Usually, one scope is created per form/window. Entities pinned to the scope (marked as needed) are not evicted from the cache until the scope is disposed or collected by the garbage collector.
This class is a base class for platform-specific scopes, such as C1.Data.Entities.EntityClientCache (Entity Framework) and C1.Silverlight.Data.RiaServices.RiaClientCache (RIA Services).
