Updating the cache is a pure client-side operation.  It is essentially the same whether you are running a Silverlight, WPF, or WinClient application.  Get the value from webserver and stuff it in the cache.  You should be able to find some examples in the Learning Resources on Disconnected Use,

If I have an instance of an entity Person called ‘person’ on the Silverlight side .. how do I ask it to refresh itself now.

Just that instance.

 

Can't figure it out from the documentation.

This is not as obvious as it should be.  We will be reviewing the signatures for RefetchEntitiesAsync.  In the meantime, the code should look like this:
 
      var list = new EntityKeyList(typeof(Person), new EntityKey[] { somePerson.EntityAspect.EntityKey });
      entityManager.RefetchEntitiesAsync(list, MergeStrategy.OverwriteChanges, RefetchCompleted, null);
 
...
 
    void RefetchCompleted(EntityQueryOperation e) {
      // Do stuff
    }
