C# 2008 projects share a database file

Question

For a C# 2008 desktop/console application I want to share a linq to sql (*.dbml file) between 2 different proejct files in the same solution.

I know that I should probably put the linq to sql (*.dbml file) in its own project file with a class libary?

Since I do not know how to accomplish this goal, I am wondering if you can point me to a reference on how to accomplish this goal?
