Official Announcement: Live Mesh Expansion
Silverlight 2 BETA 2 released on Friday and is the best release of Silverlight so far! It is packed with features, with many much-awaited features like DRM coming into play!
On the media end, SL 2 BETA 2 supports server-side playlists, DRM and adaptive streaming (that was announced at MIX). I intend to post more technical details on these in upcoming posts.
One of the good things for developers is that many of the base Silverlight controls have been moved into the runtime, hence not requiring that additional piece of download when the app loads. That would make app loading really fast and app size really small!! That addition into the runtime has not increased the runtime size which is still around 4.3 MB for Windows.
A full-fledged post with all features is at ScottGu's blog here. This is a must-read for anybody who is interested in Silverlight! It covers the comprehensive list of features we've released in Silverlight 2 BETA 2 and in Expression Blend 2.5 June Preview.
Download Silverlight and Expression with the SDK/VS Tools here.
This was announced at MIX 08 and the product team has put its first BETA out already!
Windows Presentation Foundation (WPF), the superset of Silverlight used for building rich desktop experiences, has its third major update. The .NET Framework team today released the .NET Framework 3.5 SP1 and Visual Studio 2008 SP1, both as BETA and downloadable for free - offering a ton of features in ASP.NET, AJAX, Visual Studio, VB.NET and C#.
Scott covers it all in his marathon post here and Tim Sneath does a detailed write-up of the WPF features here. I thought I will highlight the key things that excited me (and had been waiting to talk about!):
Graphics Enhancements in WPF
Hardware accelerated Shadow and Blur effects: Pixel Shader effects that allow designers/developers on WPF to just add a line of code to get shadow and blur effects. The best part is that these automatically run hardware-accelerated. Best part: The effects model is designed in a way that developers can create their own re-usable effects. A detailed write-up of the effects model and a tutorial on creating your own effects is available here.
Improvements in Text Rendering, Animations, 2D Graphics and Startup: A whole lot of performance enhancements have been made, specially around text rendering in 3D scenes and with regular 2D animations. Performance has also been significantly enhanced for the cold startup time (when you load a WPF application for the first time).
HLSL and DirectX integration: DirectX developers can use HLSL and Direct3D integration in WPF, allowing for DirectX scenes to be rendered on WPF controls! This is huge for companies and developers that already have existing investments in DirectX and want to port any of it to WPF.
New Controls: WPF will have three new controls that are bound to be popular with developers instantaneously. A really rich DataGrid control that provides the most often used tabular data view, a WebBrowser control that will let you host browser-based applications in a WPF window and (hold your breath) the Office Ribbon control with full adherence to the Ribbon-UI guidelines!! That will enable developers to just build Ribbon-menu based applications with the least effort!
Deployment
OK, now the bigger part! One of the bane of WPF applications was the necessity of a huge .NET Framework installed on the system. The .NET Framework 3.5 redistributable is 197MB making it very hard to bootstrap to a WPF application that is being installed.
Introducing the .NET Framework Client Profile. This is a much smaller version of the runtime (expected to be only around 26MB!!!) that does not contain several of the server components (for example: ASP.NET) and only includes the assemblies required for client applications, namely - the .NET Framework core, WPF, WCF and Windows Forms. This also comes with a bootstrapper (~200KB) which can be included into your client applications. The bootstrapper will check for .NET Framework availability and then download the .NET Framework Client Profile setup package if it found that .NET Framework is not installed already. The bootstrapper is also smartly written to look at only incremental components - for instance, if you already had .NET 3.0 and your application required .NET 3.5, it would only download the incremental components, hence reducing the download size much further. Note that you will have to explicitly configure your application to require only the client runtime components while building the application.
Remember that since most Windows XP systems already have .NET 2.0 or higher, this should significantly reduce the download size for .NET Framework. This is probably the best update for WPF since its first release!!!
BETA 1 Notes
Much as I want to try all the great stuff immediately, remember that there are some incompatibilities of Visual Studio SP1 with the Silverlight 2 BETA Tools for Visual Studio. This will cause your Visual Studio Silverlight development experience to break. A new version of the Silverlight Tools will be released soon (see Scott's blog for more information).
Also remember that this is the BETA and not all features mentioned above (like Ribbon UI) are immediately available. See Scott's blog for details. But hey, we've made the announcements. And Scott's team has been pretty kick-ass in shipping stuff really fast!
Mrinal convinced Vineet and I to become Twitter-ers at the recent Barcamp we'd attended.
Mrinal also told me that twhirl was the best Twitter client around. I did try using Witty and it seems to be a little buggy at the moment. I have since decided that the world needs a better WPF Twitter client and intend to write one when I find time. In the meanwhile, it is actually quite painful to use twitter.com itself to keep track of all the people I am trying to follow on Twitter.
So I gave in and decided to also give twhirl a try (and in the process also see what things a twitter client should have). Now, twhirl needs Adobe AIR runtime to be installed and the integrated installer started off from the twhirl homepage.
It downloads it and then gives me an error that says:
I know Adobe AIR isn't very good with external devices, but then I do have a hard disk available! :) Time to go the manual install route I guess.
