How do I make buttons in two separate C# forms in two separate projects open each other?

Question

I am working with two C# projects in one Microsoft Visual Studios solution. One project contains a form used to select which form from the other project to open. I also have a 'Back' button on each of my Project 2 forms, which I hope to use to reopen the form selector from the first project. I have researched how to get around circular reference dependencies with no luck. I would prefer to keep these as two separate projects. Will I need to consolidate everything into one messy project, or is there a way to accomplish what I'm trying to do? Thank you in advance.

EDIT:

I found a simple, but effective solution. I only need to reference Project 2 from Project 1, because I can pass through the Project 1 form as a parameter into the Project 2 forms, then display the first form whenever a button is clicked. Thank you again.

Follow these steps:

1. Create a New Project (say 'Opener') in the same solution as a simple command utility.
2. Add the reference to the main projects to Opener.

3. In Program.cs add the following code:

   private static void OpenForm(String formName) { if (formName == "Form1") // Open your Form1 else // Open second Form2 }

4. Now you can just open the forms on the button click event click by:

   Process.Start("Opener.exe Form1");
