Are there good third party EDMX generator/updater tools out there? The visual studio EDMX is driving nuts. I constantly have to restart VS2008 in order to get the EDMX to properly update.

I would like to make some changes to my EF4 edmx file without modifying the file itself, mainly so I don't loose all my changes if I regenerate the model from the database. I'm familiar with XSL and have seen references made to using it in conjunction with the edmx file. This sounds like a great solution, however I can't seem to find any...

This 3rd table has an extra field besides the two keys required, so that Entity Framework transforms it into a full entity rather than a many to many relationship between the other 2 tables. I cannot change this third table i...
