Perhaps I misinderstnad your question. My app has two parts.

One - business logic, compiled locally by me and placed in bin directory of
web site on shared hosting machined.

"Skins" consisting of ASPX's/ASCX's on remote machine. It is my
understanding that each time the ASPX's are changed, the site modified, the,
the JIT compile funtion of DOT/NET takes over and a new dll is created.

BTW, it appears that this also happens in IIS after a restart, causing the
first load of ASPX-based apps to be characteristically slow.

When I do standard FORMS/based authentication, I get Security Exceptions
thrown off by MSCORLIB. MSCORLIB is being asked about the current
authetication state by the precompiled "LOGI" DLL. It is my understanding
that is addressed by using a SNK file, generated in the usual way before the
DDL is ever deployed.

The probelm is that "On-The-Fly" DLL. I can't seem to prevent it. It is
compiled on the fly after each change. It does not like the new SNd DLL.
- Do I need to tell that new App to trust the new StrongNamed DLL?
- IF so, should this be by reference to the "Public" key only (well
probably).
- How do I refernece that Public Key, then, in the remote compile?

Hope this is clearer.
