I\'m modifying demo application from this article: http://msdn.microsoft.com/en-us/magazine/dd419663.aspx
I need to update all files to use my namespace, for example
You can use ReSharper for namespace refactoring. It will give 30 days free trial. It will change namespace as per folder structure.
Steps:
Right click on the project/folder/files you want to refactor.
If you have installed ReSharper then you will get an option Refactor->Adjust Namespaces.... So click on this.
It will automatically change the name spaces of all the selected files.
