I've done a couple of type converters and am now thinking about trying a UITypeEditor. None of this code needs to be distributed though, so I'm thinking about putting it into an extentibility project. However, I'm unclear how references/distribution work. I know that it can be done, as SF does this...just not sure how. How does this work? (The referencing of an extensibility project so it's available at design time, but not required to be distributed.)
