Showing Namespace not resolved.

Question

Probably a simple problem but I am showing XAML Namespace  not resolved as follows.
XAML Namespace http://schemas.microsoft.com/expression/blend/2008 is not resolved.
This will not let me build the project to view.

Here is the XAML:

<UserControl x:Class="Microsoft.EDD.Max.Silverlight.LicenseManagement.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:controls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls"
    xmlns:QuickStart="clr-namespace:Telerik.Windows.QuickStart;assembly=Telerik.Windows.QuickStart"
    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView"
    xmlns:gridview="clr-namespace:Telerik.Windows.Controls.GridView;assembly=Telerik.Windows.Controls.GridView"
    xmlns:riaControls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Ria.Controls"
    xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"
    xmlns:ds="clr-namespace:Microsoft.EDD.Max.BusinessServices.RIA.Web;assembly=Microsoft.EDD.Max.BusinessServices.RIA"
    xmlns:riaData="clr-namespace:System.Windows.Data;assembly=System.Windows.Ria.Controls" Foreground="#FF506266"
    >
    <UserControl.Resources>

Thanks for any insight you might have

Answer 1

I just had this happen -- It turns out that Blend 4 took out the "mc:Ignorable=d" when I added a user control to the page.

Answer 2

Found couple of solutions that finally works:

1. http://www.laumania.net/post/A-possible-solution-to-the-error-e2809cXAML-Namespace-httpschemasmicrosoftcomexpressionblend2008-is-not-resolvede2809d.aspx

2. Solution must require to have "Debug" configuration. If projects has its custom configuration, keep the default Debug configuration available, although it doesn't require.

I provide a more complete explanation of this and actual code samples on my blog article entitled:
