You must be using Silverlight code on WPF? Kindly see XMLNS on this page. http://msdn.microsoft.com/en-us/library/system.windows.controls.control.aspx

hello

i have a blue squiggly line on xmlns:common="clr-namespace:System.Windows;assembly=System.Windows.Controls"

it is not a design-time error. i have close the xaml-file when i build the project.
but, i have this error when i open the xaml-file in the design-view.

the errormessage is: "Die Assembly "System.Windows.Controls" wurde nicht gefunden. Alle Assemblyverweise müssen vorhanden sein, und das Projekt sowie alle referenzierten Assemblys müssen erstellt worden sein."

i think, the error is about the assembly reference. but, i can't found an other.

What error message are you getting exactly?

If you are getting the blue squiggly line on VisibleLayers with this error:Unable to cast object of type 'Microsoft.Expression.DesignModel.DocumentModel.DocumentPrimitiveNode' to type 'Microsoft.Expression.DesignModel.DocumentModel.DocumentCompositeNode'.

this is known design-time error that appears when you have XAML open.

Since you say the error includes "System.Windows.Controls" I cannot think of an error related to this that shows with "VisibleLayers" property set. I think it would help if you share the actual error message and code so we can reproduce it here too. Thanks!
