I have a VS project with a Form and a Component. I have put my Component in the toolbox, and then added it into my Form so I can see it in the Component Tray of the Form. However, if I make changes to my Component that will produce errors when I compile my code, the Component disappears from the Component Tray. Further, after doing this I can not no longer drag my Component from the toolbox since the Designer can not find my Component until I make a succesful compilation. However, since the Component disappeared from the Form, I need to uncomment all code using the Component to achieve a succesfull compilation... Needless to say, this makes it quite cumbersome to develop my application. Is there a way not to have the Component disappear from my form (and toolbox) when my updated code does not compile (I would guess the problem is that the old version of my Component is erased at the start of the compilation)?
