wpf user control - prevent code in constructor from running in designer

[moondaddy]

using VS 2008 sp1 and c#, I have a user user control (uc1) which uses
another user control (uc2) in its xaml. When I compile the application and
then view uc1 in the designer, I get the error screen "Problem Loading" and
a blue squiggly under the reference to uc2 in the xaml and the tooltip for
the blue squiggly says "The type 'uc2' was not found...".

In the constructor of uc2 I have replaced the old exception handling with
some new exception handling and this problem began when I started using the
new exception handling. evidently id doesn't like the new exception
handling code/libraries. So I put the following line of code as the first
line in the constructor thinking that it would fix the problem, but it didn't:

if (DesignerProperties.GetIsInDesignMode(this)) { return; }

using this line in the past has helped with other issues in the past such as
preventing code from attempting to connect to a database when viewing
controls in the wpf designer. Can anyone please advise how I can proceed in
trouble shooting this?

everything works OK when I rem out the exception handling code. We've made
a huge investment in the exception handling framework and it needs to stay.

Thanks.

I would guess you need a xmlns reference to whatever code you're on about
with "new exeption handling framework."

Where is said code?

Both uc1 and uc2 are in the same assembly 'UIControls' and the exception
handling are in a different assembly (Ifx), however, the old exception
handling code was in it's own assembly as well and I never had this problem
before, therefore, I don't think I need to reference Ifx in the xaml. Does
this answer your question? any other ideas?

Thanks.
