I've created a custom TypeConverter to be able to showvalues in a Combobox on a wizard page.
It works great!
But, after the concept was proven I added some logging using Debug.WriteLine.
Immediately the Combobox showed a red exclamation mark on clicking on the arrow.
Using the debugger I found out that the logging code cause this, but there was no error at all.
The method just returned like there was an exception and the red exclamation mark said "Invalid value".
After removing just the Debug.WriteLine it worked fine again.
Can someone explain this behaviour to me?
