Problem Inserting Report Viewer into WPF Application using WindowsformsHost

Question

Hi

I am trying to create a popup from my WPF application which shows a report viewer hosted in a WindowsFormsHost however I am having problems with the following Xaml

<Page x:Class="FIS3.ReportViewer.ReportViewer"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:my="clr-namespace:System.Windows.Forms.Integration;assembly=WindowsFormsIntegration"
Title="MapViewer">
<Grid>
    <my:WindowsFormsHost>

    </my:WindowsFormsHost>
    <Label Name="exampleText" Content="this is the Report Viewer ..." />
</Grid>

I am getting a build error notifying me that "The type 'my:WindowsFormsHost' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built"

have I made an error in my XAML I have added WindowsFormsIntegration as a reference to my project.

Thanks for your help

According to the MSDN documentation, WindowsFormsHost is included in the default Xaml namespace ("http://schemas.microsoft.com/winfx/2006/xaml/presentation") - though you do need to reference WindowsFormsIntegration, as you have done. Have you tried referencing WindowsFormsHost with no namespace prefix?

<Page x:Class="FIS3.ReportViewer.ReportViewer"
 xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
 xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
 Title="MapViewer">
 <Grid>
   <WindowsFormsHost>

   <WindowsFormsHost>
  <Label Name="exampleText" Content="this is the Report Viewer ..." />
 </Grid>
