I stated a question about Web Service Issues earlier, but I wrote the
question poorly.  I started a new thread to explain myself better.  

Say that there are 2 developers that are developing Web Services from within
the same project (which links to a web site hosted on our development server).

Programmer 1 makes a change to an existing Web method and builds the project.
Meanwhile, Programmer 2 also has the same project open and he makes a change
to a different Web Service in the same project.  He then, builds the project,
but at that point his cache doesn't have the latest code for Programmer 1 and
so it overwrites the file with the one from his (Programmer 2's) cache.

At this point, Programmer 1 has lost any changes (on the server, not locally
in his cache) to what he had just changed.

We believe this is a Cache issue.  We just don't know where to take care of
this.  What's the best way to take care of this?  

Is there any way around this issue?
