Multiple Window support is one of the important feature in Silverlight 5. Using this you can have additional top level Window on top of your trusted Silverlight Out-of-Browser application. Yes, you read correct. It only works in Out-of-Browser Silverlight application and hence you cannot open it inside a browser.
So, what is this new Window and how to use it in our application? Let's have some discussion on it. After it you will be able to know about it more.
In Silverlight 5 Beta, Microsoft introduced the Window class to open additional window content from trusted OOB application.
