>Yes, that worked. It's funny since I have subclassed mmAppConfiguration and have a custom config in my application that I have been able to update. I incorrectly assumed that the WriteKeysToConfig() method knew about the default application configuration file and I did not need to pass the file name. I know, never assume. Once I passed the file name, it saved properly.

You are more than welcome. I am not aware of anything, but it would be worth while opening up the MM Framework solution and looking at those classes to see what all is in there. I would suppose for something like that (although risky for a user to enter a connection string) you could put in properties for extra things and then give the user a UI to add some things. Would take a bit of work to validate and use stuff they add like this however.
