Question

Should the folders in a solution match the namespace?

In one of my teams projects, we have a class library that has many sub-folders in the project.

Also, note that if you use the built-in templates to add classes to a folder, it will by default be put in a namespace that reflects the folder hierarchy.

The classes will be easier to find and that alone should be reasons good enough.

The rules we follow are:

• Project/assembly name is the same as the root namespace, except for the .dll ending
• Only exception to the above rule is a project with a .Core ending, the .Core is stripped off
• Folders equals namespaces
• One type per file (class, struct, enum, delegate, etc.) makes it easy to find the right file
