    Error 2 Cannot create an instance of "TreeView". C:\tfs\GenOn\MyControls.Controls\MyControls.Controls.xxxInformation\xxxInform.xaml 29 13 MyControls.Controls.xxxInformation

        x:Class="MyControls.Controls.xxxInform"
        xmlns:telerikInput="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.Input" xmlns:telerikgrid="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
        xmlns:my1="clr-namespace:MyControls.Controls;assembly=MyControls.Controls.TreeView"
        xmlns:my3="clr-namespace:Telerik.Windows.QuickStart.Animation;assembly=Telerik.Windows.QuickStart"
                 xmlns:ViewModels="clr-namespace:MyControls.Controls.ViewModels"
        xmlns:Globalization="clr-namespace:System.Globalization;assembly=mscorlib" mc:Ignorable="d"> 
           <Grid x:Name="LayoutRoot" Background="White"> 
            <Grid.ColumnDefinitions>

                <ColumnDefinition Width="5"></ColumnDefinition> 
                <ColumnDefinition Width="710"></ColumnDefinition> 
                <ColumnDefinition Width="700"></ColumnDefinition>

            <Border  BorderBrush="Black"  BorderThickness="2" > 
                <my1:TreeView x:Name="trvTreeView" Margin="0,5,0,0"/> 
            </Border> 
    <!-- Further details elided -->
    The line <my1:TreeView x"Name="trvTreeView" Margin="0,5,0,0" /> is where the error occurs. Sometimes I can fix this by Rebuild All. Sometimes I have to delete generated code. Is there a way to fix this for good? Is it a bug in Visual Studio?

    Hi Ralph,

     This could be a name-related problem since the tree in the Silverlight Framework is also named "TreeView".
    Could you please try to rename your tree to something different from RadTreeView and TreeView and let us know if this helps?

    Best wishes,
