Design-Time validation of library

I have a library that I would like to license and distribute.

I know how to license a class/library for runtime. I've done that several times, actually. I know how to license a user control. I've also done that several times.

What's got me stumped is how to license a library (that has no drag/drop user control or component) for development only. How do you license a library for design-time?

Any thoughts/hints?

From stackoverflow

• I finally found the answer. This one isn't as apparent as I thought it would be.

  Instead of looking for DesignTime or RunTime attributes, you need to see if a debugger is attached.

  Drop this in the constructor (with the appropriate attributes on your class), and you're off and running!!

  if (System.Diagnostics.Debugger.IsAttached)
  {
      License L = LicenseManager.Validate(typeof(MyControl), this);
  }
  

  I hope this helps someone else with the same issue!!

• You could use LibraryManager.UsageMode to determine if you are running at design time. I assume you wish to check for a debug run also from the answer you posted.
