Hi ,

Can anyone help me how to fix this error..?
Parser internal error: Object writer 'xClassNotDerivedFromElement'.

This error dispalys when i execute line below (Silverlight 4)

myContent.Content = New SilverlightApplication1.MainPage

Here I am Trying to load a file   MainPage.xaml (c# file) from file   test.xaml(.net file) using content holder
as below

    <ContentControl x:Name="myContent"   HorizontalAlignment="Center"      Height="554" Width="576" >
            <ContentControl.Content   >
                SilverlightApplication1.MainPage
            </ContentControl.Content>
        </ContentControl>

Both files    MainPage.xaml(c# file) and   test.xaml(.net file)   are under one solution SilverlightApplication1

Thanking you.
Chethana

If you google this error message, you'll find that some Silverlight developers have experienced this when they miss to define namespace.
