Sorry for the late answer and potential solution, but I find it good to write down the solution I found. I ran into this problem (with VB project). The problem was caused when I put the label on the form and then I got some strange error ... I told VS (Community 2015) to ignore the error, because I was going to delete the element anyway ... but in the process, VS decided to completely split the Form1.vb file (it was muffled) and SAVE it when I never talked about it, to do this ...
The solution was to manually edit the Form1.vb file and restore what should have been there, which in my case was simple:
Public Class Form1 End Class
After making this change manually, I was able to open the project again, and the Design View was again available (by right-clicking). Again, Iām not sure why VS decided to save her working program after she caught some kind of error (what is the LAST that you would like to do when you get the error message!), But I assume that it simply means that I need to be more careful and make backups when I program to get around this crazy behavior.
