WPF: Microsoft_Windows_Themes not found

themeswpf

I am getting this error in my WPF app:

The type 'Microsoft_Windows_Themes:ScrollChrome' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built.

Any idea?

Make sure you add this reference in the top most tag of your control/page/resource dictionary/whatever:

...

xmlns:Microsoft_Windows_Themes="clr-namespace:Microsoft.Windows.Themes;assembly=PresentationFramework.Aero">

And add a reference to PresentationFramework.Aero in your project.

Written Instructions:

Right click on the solution and click Properties.
Click Configuration on the left.
Make sure the check box under "Build" for the project it can't find is checked. If it is already checked, uncheck, hit apply and check the boxes again.
(Optional) You had to do it for both Release and Debug modes on the solution properties.

Wpf – RibbonCommand was not found

If you are using the new Microsoft WPF Ribbon, the RibbonCommand type has been removed. The Command property is now an ICommand type.

To set the command on a RibbonButton, you can do the following:

<ribbon:RibbonButton Command="ApplicationCommands.Copy" />

or use any command that implements ICommand.
