Sharing code between 2 projects without a dll

Question

How can I have code-sharing between two projects without making a dll?

The issue is: I have a tool that syncs users & groups from LDAP to a database.

Answer 1

How about hand-modify the project files to point to the same source file?

Another option - put both projects in the same folder. Add a class to one, then in the other project add existing class and point to the class just created.
