Problem using Silverlight Toolkit

11-06-2008 1:58 PM |

I have downloaded the latest versions of the silverlight toolkit/sdk. Un-installed all old beta and RC releases. I am now trying to use the Silverlight Toolkit which causes my build to fail. If anyone has any ideas on how to fix this it would be appreciated .

Problem : Cannot Compile when I add a a reference to the Microsoft.Windows.Controls.dll from the Silverlight toolkit.

Error:  Error    1    The "ValidateXaml" task failed unexpectedly.

Hi,
I've seen this one before. Can you try adding a reference to the 'System.Core' assembly of your application and rebuilding?

Thanks for the tip. I do have a reference to System.Core. I went ahead and removed then re-added the reference but I am still recieving the error upon compile. Any other ideas?

Hi,

Try to refer these two threads:

Hope them can help.

Looked at the solution in both links and I am still having the problem. I goto File->New Project->(Web)Silverlight Application

I add the web site to host the application,

Click on Reference in the Application Project and Browse to C:\Program Files\Silverlight ToolKit\bin and add a reference to Microsoft.Windows.Controls.dll 

When I try to compile i receive the error listed above.

System.Windows.dll just doesn't go missing. This *has* to be one of 2 things:

1. Your Visual studio installation is f***ed up :) It happens, beta software is called "beta" for a reason. Going over your "About" info everything looks in order, you have no Hotfixes, the correct SP1 version and a newer silverlight tools version than the one I'm using, so we're in the clear there. Allow me to suggest that if this is the problem, run a Visual Studio repair and Visual studio Silverlight tools repair and you should be fine.

2. You're not adding references correctly. You're either adding the "Microsoft.Windows.Controls.dll" reference to a .Net CLR project (like maybe trying to add MWC.dll to the asp.net project...?) or trying to add it through the wrong Tab (again, trying to mix between CLRs).
If this is the issue, please specify step by step how you start a new project and add a reference until you see this error.
Allow me to suggest that you install blend and try using the Silverlight Toolkit dlls from there and than opening the project in Visual studio. That would confirm you are adding the references incorrectly in Visaul studio.
