Creating RDLC Reports in Report Designer throws NullReferenceException

[System Administrator]

Hi,

I am following the instructions on http://help.syncfusion.com/ug/wpf/report%20designer/documents/creatingrdlcreportsi.htm to use objects as a data source.

Very little code is used but i have MainWindow.xaml.cs

    public partial class MainWindow : Window

    {

        public MainWindow()

        {

            InitializeComponent();

            Designer.DesignMode = DesignMode.RDLC;

            Designer.Assemblies = new List<Assembly>();

            Designer.Assemblies.Add(Assembly.GetExecutingAssembly());

        }

....

And MainWindow.Xaml

....

    <Grid>

        <Grid>

            <syncfusion:ReportDesigner x:Name="Designer" />

        </Grid>

    </Grid>

</Window>

And DataStore.cs which has the code pasted from the help topic.

When i run the builder and create a new data set as per the instructions it works fine until i try step 8 'Click Run to preview the report in the designer.'

When i click Run i get a System.NullReferenceException {"Object reference not set to an instance of an object."}

I can't seem to get it to work! If i do not have a datasource which references an object then it will not throw an exception. I have tried including every DLL in case its a reference problem.

Is there a working example of this somewhere?

Just to add a final comment (I can't seem to edit a post) I was looking at other posts by users (http://www.syncfusion.com/support/forums/wpf/reportdesigner/115630) and the source provided for one of the solutions has this exact same problem. I am using Visual Studio 2013 and have tried various framework versions.
