I'm using the commands in the RadWizardCommands class as described Commands page of the documentation for the RadWizard. I'll start by noting that everything works in the application at runtime; however, at design-time Visual Studio 2015 reports the use of the commands as errors. I'd love to eliminate this noise, because it's easy for it to obfuscate real problems.
<telerik:RadButton Content="< Back" Command="wizard:RadWizardCommands.MoveCurrentToPrevious" .. />
The errors that are reported are: Invalid value for property 'Command': 'Microsoft.VisualStudio.DesignTools.XamlLanguageService.Semantics.XmlValue'
