Hi,

The error message translated to English would be something like:
The object of the "TelerikWpfApp16.TelerikWpfApp16.Application" can not be converted to type 'TelerikWpfApp16.Application ". Would you please check how have you defined your namespaces? What logic have you implemented on your MainWindow.btnOK_Click?

Regards,

MainWindow.btnOK_Click-Code:

MyConfigTable.ReadXml(My.Application.Info.DirectoryPath & "\" & "configuration.xml")

Before I used in this project the Telerik controls, this call has worked.

I have created a simple test project. Here is the XAML:

<Window x:Name="MyMainWindow" x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
Title="MainWindow" Height="350" Width="525">
<Grid>

</Grid>
</Window>

VB-Code:

Class MainWindow

Private Sub MyMainWindow_Loaded(sender As Object, e As RoutedEventArgs) Handles MyMainWindow.Loaded

Me.MyMainWindow.Title = My.Application.Info.ProductName

End Sub
End Class

‚ÄčAgain, I get the same error message.

Hello,

May I ask you to try isolating the issue in a demo project illustrating your exact setup and attach it in a new support ticket ? You can also take a look at this blog post for a reference on how to isolate an issue. 

That way I can check it locally and advise further.
