You an use resource string instead. An overload of Required field attribute allows you to pass in resource class and respective fieldName.

[Required(ErrorMessageResourceType = typeof(Resource1), ErrorMessageResourceName = "requiredField")]

To add a resource file if it's not already exists in your project simply right click on your project. Add new item and select resource file. After adding it in the project you can double click to open it and enter your string for validation message:

Vendettamit's answer is correct, but if you don't wish to use resources for some reason, it will work to mark your string const instead of readonly.

public const string Required = "Required Filed";
