After adding the reference component in the Toolbox, the following error occurs when trying to use the component:
"A reference to "GMap.Net.WindowsPresentation,Version=1.6.0.0, Culture=neutral, PublicKeyToken=b8b9027b614afef" has been added to the project. In rder to use types from the new reference,press OK to restart the XAML designer. After the XAML Designer restarts, re-create the control on the artboard."
Already restarted Visual Studio, but not resolved.
