When I want to edit/view the code for a winforms control/form i created, I need to right-click in the solution and select "view code". The default action for opening the file is "view designer". This appears to be the case for any C# file containing a class that inherits from a winforms control, even if this is indirectly.
The daft thing is that VS does this if it can't run the designer (for instance when the control is not the first class in the file).
Is there hint or attribute or workaround to stop VS from doing this?
- Right-click on a file in your solution
- Select "Open With..."
- Select "CSharp Editor"
- Click "Set as Default".
(In a web application, you need to select "Web Form Editor")
Decrotate your Form or Control that should open in code view with [System.ComponentModel.DesignerCategory("Code")]
