What is the best location for solution file in Visual Studio?

Question

I prefer for the solution file to be in the same folder as the project files in Visual Studio. I know this is accomplished by unchecking the "Create directory for solution" checkbox. However, VS 2008 defaults to having the box checked.

I am interested in other people's opinions on whether the solution file should live in the same directory.

Answer 1

When a solution contain more than one project, I like a solution file in a parent directory and the project files in its child directories.

When a solution contains many projects (my current solution has 36 projects/assemblies), then I'll have:

• Grandparent: solution
• Child directories: "solution folders" which are logical collections of projects
• Grandchildren: the projects themselves

Answer 2

I prefer it something like this:

MyProject
  src
    Domain
    Application
    Infrastructure
    UI
  solutions
    MyProject
    Infrastructure
    Domain

Solutions folder contains solution folders. All projects are referenced from src folder.
