How to store / access a global state object in Silverlight? (phone7)

I'm building an application on Phone 7 using Silverlight and need to maintain some state between pages. I was hoping to store an object in app.cs开发者_如何学编程 and access it from each page but I haven't been able to find any documentation on how to do this.

What is the best way to access the same object between many different pages?

Thanks for your time,

Answered my own question. I can access objects in app.cs by simply doing:

App app = (App)Application.Current;
app.whateverMyObjectIsCalled

Is this a reasonable thing to do?
