Hi, I have seen that before, but what I am trying to avoid is having the rules hard coded into the code. It means a code change and recompile to every rule change.I guess I am looking for xml configuration. I know there is http://www.agilepartner.net/oss/nxbre/. I think it is written in .NET 1.1 (we are using 2.0) and may seem a bit heavy for what I am trying to achieve. [EMAIL PROTECTED]
