using metal sql with an existing project
===

I am working on a project that the previous developer lost a contract on. They have used linq thoughout for database interaction. I need to add various fields to the existing db inserts ect, but I'm not certain how to rebulid/refresh the linq source code.

I've heard sql metal may provide a solution beyond manually editing the files (some of which I'm struggling to even locate), but I'm concerned that if I do regenerate files this way I might break something.

The db consists of tables and views, as far as I am aware.

Please let me know what db details I should provide (I'm not really sure)

Basically, does anyone have a good tuturial for regenerating selected tables into c#.net source code (I have looked but the examples I've found are all over complicated), and more importantly what pitfalls should I check for?
