I just published my latest article about an issue I had no later than last week.

I wanted to use a generic form but the designer (very useful in Windows Forms) was always reporting a strange error even if the compilation was not reporting any issues.

If you ever tried, you surely had the issue.

If you never tried, read on, this is a great feature and the workaround to make the designer is really easy!
