It wasn't working so I boiled down my code a bunch and ended up with these 2 lines: var wc = new WebClient(); var result = wc.DownloadStringTaskAsync("http://www.weather.gov").Result; If I run this method with a console app on my windows machine. Its works as I expect and I get a string with the contents of weather.gov. If I run the same 2 lines in the constructor of App in a

问题 I'm currently developing a wp7 app (don't want to tell too much ;), but I'm struggling a little with the user interaction. The main question, I'm not sure about is: Should I offer an explicit save button in dialogs and use the phone back button as cancel, or should I save implicit the time the user taps the phone back button ... The more I think about, the more I'm unsure about the best user experience. I already read the user experience and interaction guide from Microsoft, but there isn't

问题 I need a control to enter small numbers on Windows Phone 7 and would like to have some kind of endless spinner control like the one for entering day and month and the date setting of the device.

问题 I want to show in WrapPanel a list of images. How can I do that or maybe I shall use other control ? 回答1: You can absolutely use the WrapPanel to show a list of images, scrolling vertically or horizontally. To get the kind of panoramic tile effect like in People hub with your images, you could do something like this: <controls:PanoramaItem Header="something" Orientation="Horizontal" Margin="0,-15,0,0" > <ListBox Name="SomeList" Margin="0,0,-12,0" ItemsSource="{Binding SomeItemsList}" >
