问题 Ok so I am trying to learn how to work with XAML and how to build new windows metro applications using Visual Studio 11 Developer Preview.

问题 I'm using signalr to do some real-time events in my web application.

What else do I need to do to enable web sockets support in signalr? 回答1: Ensure that your app is using the .NET 4.5 assembly from the SignalR package. If the project is targeting 4.0, or

问题 I'm creating a Windows 8 Metro App with c# In the app you can search persons in a phonebook. Is there a possibility to add a found contact to the users contact-list? I know you can browse the contacts with the Windows.ApplicationModel.Contacts.Provider, but I can't see how you can add a contact. thanks for help 回答1: You can do so through the Contact Picker Contract.
