desktop browser OS platforms in the market. Linux and Unix are traditionally server-side operating systems. If the long proclaimed day arrives when Linux becomes a mainstream desktop OS (it's been proclaimed for 10 years now), I no doubt believe Microsoft will release a version for Linux. But since that day is still in the future - I don't know why anyone would forgo ease of development and competition in the market based on the fact SilverLight does not currently support what is currently a server-side OS such as Linux.

    Microsoft changed the name of WPF/E to Microsoft Silverlight. This has to be the first time I've seen Microsoft go from a production-like name (WPF/E) to a codename (Silverlight). I guess they figured they needed something nicer than the usual jargon.
