问题 How do I download and store a jpeg image from the internet in a Windows Store App with Windows.Web.Http?

问题 We are developing an app for Windows 8 in C#. Our app involves drawings the user creates, and we'd like to incorporate their drawings into the live tile. I have found examples of setting text and pictures as your app's live tile. Is there a way to do custom stuff to render lines, etc.?

问题 I'm writing a Windows Store/Metro/Modern/RT app for Windows 8/RT that needs to receive UDP packets on port 49030, but I can't seem to receive any packets. I've followed the tutorial on using DatagramSocket to the letter, and I'm getting nothing. I know my sender program is sending data, as I can see it on wireshark.

问题 I am looking for the list of assemblies in the ".NET for Windows 8" profile. This is the profile used for WIndows 8 Metro-style applications, and like Silverlight doesn't use the full .NET framework. 回答1: .NET for Metro style apps — list of namespaces Converting your existing .NET Framework code — changes to the various APIs. 回答2: I don't see any list currently... and WinRT is expected to change alot till the official release in 2012... current information about assemblies/not available in
