About 'Microsoft.Windows.Design.Services.ValueTranslationService' to be present, but it could not be located

[lin]

When I update my project's radcontrol with 2010 Q1. In blend design mode, the page with RadWindow, blend throw exception:
This feature requires service 'about 'Microsoft.Windows.Design.Services.ValueTranslationService' to be present, but it could not be located'

How to resolve this problem?

I had this warning (it was not preventing my application to start) while adding a Telerik gridview to a WPF windows using Visual Stutio 19. I am only using trial for the moment to create a demo and compare it with Infragistics, (like Infragistics could be at same level for WPF.....) and I am mentioning that because my problem and obviously my solution could be affected by 1.- Trial version 2.- First time use Telerik 3.- I use also Infragistic references all over the views.

I solve it (it took like 2 min and a couple of builds to disappear) at least for a couple of days now by adding designInstance to the usercontrol (.Xaml) we use as template. Error was not in all the templates, it is a bit random even if I remove the designInstance the error does not comeback immediately . Example Below:

xmlns:vm="clr-namespace:<yourVmsNamespace>"

mc:Ignorable="d"

d:DataContext="{d:DesignInstance vm:<yourVmClass>, IsDesignTimeCreatable = False}"

I will update if the error comeback!

Hello lin,

I have not seen this error before, but after some investigation I managed to find some info. Most probably this is caused because you are missing Microsoft.Windows.Design.Extensibility.dll, it should be situated in
C:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\IDE\PublicAssemblies, if you don't have it there maybe you have something corrupted with .NET Framework installation. Another thing I can advise you is to install Blend Expression. As far as i know Blend installation should install Microsoft.Windows.Design.Extensibility.dll . If installing Blend itself doesn't help try to copy this dll to the path mentioned above.

Hope this helps.

All the best,

I have the same problem after upgrading to 2010 Q1.
But I have the dll in the proper directory in VS.
How did you fix this problem?

Thanks,

Michael

Hi Michael,

There is another problem in the Q1 design assemblies - you could download the fixed binaries from your account:
http://www.telerik.com/account/downloads/product-versions/single-version.aspx?pmvid=2174&pid=0

By the way, copying assemblies to the PublicAssemblies folder is no longer required.

This is really bad advice ... the Microsoft.Windows.Design.Extensibility.dll from that directory is NOT a Silverlight assembly, it's a .NET framework assembly.
