System.Property<T> refactored out of Silverlight 4 System.dll?

Question

I'm in the process of migrating a Silverlight 3 project to Silverlight 4 (plus RIA Services v1.0 RTW and the latest drop of Rx.) I believe I've dealt with all the dll refactoring and namespace change issues but one.

In the Silverlight 3 project I'm using System.Project however System.Project is missing from the Silverlight 4 system.dll. Using Reflector I see that the following are missing from the Silverlight 4 system.dll:

IProperty<> IPropertyGetter<> IPropertySetter<> Property Property<> PropertyChangedEventArgs<> PropertyGetter PropertySetter

My question is, where do they live in Silverlight 4?

Thanks for your help!

Forgive me, the above should read:

"I'm using System.Property<> however System.Property<> is missing from the Silverlight 4 system.dll."

Thanks.
