Create the localizable resource
After you reference the required assemblies, you create the localizable resources. Every module can have a list of localizable resources. In Sitefinity CMS, you wrap the resources in a class that inherits the Resource base class.
To create the resources class for the custom personalization:
    - In Visual Studio, open the context menu of your project (for example the DayOfWeekPersonalization project for this tutorial) and click Add » New Item..
 
    - In the left pane, select Visual C# » Class
     
    - Name the class file CustomPersonalizationResources.cs and click Add.
 
    - Make the CustomPersonalizationResources class inherit the Resource class. 
 
    - Mark the class with the ObjectInfo attribute.
 
    - Define the constructor of the class.
 
    - Add the resource entries to the class.
    You create localizable resource entries, which will be used as field and title values in a later step of this tutorial. 
Use the following sample code:
