In my solution, I have a lot of projects which use project references to other projects in the solution. How do I figure out which projects reference a particular project?
A feature in Visual Studio exists for this. Right-click on your solution and click "Project Dependencies". Select the project that you want to find which other projects depend on it in the "Projects:" drop down list. Any projects that depend on the selected project will be unchecked and grayed out because checking them would cause a circular dependency.
