Question

I have a system with 2 different projects, one is called LINQ_Extensions and the other is ORM_Linq.

On ORM_Linq i have the LINQ diagram with the SQL tables “converted” in clases. One of the Class is called “Tipos_Pago”

In the other project i have another class (partial class) “Tipos_Pago”. I want to use the method OnValidate to validate the properties include in the class “Tipos_Pago”, so i create this partial class.

In the 2 projects i put the same NameSpace “ORM_Linq”(I changed the NameSpace of the project “LINQ_Extensions” to have the same of the project “ORM_Linq”)

After those chages, Visual Studio give me this error:

Error 1 No defining declaration found for implementing declaration of partial method ‘ORM_Linq.Tipos_Pago.OnValidate(System.Data.Linq.ChangeAction)’ C..\Tipos_Pago.cs 13 22 Extensiones_Linq

I don’t have any Idea of what happend, can someone help me?

Thanks, sorry for my poor english

This is the code in the partial class:

namespace ORM_Linq
{
    public partial class Tipos_Pago
    {

        partial void OnValidate(System.Data.Linq.ChangeAction action)
        {
         //Valid code
        }   
    }
}

You can’t implement a partial across 2 projects, since they have to be compiled together, the partial declarations must all be in the same project.

This same rule applies for methods and classes.
