Your boss has trust issues. Two bits of advice:
1) Have your boss consult a lawyer to make sure that legal agreements with
vendors and contractors are solid and can work in your company's favor in
the event of the exposure of a trade secret.
2) Create a build server that builds your app every day. Take a look at
NAnt or NMake to automate the build. Create a script to automatically copy
the results of the build to a share that allows specific access to the
employees who need it. Now, folks who need to refer to the code do not have
direct access to it.
Note that #2 is a partial victory at best. You create three issues: (a) a
loss of efficiency since a developer cannot see the code he or she is
calling, making it more difficult to use the code, (b) a sense among the
staff of distrust, which engenders resentment and lowers productivity, and
(c) no real protection of trade secrets since a developer who knows what
module the trade secret lives in can decompile the module. Of course, you
could run the code through an obfuscator during your nightly builds. This
buys you a little but not a lot.
3) Partition your systems so that key logic is only created and maintained
by internal, trusted, staff members, while other, less sensitive, work is
performed by consultants and vendors.
In Microsoft IT, we make use of consultants and vendors all the time. We
rely on #1, make use of #3, but rarely if ever use #2. No one wants to work
in an environment where they aren't wanted.
HTH,
