I don't want to use .NET4.0 directly in Visual Studio 2008, ...
The wired problem is, in VS 2008, everything works fine. In VS2010 while serializing, it is missing the "ReportDimensionElements" so I'm unable to get the values back from the serialized value back from the XAML.

Okay, so the good old System.Web.Caching.Cache (which is, by the way, still there in .NET 4) has the ability to set so-called CacheDependency objects to determine whether a cached item is expired or not. One can also specify custom logic for determining whether a cached item is still useable o...
