Go to Definition finds base class method, not override class metho

Hi,

I have a question about how "Go to Definition" works in VS.  I have this
situation...

If you select a method call for a an object where the class defines an
Override of a base class defined method, and then select "Go to Definition"
in the context menu, in my system (VS 2005 - Visual Basic 2005), system shows
the definition as being in the Base Class instead of the derived class.  Is
this just a feature of VS, or is something else going on?

I've debugged the code and the proper version of the method gets called, but
I can't think of why VS wouldn't show the definition for the derived class
method instead of the base class when you ask it to "Go to Definition".

Any ideas why this is so?

No, I don't think so. I have performed some tests on this problem, but
cannot repro this scenario. With the following sample code, If I issue the
"Go To Definition" command at the last code line, the VS2005 text editor
will be navigated to the definition of the 'Register' method in the 'Boat'
class, not the Vehicle's:

Public MustInherit Class Vehicle
  ...
   Public Overridable Sub Register(ByVal owner As String, ByVal modelDate
As DateTime, ByVal originalCost As Decimal)
       ownerValue = owner
       modelYearValue = modelDate
       currentValueValue = originalCost
   End Sub
End Class

Public Class Boat
   Inherits Vehicle
   ...

   Public Overrides Sub Register(ByVal owner As String, ByVal modelDate As
DateTime, ByVal originalCost As Decimal)
   ...
   End Sub
End Class

..
   vessel = New Boat()
   vessel.Register(ownerName.Text.Trim, New Date(CInt(modelYear.Text), 1,
1), CType(currentValue.Text.Trim, Decimal))

Maybe your project is different from mine, would you please provide a small
self-contained sample for us to research, we can use the code snippet to
repro the issue.

Thanks!

Best regards,
