Vista - type not defined when wiring events in xaml

hello

i am getting error "type VisualAMS.Welcome is not defined", when building,
this error only occurs when i enter a name for the class either through blend
or via the xaml otherwise it builds fine but i cannot wire events via
controls created in expression blend. Using vb.net 2005 with the relevant
..Net 3.0 sdk etc, Expression Blend 1. This project was created from scratch
based on the Family.Show app.
Have tried everything, remove the name of the control and it builds fine,
add it back in and the error returns, don't understand why...

Enclose the following code, can pm on westy@xxxxxx and i can provide
a zip with the project files otherwise general files are below

thanks in advance

I appear to have the same problem. However it works when written in C#. I am converting the OutlookUI HOL tutorial to VB.Net and have run into this problem of code not compiling when x:Name="foo" added to UserControl that has triggers.
Has anyone found a solution?
