Silverlight 4 beta now available

Microsoft have just announced Silverlight 4 beta today at PDC09, that is available for download today. Silverlight 4 promises to enhance the overall user experience, improving speed, performance and rendering for browsers.

Silverlight 4 was demonstrated today with some practical applications that are able to take pictures and modify the image in real-time, using a web-based service. The service lets you take a picture of yourself and modify it in real-time to adjust your appearance, and even change the colour of your shirt.

Microsoft released some statistics on Silverlight 3, being installed on 33% of all computers and mobile phones during summer 2009. Silverlight 3 is now installed on approximately 45% of all computers and mobile devices around the world today.

Silverlight was also demonstrated with Microsoft's own search engine, Bing, where it was able to split the image into a puzzle and scatter the image around. This application was also used with a YouTube video, being able to scatter the page and still being able to play the video in real-time.

A new desktop Facebook application using Silverlight was demonstrated using a drag and drop feature for images, including folder groups. The application demonstrated smooth scrolling through images and comments without any interruption.

Silverlight also showed off a video on-demand video third-party video application that allows the user to rewind, fast-forward and even pause live or recorded TV, all using your browser. Microsoft also showed off a demo of a football game that allowed multiple camera angles, even available for a live broadcast.

classic html file uploading sucks...
even without silverlight, you can do great multiple file upload enabled web pages with WPF (which is already installed on more computers than silverlight). It's a shame that big websites like facebook don't even care to use WPF to improve the user experience on file uploading...

Classic html doesn't suck since it works on every browser in every OS. WPF sucks because it only works on Windows. That's why a lot of sites don't use it. Webdevelopers are getting tired of all those OS specific stuff because in essence that entails they have to build the site again for every OS and every browser there is. By using OS independent stuff they don't have to and they can guarantee that it works.

so, you think a major website like facebook doesn't have enough money to hire developers to build custom solutions that enhance the user experience as much as possible, depending on the os/browser they use?

in fact they ask IE users to install some activex control to enable multiple file upload. So, they are perfectly aware that classic html file upload sucks. They just didn't choose to use WPF. That's sad, because WPF based websites doesn't need administrator or even user authorization to run, as opposed to admin or usermode activex controls installations.

Looks interesting, Sadly I can't currently test it as this PC doesn't have SSE enabled (AMD Athlon xp 1500+ 1.34Ghz)

IS there a Mac OS X version to test? (I'm getting a mac mini soon)
