Issue: ProvideMetadataAttribute

[Thomas]

With the assemblies after 27-11-2009 I get the following errors under visual studio 2008:

Could not load type 'Microsoft.Windows.Design.Metadata.ProvideMetadataAttribute' from assembly 'Microsoft.Windows.Design.Extensibility, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

I can build and run the project without problems, but I can't load the xaml designer.

Any ideas?

Hi Thomas,

Did you get the same error when you use the assemblies from our latest service pack release?

Hi,
I had the same problem with the latest release.
I have now changed to  vs 2010 and .net 4.0 beta 2. With this configuration I don't get the error message anymore.

[Steffen]

Hi,
I got the same problem with the new beta.
.NET 4.0/VS 2010 is currently no option for me.
The weird thing is that it just occures with some xaml-files and I have no clue what causes this.
When adding and deleting emty lines in the xaml sometimes the designer shows up for a short period of time.
Also the error-position points to a standard-wpf-listbox (line: <ListBox.ItemTemplate>) which had no problems before.
I'm using the RadGridView in datatemplates for standard-wpf-listboxes. Maybe it has to do something with this?
Any ideas?

Hello Steffen,

Did you get these issues if you try to use the latest internal build? Do you have a design folder, in the folder from which you are referencing telerik's assemblies?

Hi,

this morning the error "magically" disappeared (I think I did not change anything???).

Testing with the latest 2009.3 internal build would be quite time consuming because I have a lot of projects in
my solution which are referencing the dll's (and its working now).
I don't have any design-folder, I just add the dll's to the project-references.
If the error comes back, maybe I will recognize what causes this.


Best Regards
Steffen

I just updated to the Q1'10 release yesterday, and now I'm getting the same error.  I pasted the XAML below that it's complaining about.  We've got a column in a grid that puts a button in each row in that column in order to delete that row.

Updating to .NET 4.0 is not an option, and I *do* have a design folder with lots of Telerik.Windows.Controls.*.Design.dll files in it.

Thanks in advance for any suggestions on how we might resolve this problem.

I met same error.

I used VS2008 SP1 + .NET 3.5 on Telerik Q1 2010.

Error 1 '/Microsoft.Windows.Design.Developer;component/themes/GridAdorners.xaml' value cannot be assigned to property 'Source' of object 'System.Windows.ResourceDictionary'. Cannot create instance of 'GenericTheme' defined in assembly 'Microsoft.Windows.Design.Interaction, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Exception has been thrown by the target of an invocation.    Error at object 'ResourceDictionary_4'. C:\Users\GreenB\Documents\Visual Studio 2008\Projects\ModelBox\AWI.ModelBox\MainWindow.xaml 5 5 AWI.ModelBox

I try remove Telerik library from references then, error not raised. but I referenced them, error occurs.
What can I do?

[Steffen]

Hi,

the error "magically" reappeared in some files!
I need a solution for this.
The VS-XAML-designer could be a lot better but working absolutely "blind" is really annoying.

Hello all,

We are sorry for the late reply.

I suggest you login to your accounts and download the following zip:
http://www.telerik.com/downloads/productfiles/bacdb/VS2008_Design_Assemblies.zip

Using these design assemblies with Q1 2010 should fix the problem.

All the best,
Rosi

Hi, 
there weren't any design-dlls in my WPF-folder at all.
I used the zipped version because I uninstalled the "install"-version after the new Project-Update-Wizard repeatedly crashed my VS (fatal .NET 2.0 error => I already had this problem with a lot of VS-AddIns).
I still have 2009Q3 installed. Maybe VS took the wrong design-dlls?
So far nothing changed. I will deinstall 2009Q tomorrow and see what happens.

Best Regards
Steffen

I downloaded the new assemblies and extracted them to the design folder, then fired up my solution in VS.  I'm still seeing the same error.  I removed the RadGridView and telerik namespace from the XAML, and I also removed the project references to the Telerik assemblies.  I then added everything back in and rebuilt the project - still no change.  Any other suggestions?
Thanks,
Darcy

[Steffen]

Hi,
uninstalling the old version did not help.
Still the same issue.

Hello,

I don't know if it can help, but I have the error when I use "RadRibbonComboBox"

If i comment this using, all is ok, I can let the telerik dll and other telerik use in my code.

Just wanted to add that I am getting similar error. I think the problem is something very basic with Telerik's controls. I am getting the error in a project where I am not using any of the Telerik's controls, I have just included them as a reference. And when I remove the reference to the Telerik's DLLs the error goes away.

Here is the error message:
Could not load type 'Microsoft.Windows.Design.Metadata.ProvideMetadataAttribute' from assembly 'Microsoft.Windows.Design.Extensibility, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Line '1' Position '1425'.

And the interesting part is that, I didn't see the error the first time I add the control. After opening and closing the project, the problem appears. The problem is probably a mixture of Telerik and Microsoft. Telerik's controls are messing something with the Project settings, and then causing something outside the Telerik's controls to fail.

This problem is really annoying, and makes me wonder if I should stick with Telerik or look elsewhere.

[Hristo]

Hello Ujjwal Lahoti,

I am sorry to hear about your difficulties while using our controls. Please login to your accounts and download the following zip:
http://www.telerik.com/downloads/productfiles/bacdb/VS2008_Design_Assemblies.zip

Using these design assemblies with Q1 2010 should fix the problem. If this does not work try to upgrade with our latest internal build. If the problem still persist I would like to ask you to open a separate support ticket and attach there a sample project which demonstrates the problem to test it locally and provide you with further assistance.

Hristo

This doesn't fix the problem.

I haven't tried installing the Beta release, I will give it a try and see if they help.

However I tried the recommendations of others in this thread, to upgrade to Studio 2010 and .Net Framework 4.0. The problem does go away there. I am not sure if this is a viable solution for me or not.

There are other similar problems, look at the thread: http://www.telerik.com/community/forums/wpf/docking/could-not-create-an-instance-of-type-raddocking.aspx

One of the engineers in Telerik was able to reproduce the issue, however there was no solution, only a work around.

[Valentin.Stoychev]

Hello Ujjwal Lahoti,

There is a big launch event for the VS2010 this week. See more info here:
http://www.pcmag.com/article2/0,2817,2362464,00.asp

Please install the latest version and let us know if you still have problems.
