I love Silverlight. There. I’ve said it. I think it’s a fantastic opportunity for developers to write beautiful, client-side, apps using the tools they know and love – Visual Studio 2010. We can also use the gorgeous Expression suite (especially Expression Blend) to design and author rich, interactive applications.
Developing for Windows Phone 7? Want to make advertising supported revenue straight from your app? Microsoft has released SDK for that ;) You can download it here: http://go.microsoft.com/fwlink/?LinkId=198440
The SDK takes the form of an assembly that you can simply add a reference to in your project and start using straight away. You can add the reference in Expression Blend 4 or in Visual Studio 2010, and the assembly lives here: C:\Program Files (x86)\Microsoft Advertising SDK for Windows Phone 7\Microsoft.Advertising.Mobile.UI.dll.
