Assemblies Error

[ViinodVishwanatha]

Hello I am trying to use the User Login control available through the Silverlight Business Application Template. I have worked on an application for which I used a Standard ESRI silverlight template. I am getting an error at the following references in the xaml code. I copied the usercontrol folder and also actions folder from my ESRI silverlight template to the Business application template folder. and I added references to ESRI.ArcGIS.Client and also toolkit references to the project.
Error at the following line:

xmlns:userControls="clr-namespace:ESRI.ArcGIS.SilverlightMapApp"
    xmlns:actions="clr-namespace:ESRI.ArcGIS.SilverlightMapApp.Actions"

Shouldn't I be copying the folders directly?

Can some please help me fix this.
Thank you

First check that the user control you copied are still in the namespace 'ESRI.ArcGIS.SilverlightMapApp.Actions'.

If you changed the namespace in the .cs files, you have also to change it in the xaml.

Then, try to compile your application despite this designer error. This error can happen if you never compile your application but should not prevent to compile and run.
