Out of the blue, I have started getting an assembly error when i try to debug my application. I am utilizing RadControls for WPF Q1 2010 in VS 2008:

Error 1 Could not load type 'Microsoft.Windows.Design.Metadata.ProvideMetadataAttribute' from assembly 'Microsoft.Windows.Design.Extensibility, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Line '1' Position '491'. C:\Documents and Settings\akedzier\My Documents\Visual Studio 2008\Projects\CCMB_WPF\WpfApplication1\panels\Panel_04.xaml 12 13 CCBM_Wpf

Here is the code it tags as problematic. It is almost verbatim from the Telerik example:

    
                        <ControlTemplate x:Key="NewGaugeBackground"  TargetType="{x:Type ContentControl}"> 
        
                            <Grid Width="{TemplateBinding Width}" Height="{TemplateBinding Height}"> 
        
                                <Grid.ColumnDefinitions> 
        
                                    <ColumnDefinition Width="20"/> 
        
                                    <ColumnDefinition Width="*"/> 
        
                                    <ColumnDefinition Width="20"/> 
        
                                </Grid.ColumnDefinitions> 
        
                                <Grid.RowDefinitions> 
        
                                    <RowDefinition Height="20"/> 
        
                                    <RowDefinition Height="*"/> 
        
                                    <RowDefinition Height="20"/> 
        
                                </Grid.RowDefinitions> 
        
                                <Ellipse Stretch="Fill" Grid.ColumnSpan="3" Grid.RowSpan="3"> 
        
                                    <Ellipse.Fill> 
        
                                        <ImageBrush ImageSource="pack://application:,,,/images/bronze.jpg" /> 
        
                                    </Ellipse.Fill> 
        
                                    <Ellipse.BitmapEffect> 
        
                                        <BevelBitmapEffect BevelWidth="20" 
        
                                            EdgeProfile="BulgedUp" 
        
                                            Relief="0.5" 
        
                                            Smoothness="0.3" /> 
        
                                    </Ellipse.BitmapEffect> 
        
                                </Ellipse> 
        
                                <Ellipse Grid.Row="1" Grid.Column="1" Stretch="Fill" Fill="White" /> 
        
                                <Ellipse Grid.Row="1" Grid.Column="1" Height="48" Width="48"> 
        
                                    <Ellipse.Fill> 
        
                                        <ImageBrush ImageSource="pack://application:,,,/images/bronze.jpg" /> 
        
                                    </Ellipse.Fill> 
        
                                    <Ellipse.BitmapEffect> 
        
                                        <BevelBitmapEffect BevelWidth="5" 
        
                                            EdgeProfile="BulgedUp" 
        
                                            Relief="0.5" 
        
                                            Smoothness="0.3" /> 
        
                                    </Ellipse.BitmapEffect> 
        
                                </Ellipse> 
        
                            </Grid> 
        
                        </ControlTemplate>

This has compiled and run just fine previously. Not sure what changed to cause the error.

Hello Art,

I am sorry to hear about your difficulties while using our controls. Please login to your account and download the following zip:
http://www.telerik.com/downloads/productfiles/bacdb/VS2008_Design_Assemblies.zip

Using these design assemblies with Q1 2010 should fix the problem. If this does not work try to upgrade with our latest internal build. If the problem still persists I would like to ask you to open a separate support ticket and attach there a sample project which demonstrates the problem to test it locally and provide you with further assistance.

Regards,
Andrey Murzov
