Hello,

I'm having a problem with a mixed managed/unmanaged DLL.  When I
attempt to reference "Exception" in my VB.NET code, it conflicts with
some other "exception" that gets somehow gets into the assembly.

This code reproduces the issue:

#using <System.dll>
// #include <vector> is in stdafx.h
#include "stdafx.h"

namespace ExceptionClash
{
    public __gc class Class1
    {
    public:
        System::String* SayHello()
        {       
            return S"Hello";
        }
    };
}

And then, ExceptionClash.Class1 is used by this VB.NET code:

Imports ExceptionClash

Public Class Test
    Public Shared Sub Main()
        Dim o As New Class1
        Try
            Dim s As String
            s = o.SayHello()
            Console.WriteLine(s)
        Catch ex As Exception
            Console.WriteLine(ex.ToString())
        End Try
    End Sub
End Class

The error I get is upon compilation of the VB.NET code:

C:\temp\ExceptionClash\Debug\test.vb(14) : error BC30392: 'Catch'
cannot catch t
ype 'exception' because it is not 'System.Exception' or a class that
inherits fr
om 'System.Exception'.

If I view ExceptionClass.dll in ildasm, I see a type "exception" in
the root namespace.  This is conflicting with System.Exception in
VB.NET.  It seems to only happen when #include <vector> is in
stdafx.h.  I am not sure where this other "exception" class is coming
from.

I can work around the issue by not using "Imports ExceptionClash" or
by specifying System.Exception instead of just Exception.  But, I'm
looking for some understanding or a resolution as opposed to a
workaround.

Does anyone have any insight into this issue?  

Thanks in advance,
Chris
