The Tag 'RadDataServiceDataSource.DataSourceContext' does not exist in XML namespace

[Jeff]

Hi,

I just installed RadControls for WPF v2012.3.1017.40.  I have VS2012 v11.0.50727.1 RTMREL and I'm targeting .NET 4.0.

I'm getting the following error when referencing RadDataServiceDataSource:

Error    1    The tag 'RadDataServiceDataSource.DataSourceContext' does not exist in XML namespace 'http://schemas.telerik.com/2008/xaml/presentation'. Line 55 Position 22.    D:\SVN\branches\DataExtractor-2.0.x\Workbench\MainWindow.xaml    55    22    Workbench

Here is the XAML in question:

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:myvm="clr-namespace:SmartProcure.Workbench.ViewModels"
        xmlns:mycv="clr-namespace:SmartProcure.Workbench.Converters"
        xmlns:mdmhub="clr-namespace:SmartProcure.Workbench.MdmHub"
        xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
        x:Class="SmartProcure.Workbench.MainWindow"
        Title="SmartProcure DataExtractor Workbench" Height="800" Width="1024" MinHeight="800" MinWidth="1024" Closed="Window_Closed">
...
                <telerik:RadDataServiceDataSource x:Name="dataServiceMdmHub" Height="100" Width="100" AutoLoad="True" PageSize="25" QueryName="ImportQueue">
                    <telerik:RadDataServiceDataSource.DataSourceContext>
                        <mdmhub:MdmHubEntitiesContext/>
                    </telerik:RadDataServiceDataSource.DataSourceContext>
                </telerik:RadDataServiceDataSource>

I tried many recommendations from other posts, but none have fixed the problem.  I can see in Object Browser that RadDataServiceDataSource has a DataSourceContext property, but VS is not able to find it to compile the project.

Thanks in advance

Hi,

RadDataServiceDataSource never had a property called DataSourceContext.

The property has always been and will always be DataServiceContext.
