问题 Is there a javascript function I can use to detect whether a specific silverlight version is installed in the current browser? I'm particularly interested in the Silverlight 2 Beta 2 version.

So; why should I consider moving my WPF application to Silverlight 4 - given that I still want a desktop application? 回答1: Keep in mind that Silverlight 4 is currently in Beta

问题 I am trying to render text on a bitmap in a Windows Phone 7 application. Code that looks more or less like the following would work fine when it's running on the main thread: public ImageSource RenderText(string text, double x, double y) { var canvas = new Canvas(); var textBlock = new TextBlock { Text = text }; canvas.Children.Add(textBloxk); Canvas.SetLeft(textBlock, x); Canvas.SetTop(textBlock, y); var bitmap = new WriteableBitmap(400, 400); bitmap.Render(canvas, null); bitmap.Invalidate()

问题 Why do the Silerlight-generated WCF proxy class(es) offer only async calls? There are cases where I don't really need the async pattern (for example in a BackgroundWorker) EDIT : Sometimes I need to process the results of two WCF calls. It would have been much simpler if I could have waited (the business of the app allows that) for both calls to end and then process.. but noooo.... async! :P 回答1: There's actually a technical reason you can't do sync calls, at least from the 'main' browser
