TypeLoadException on generating help text

Hi there,

a customer of ours gets this stack trace when our application is starting, and we are not able to determine whats going on. I traced it back in the source code to the first reflection call to getting a license attribute out of the executing assembly, but since our application is crashing immediately with no output I have to rely on whats event viewer has. And event viewer unfortunately does not tell me which type could not be loaded and why. Any ideas might be helpful:
```Application: App.exe

Start at CommandLine.Infrastructure.ReflectionHelper.GetAttribute and follow the call path through CommandLine.Text.HelpText.AutoBuild and Parser.DisplayHelp, using the stack trace as the entry point. Reproduce the startup failure if possible and identify which type or assembly attribute cannot be loaded and why; a useful outcome would be a confirmed cause and a narrowly defined fix or diagnostic improvement.
