Problem with the ASP.NET 2.0 menu control and MCMS
A couple of customers reported problems when using the menu control with ASP.NET 2.0 and MCMS.
After analyzing one of the affected projects I identified that the reason for the problem is that the menu control seems to have a bug. It does not work correct if the following tag is included in the web.config:
<xhtmlConformance mode="Legacy"/>
Removing this tag resolved the problem for MCMS template projects and also for normal ASP.NET webform projects.
