 - Use `using (Computed.Invalidate()) { ... }` block to invalidate a result of a certain call (and thus all of its dependencies) or a set of them. Here is how it looks like:

 Finally, such clients act as "regular" Fusion services - the results they produce are also backed by [computed values], so they extend the local dependency graph the same way. Look at this code:
