I've been creating a Windows Form App in Visual Studio 2015.
It was all going well until I closed the tab titled "Form1.vb [Design]" which showed the form and all the controls.
There is no error but I now seem unable to access the design view.
I added a second form to see if that did anything and notice that it has a different icon. The new form has a little icon of a form with controls whereas the original form just has the letters VB in the icon.
The code all seems to be there and it builds successfully with the form visible when running.
