Although it was great to see that my post on Silverlight got picked up in a few places (in particular, Digg and TechMeme), it certainly generated a lot of feedback in the comments section! I hope that after reading the comments, you'll at least give us a tiny amount of credit for being open and transparent - I haven't censored the posts that I didn't like the look of :)
It's interesting to read all your feedback, and I can promise you that it is taken seriously. At our next leadership team meeting, I'm sure we'll be poring over all the commentary and trying to incorporate a good deal of it. To address a few points:
Enough said. I'm not writing this to be defensive: everyone is entitled to their opinion and I'm committed to provided an open channel for feedback, positive or negative. But I also wanted to show that I do read every comment and am interested in the discussion. Our success or failure with Silverlight is contingent on whether we satisfy developers like yourselves - time will tell how we do, but I hope that you'll at least give us a chance to earn your trust.
You've probably had your fill of feedback, but what the hell here's some more. Given the software development that I'm involved in here's a list of my priorities as far as Silverlight functionality is concerned in priority order:
1) CLR support (at least at the compact framework level of functionality).
2) Decent System.Net.Sockets support with security controls, but fully functional otherwise
3) Linux support. I don't want to have choose a non-dot-net solution if Linux deployment is required.
4) A standard data-binding mechanism within the Silverlight APIs
5) Windows Mobile support.
6) The ability to embed the Silverlight plugin into native applications across the platforms supported.
Silverlight is a very exciting technology that has the potential to change the software/web landscape, but man will I be disappointed if there is no binary sockets support in the first version and Linux support within a year. Its potential is probably why you are getting a barrage of positive/negative feedback.
Please make a mac version of Expression Blend to support Silverlight. Most all serious designers use Mac's and I think to exclude them is risky.
Nice job with silverlight.
The question what do you think of the idea, and what dou you think the future would be like for my jsc project?
As silverlight is now solid enough i think i should start using it my examples.
It's great to see MS re-entering the rich web graphics arena after allowing Flash to monopolise the market for the last 9 years. Does anyone else remember Microsoft's Java-based "Liquid Motion"?
(See http://www.internetnews.com/dev-news/article.php/53651 and http://www.microsoft.com/mind/1198/liquid/liquid.asp ).
I believe MS originally acquired Liquid Motion from a company named DimensionX (see
http://www.softlookup.com/tutorial/games/f21-10.gif ), but sadly it became a victim of the "Don't Mention the 'J' Word" sentiment that has ruled at MS since the late 1990s - this is Microsoft's loss, since Flash has gone from strength to strength since then.
Silverlight looks very promising to me as a developer, mainly because I can write code in C#/XAML and have it compiled and run at full speed on the client machine, rather than having to use an awkward scripting language with poor development tools.
I hope you guys have also added some kind of document viewing support - something like "Metro", perhaps? (See http://www.theregister.co.uk/2005/04/28/metro_longhorn/ ) - it would be great to finally move away from the bloated, clunky PDF format and the truly awful Acrobat UI.
Finally, let me add my voice to the chorus calling for Linux support to be added as soon as possible. This is a good start, but I'm sure you know you have a long way to go yet...
Oh, and "Metro" == "XPS", for the uninitiated...
I could see how you could get easily discouraged with the negative comments and feedback you're getting. Don't Be! We are extremely excited to have Silverlight; we have products that we wrote for the web that we're going to use WPF to rewrite in desktop mode. And we'll now be able to use that presentation framework goodness in on the web! Great things all around.
Well, if you want some feedback, it could use some Opera support. Opera needs more love in general, really :\
A lot of the advanced JS out there (including stuff using Prototype and Dojo) binds arguments to callbacks with closures, so it would be really nice to support anonymous functions.
Also, where's the right place to report/discuss bugs?
No source code = no use for me and every other Web 2.0 developer.
Nice try though, good to see MS can still keep the dream alive 90s style. That video is absolutely hilarious - it's like a parody of itself. What did you tell the marketers? "Hey guys .. make us a video depicting what using a Windows PC is absolutely NOT, and NEVER WILL BE, like! Extra points for token diversity, kids and cool stuff like skateboards! Skateboards are still cool, right? Right?"
God that is lame - a really expensive form of lame, which just makes it all the funnier.
Anyway keep it up guys. PS some of my friends are already calling your format "Silverchair" - lol!
Hey, Silverlight really rocks. I wonder if it supports layers?!
For example I have 3 images I want to send the last one to be on top of the other, or the one on top to be behind the others etc..
Do you have any idea how to do that?!
What about Windows 9x support?
Tim Sneath is awesome, if you don't read his blog , you should. You really, really should. He's
The guy at NAB said the download is only 1MB and you can stream HD Video with it. Please bring up how silly this statement is and include atleast the compact dotnet framework so we can run compiled code in this thing. If your streaming HD you probably don't care about downloading 4-5-6MB or more once.
Also please make silverlight a true lightweight version of wpf so that we can use a subset of wpf xaml code and components in siverlight, making it much easier to create a light weight cross browser client with limited functionality.
Thanks for pointing out that you are closely watching the feedback...
i'd like to echo dnl2ba's anonymous function request, above.
also, there should be some kind of extensability API for UIElement. for example, if I define a globally scoped function like this:
function MyLayoutControl (super)
this.KeyDown = function (sender, keyEventArgs)
// handle KeyDown event
this.ChildAdded = function (child, index)
this.GetValue = function (propertyName)
// override, or pass to parent
return super.GetValue (propertyName);
this.SetValue = function (propertyName, value)
super.SetValue (propertyName, value);
then including this definition in the XAML:
would cause the control to call "new MyLayoutControl (UIElement);" to create a wrapper object, adding non-overridden functions/properties to its prototype, hooking up events, etc...
Please, please, please ... tell me you aren't going to allow native code to run. Are you just renaming ActiveX here with a vector API?
Can you give me a percentage chance of exploits of this thing?
Why is speed/efficiency always touted over security at Microsoft? The compys today are plenty fast, they even make Flash run good... Could you at least add a "Silverlight is Secure, and here's why" link that at least explores how, this time around, you got security for annoying banner ads on the web right?
You don't get a pass from me when you get exploited. Although I'm not rooting for any crumbling of your foundation either. Just get it right. I'm so tired of the gaffs and the excuses from a company that has the resources to always get it right.
