Composite UI Application Block - Thread Safe

Does anyone have any input on setting up my CAB application so that the
application is thread safe, and cached appropiately? I read that this
can be managed through Services, and dynamic injection. On the
contrary, I was told that this can be handled using Enterprise Library
cached application block. Last, but not least, i read you can implement
this at the class level, creating immutable classes, and caching them
accordingly. Any suggestions would be greatly appreciated?
 
All UI operations must be carried out on the UI thread. Therefore you
still need to make the distinction in CAB whether the operation is a
graphical one or not.

A service dependency for example may work well on some other thread but
a UI operation will not.

CAB only connects up the various parts of the application. Those parts
all need to respect the basic principals.

Thanks for the comment. What would you say about the following
description:

I would like to pull data from a data layer, and keep that
information cached so that you don't have to make repeated calls to
the data base. From the little research I have done so far, and from
what you described to me, it seems possible to keep the information in
the ui thread, and use CAB's service to pull data from the data layer,
populate a view or module, simply use that instance in a workitem,
where it can be passed around accordingly. However, if this can't be
done at the ui level, then i thought about using the cached
application block provider from enterprise library at the data access
layer.. Do you see anything wrong with this?

THanks..
