Silverlight 4 Beta Gets the Thumbs Up

I've been talking to a lot of Silverlight developers and experts over the past couple weeks, as part of a cover feature we are doing on Microsoft's next version of its rich Internet application (RIA) platform, which was released in beta form at PDC in November. Given how quickly Redmond turned the crank between Silverlight 3 and 4, I figured the beta might be a bit rough around the edges or missing a few critical pieces. So I was pleasantly surprised to hear that the current beta of Silverlight 4 is, in fact, surprisingly robust.

Ben Dewey, a senior software developer at consultancy twentysix New York, has been working with the Silverlight 4 beta since it came out. He said he hasn't encountered any problems and said there is no indication that features are missing. "I haven't run into any non-implemented exceptions or anything along those lines," he said.

Evan Hutnick, a developer evangelist at component maker Telerik, told me he's spoken with a number of customers currently using the beta release to develop Silverlight apps, and they "seem really confident in this beta right now."

I'm hearing these kinds of comments from just about everyone I talk to.

The current beta of Silverlight 4 doesn't carry a go-live license, so obviously it's way too early to start releasing software based on the current code. At PDC, Microsoft's Scott Guthrie offered a release time frame of the first half of 2010, but it certainly seems like the final version of Silverlight 4 could emerge sooner rather than later.

Have you been working with the Silverlight 4 beta? What are your impressions of what Microsoft has delivered? Comment below, or email me at mdesmond@1105media.com.

My overall experience has been excellent. Like many business app developers, I have been waiting for things like Printing, Right-Click, and Drag and Drop. The team has really nailed these features - they are easy to implement and are much more mature than I would expect from a first version. I will say that I am not happy with the RichTextArea, or the fact that the Clipboard API does not retain any text formatting, but I can accept those considering how good everything else is so far.

I have had some issues with the RichTextArea control, e.g. (1) paste a text with length larger than 4096; (2) put the cursor after a Hyperlink and start erasing ... ; (3) selecting a Hyperlink always changes the current URL (even with target="_blank"). Tried unsuccessfully to find a place to report these.
