  Created a WPF Control library that uses ComponentOne elements (FlexGrid, C1Checkbox, etc)

  I have a separate application project which dynamically loads the WPF Control library .dll using ‘System.ComponentModel’

  When instantiating my control class, I get the following error:

  [code]
  
  System.Windows.Markup.XamlParseException: ‘The method or operation is not implemented.’

  Inner Exception:
  
  NotImplementedException: The method or operation is not implemented.[/code]

  Hi,

  You have marked the post as answered. Could you please confirm if this issue is resolved?
  
  If not, then please share more information like a screenshot of Error List and StackTrace.
  
  Usually, this issue occurs, if there’s an error on the XAML code. And it would be helpful if we have more information to resolve this issue.

  Hi Nitin,

  A workaround I found was to manually load the C1.WPF.Core.dll to into memory at program startup.

  public MainWindow()
  {
  	InitializeComponent();
  	Assembly.LoadFrom("C1.WPF.Core.dll")
  
  	var configuration = new CompositionContainer(new AssemblyCatalog("WpfControlLibrary.dll"));
        	var getUserControl = configuration.GetExport<IGetWPFControl>() 
  
  	this.MainGridControl.Children.Add( getUserControl.UserControl );
  }
