Just open your project in VS 2008 and it will be converted. After it's done you should check the targeted Framework in the project properties make sure it's 3.5. If it's not you can simply change it there.

The code should mostly work as is, although you're likely to get several warnings and possibly some errors. The warnings won't prevent the project compiling but you should address them anyway. Most will be quite simple. Some may require using different types or members as the old ones may have been deprecated.
