Couple of questions:

• Is this a runtime or a design-time issue? So, does this exception happen when you start the up or when you are trying to add the new control to the Form?
• Just to make sure, I understand the scenario: Why do you need to call those methods in constructor?

Thanks!

• It's a runtime issue, so this exception occurs when start the project.
• This exception does not occur when call those methods in Form load event or other control events.

@lonitra Sorry for the delay.

• I encountered a runtime issue when trying to start up the application.
• We are using these methods to retrieve assembly types and then create a custom XML serializer based on these types within our application.
