Hi,
in my WPF app, i have Infragistics Gallery button in the ribbon control. This gallery has different set of layouts for the application. So when I select one of the layout, the application should change to that layout. This works most of the time, but occassionally, this crashes with a null reference exception. But when i look into the dump file, the dump shows only the microsoft call stack. Can someone help me how to figure out what the issue is when the stack does not contain any of the application code.
Below is the call stack.
