C#: form in project not showing up in intellisense

I have created a form in a project. The new form is listed in the solution explorer as being in this project.

But the form is not showing up in the intellisense listing when I try to create an object variable in order to show the form.

Is there something els开发者_高级运维e that needs to happen after you add form to a project?

You may want to check that your forms are in the same namespace?
