beta1->beta2 problem - XAML base class

06-27-2008 12:31 AM |

Hey Everyone,

I'm trying to upgrade my B1 project to B2 --

In B1, I had defined a base class for my XAML classes --

namespace MyApp.Screens

{

    public class FormBase : UserControl

    {

        public FormBase ()

        {

        }

    }

}

And my XAML / XAML.cs files declared like so:

-------------

namespace MyApp.Screens

{

    public partial class Test : FormBase

    {

        public Test()

        {

            InitializeComponent();

        }

….

----------------

<FormBase x:Class="MyApp.Screens.Test"

    xmlns="http://schemas.microsoft.com/client/2007"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"

    xmlns:extSL="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Extended"

               >

    <Grid x:Name="LayoutRoot" Background="Transparent">

        <Grid.RowDefinitions>

….

In beta 2, I always get this error when I try to instantiate my control from code:

Test test = new Test();

Exception:

XamlParseException - Unknown element: FormBase [Line: 6 Position: 16]

The base class has no code (just a public ctor) or XAML.

Can anyone give me a clue here… ?

Thanks --

Thanks Leonid -- I should have tried that instead of posting the question - it was next on my list