Sudha Hariharan, a Flex Enthusiast I met at the Adobe Flex UG, had an interesting email conversation with me on Silverlight. She has posted the same on her blog and you can check it out here.
Thanks Sudha - it was fun answering those questions!
If you are a Silverlight enthusiast and found a ton of features you wanted in Silverlight 2, here's your chance to say what you'd like to see in Silverlight 3.
Head over to Scott Barnes' MS Mossy Blog and type away your list!
Happy wishing!
Yesterday was fun. I had been invited to introduce Microsoft Silverlight 2 at the Flex User Group in Bangalore. I met a whole bunch of cool people and was overall great fun talking to them.
I finally got to meet Mrinal Wadhwa, the champion of the Flex UG in Bangalore. We had been chatting away on email for a while and it was good to finally see more of the person than his Facebook profile!
Supreet Singh, my partner in crime began proceedings to a fully packed room talking a little about User Experience. Just a little because the room was full with developers. So after that it was all demos and geek talk.
As expected, the conversation very soon got into a comparison between Flex and Silverlight 2. I did not want to really compare, but had wanted the audience to look at Silverlight 2 as a technology holistically. But I guess that is hard for anybody who's working on Flex day in and out. We had some interesting discussions about the evolution of Silverlight.
The DeepZoom demos were really well received. I was a little surprised to get the entire audience applauding the Hard Rock Memorabilia gallery and a few other DeepZoom demos I had with me. I had a question from Mrinal about uploading images to build a DeepZoom collection and I had said I would answer that later in the session - I intended to show the DeepZoom tool before doing that and never got the time in the end. So if you still have the question, do check out MS Live Labs PhotoZoom and learn how to build your own DeepZoom collections here.
When I showed the designer-developer collaboration using Blend and Visual Studio, there was some discussion in the audience about the whole workflow. We discussed about actual workflow of projects today which involved a lot of raster prototyping in Photoshop and then actual slicing/dicing to make the CSS/HTML that can be used in Flex (or regular web pages). We were running out of time for a more elaborate discussion, but there was some good feedback that raster is still very important to have in the overall designer workflow. I did mention that designers would use raster even in Silverlight projects. I could be way off here, but I got the impression that regular Flash work still used a lot of raster and did not leverage the obvious benefits of vector. Some people also argued that it was easier to get raster images than vector images and did not mind sacrificing the fidelity. Maybe an offshoot of not having more designers in the room!
Another interesting discussion was around performance. It obviously seemed that the biggest concern to Flash/Flex developers was performance and memory utilization of applications. In the Silverlight world, the CLR probably makes a huge difference in terms of performance. I did demonstrate some differences in the JavaScript and C# execution using the Silverlight 2 Chess application. I also think that though the underlying framework plays a huge role in determining performance of your applications, it is also a lot dependent on the quality of code. For Silverlight applications, there are some tips and tricks on building high-performance apps and if you are exploring this, you should check out Seema Ramchandani's talk here. Check out her blog and you'll learn a lot of what happens under the hoods.
There was some discussion around security and I had promised links detailing Silverlight security architecture in detail. The Silverlight security cheat sheet is the best way to get started.
We also talked a little about Expression Design and since we had the room for a limited time, we couldn't get to seeing more of the Expression toolset. Remember that you need Expression Blend 2.5 March 2008 Preview for Silverlight 2 (there are 3 versions on the Expression web site that is bound to get a beginner confused).
Finally, I thank everyone, especially Mrinal for inviting us over and giving us a chance to introduce Silverlight. I got some good pieces of feedback and will pass them on internally. I think overall there was interest and given that many RIA development concepts were already well-known to the Flex folks, it should be easy for them to give Silverlight a shot. Everything you need for getting started on Silverlight is available at www.silverlight.net.
Remember, there will be judgements, criticisms, praises and reviews all over. The best way to make a judgement is to try the stuff yourself. And if you did not like what you saw, give us feedback. If you liked what you saw, spread the word! :)
I presented a webcast today as part of our ongoing series of precursor webcasts to the Windows Server 2008, Visual Studio 2008 and SQL Server 2008 Launch. If you have not heard of the launch, you should head right away to www.heroeshappenhere.co.in and register yourself in one of the several hundred cities that we are taking this launch to in India.
I had a good audience and also felt that there was a lot of genuine interest in Smart Client Development. That is not so much of a surprise given that more and more applications have a hybrid software+services approach to leverage best of both worlds - desktop and web.
My session focused on 4 different buckets of Smart Client Development:
Smart Client Applications do not have a single definition. My view of these applications are that they are primarily desktop applications, that can have a few other "smart" features, such as:
Most of the above are a breeze with components and frameworks that are available today - and with Visual Studio 2008, development of most of these becomes even more easier.
The webcast showed how you can leverage the following technologies. I am not going deep into the demos here, because there were many, many steps involved and I am sure it will be tedious for you to read as well as have a high chance of missing something. I will point you to resources, including the recording of my webcast, to watch these instead.
