My strategy was to keep the project's layout clean. Given that this is a datalayer project, and I'll have a class file for each concerned entity, I thought I would put the .dbml into its own directory. It turns out that locating your .dbml file within a subdirectory turns it into a lower level namespace of sorts.
This is a C# class library project.
Any hints where I could turn this functionality off, and get access to the LinqToSql dbml datacontext name without having to type the directory name to get access to the actual LinqToSql classes?
