I'm trying to create a simple Guestbook web service using ASP.NET WebServices.

When trying to serialize a list of objects, I get the following exception:

System.InvalidOperationException: The type of the argument object 'GuestBookService.GuestBookEntry' is not primitive.

How can I fix this error?

One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