The technologies I talked about today are:
Windows Presentation Foundation / Windows Forms
WPF is a great way of creating rich applications with vector graphic elements, 2D, 3D, document-oriented applications, etc. Windows Forms, a technology that has been around longer, continues to be a great technology to build desktop applications that forms-oriented, task-oriented (like a taskbar app, control panel, etc.) and do not require all the richness of WPF.
A more detailed discussion on which technology to use when is something I posted in this post a while ago. The best part is that the interoperability between these two is fantastic - both provide a "control" that can host the other into one of their "windows" - you can put a WPF control into a Windows Form or vice-versa. This means even existing Windows Forms Applications can start using some WPF richness for new features that require data visualization of high interactivity.
Microsoft Expression Blend and Visual Studio 2008 combine to provide a rich, seamless designer-developer process for creating these applications. Blend provides all the designer tools whereas VS 2008 provides all the developer power.
There are also new enhancements to WPF with .NET Framework 3.5 and you can find the entire list here. A video describing the features can also be found here.
Scott Guthrie also blogged about an update to WPF that we are planning to release later this year which will add more flexibility in deployment options and also provide performance boosts.
If you are a beginner on WPF, the community website is www.windowsclient.net and the best place to start is the WPF Video Gallery.
SQL Server Compact Edition
Another cool piece of technology I discussed today was SQL Server Compact Edition (or SQL Server CE).
SQL Server CE is the compact edition of the SQL database and was used in a prior version in the Windows Embedded/Mobile world because of the necessity of small footprint there. That technology has evolved now to provide a common base technology called SQL Server CE that you can still use in that world, but can also use in building PC applications. In here, you can actually embed a full database within your application and query data using ADO.NET with the same ease as you would if you were using SQL Server Express or higher versions SQL Server itself.
The neat thing about using SQL Server CE is that you do not need to have SQL Server (of any kind) installed on the client system. So it is a true database engine embed that doesn't need any administrative privileges or huge local services to be running.
You can learn more and download SQL Server Compact Edition 3.5 today from http://www.microsoft.com/sql/compact
A video tutorial of using SQL Server CE with a slightly older version (3.1) is available here and should get you introduced to the basic concepts.
Microsoft Sync Framework
Probably the coolest demo (at least according to the presenter :)) was showing off the Microsoft Sync Framework CTP Refresh 1.
Microsoft Sync Framework is one of those frameworks that you have to use to believe! It is unbelievably simple for the enormously huge tasks it accomplishes. It can do any kind of synchronization - between PCs, between PC/mobile/device, between client and local server, between client and Internet server, between databases - anything. Ask it to sync and it obeys!
With Visual Studio 2008, the integration is unbelievable. I did a whole demo of local client/server sync between a SQL CE database and a SQL Server database running on my system with part data locally cached, part directly accessed - all of it with just ONE LINE of code and in well under 15 minutes.
You might want to give it a spin yourself by downloading it from www.msdn.com/sync - you will need both the Microsoft Sync Framework and Microsoft Sync Services for ADO.NET v2.
Excellent video tutorials (albeit a bit lengthy) are available here, here and here. I used a large part of the third video for my demo today. The videos also contain customizations you can make to the Sync APIs that I did not have time to cover today.
ClickOnce
Finally we talked about ClickOnce APIs in .NET Framework for easy publishing and auto-update. I have uploaded the code I used today along with the presentation (link below). The simple demo I used today was based on this video that can walk you through the steps all over again.
Presentation and Demos
You can download today's presentation and all code samples I did today (finished samples) from here. (The presentation is in PPTX format - you might want to download a viewer here if you don't have Office 2007). I do encourage you to go through the video links I mentioned above as well to get more information - I was talking too many technologies in the 1.5 hour session - many more details are available in the videos that are dedicated to these topics.
The entire webcast on-demand recording is available here. You will need to register to download this, if you haven't already attended the webcast.
So there! My part of the promise to post all the links and the pptx/code is done. So now there's nothing stopping you from building awesome Smart Client Applications!!
Happy coding!
Developers and designers I meet ask me one perennial question - "What's coming in 2?"
Well, some clues popping out - specially this one by Jesse Liberty.
I tend to give another piece of advice to developers/designers. Expression Blend 2 December Preview is available (and has been for a while) and designers should download it today and start working on Silverlight 1.0 sites. It gives you a good grasp of the tool and gets you setup for designing with more features when Silverlight 2 releases. You also could try your hand at WPF projects and get a hang of some WPF data-binding features as well.
Developers on the other hand should look at the coding aspects of WPF and can also get familiarized with the XAML DOM using the Silverlight 1.0 SDK. Most of the concepts of XAML and vector drawing, brushes, etc. are explained very well in the documentation and samples that come along with the SDK. Get it today and learn it inside out. If you've already done that, revisit it to see what topics you haven't familiarized yourselves with.
Other than the books Jesse Liberty put up on his post, I'd also recommend Laurence Moroney's excellent introductory book on Silverlight 1.0
If you are a new developer to Silverlight, this is one book you should get!
