Hi Ricardo,

Query 1: Exception was thrown when configure the Application menu.

We are unable to reproduce the issue from our end. Please refer to the attached sample for your reference.

Could you please share the following details.

• Theme name, if you are using a Theme.
• XAML and C# code of ribbon
• If possible, please share the modified demo.

Query 2: How to change the header of the application menu.

We suggest you to use the “BackStageHeader” property instead of “ApplicationMenuHeader” property to change the header of the application menu.

Hi Ricardo,

To apply a theme globally in an application, set the ApplyStylesOnApplication property to True. It merges all the theme resource files to Application.Current.Resources. Please refer to the attached documentation for your reference.
