Putting the whole thing into a file, works... Perhaps a reference
(1->3) is missing...
Let me know...

Instance of derived class does not show public methods or properties that are not in the inherited class

What is happening is that I have a class (ClassA) that inherits a class
(ClassB) which inherits System.Net.Mail.MailMessage

Project 1 references Project 2,
Project 2 references Project 3.

When I declare an instance of "ClassA" in a thrid project I get all of the
public methods/properties that are in the System.Net.Mail.MailMessage class,
but I do not get any of the public methods or properties that are
specirfically declared in Class B

Has anyone seen this before or could help me along in this situation?
Thanks...

I am using VS.NET 2005.

PROJECT 3
=========
Public MustInherit Class EmailMessage_Base

Inherits Project3.EmailMessage_Base

Reference project 3 in project 1 or set up an override and call base in
Project2.

Could you explain what the logic behind this is? Or help me understand...

Why would Project 3 have to reference Project 1? If it is inheriting,
shouldn't Project 3 be able to use all the members that the class in Project
2 is inheriting already?

Looks like referencing is not "transitive" (like inheritance). It's
more just a matter of scope...
Perhaps since you had in mind the idea of inheritance you were kind of
extending it also to references, but as you have demonstrated, the idea
does not seem to apply...

In VB.NET 2005 Express Edition I get an error message stating I need a
reference to Project 1. The help states that this is needed to avoid ambiguity
in case the class is defined in more than one dll or assembly. I am not sure
what they mean by that, but prefer the error message over the strange
behaviour that was described.
