System.Windows.Data Warning: 40 : BindingExpression path error: 'IsChecked' property not found on 'object' ''RibbonMenuButton' (Name='')'. BindingExpression:Path=IsChecked; DataItem='RibbonMenuButton' (Name=''); target element is 'RibbonToggleButton' (Name='PART_ToggleButton'); target property is 'NoTarget' (type 'Object')
the above exception thrown when we use System.Windows.Controls.Ribbon.RibbonMenuButton ,it bothers me, we want to get rid off.
thanks in advancd,
we use VS2019(Version 16.8.2) Wpf .NetCore3.1 App.

If the warning does not affect the operation of the project, then we can generally ignore it; if it affects your project, could you please share with us the Build settings page of this project (right-click the project->Properties->Build) and some code snippets that can reproduce this problem?
