How to modify .rules files without compileing entire workflow assembly?

Question

I have a situation where I need to update/edit/delete rules in .rules file. without re-compileing my workflow assembly.

I tried to make .rules file as a 'Content' of my workflow project instead of 'Embedded Resource'. However, the compliler is giving me the compile time error stating that the RuleSet is not defined.

Activity 'policyActivity1' validation failed: Can not find the rule set "RuleSet1". Check if rule set is defined in the rules file.

If I make the .rules file as an 'Embedded Resource' the error disappers. But, not when the .rules file is 'Content'.

Any Suggestions/comments/concerns?
