Anyone that is working frequently with either LINQ to SQL or the Entity Framework needs to go get a copy of the Huagati DBML/EDMX tools. They plug right into Visual Studio (2008) and allow you to perform many of the tasks that you would think VS would do for you. I just recently had a new dev db get corrupted. I had no backups for it. I also had no scripts generated for it. Argh! What to do? With this tool I was able to reverse engineer my EDMX file and spit out all the SQL I needed to generate the database. There are many other features provided with this tool that I am sure you will love too.
This tool is offered in a free 30 day trial. Then there are a few paid versions. I think that the professional version is worth the $120 price tag but there is a $50 version and a $12/mo subscription option. Very good stuff! Go grab a copy.
