This code:

class IP: BaseClass
{
...
private string GetBusinessID(Int64 id)
{
            return Load<IP>(id).IPBusID;
}
...
}

is incorrectly made static.
("Load" is a static method defined in BaseClass.)

Resulting method:

class IP: BaseClass
{
...
private static string GetBusinessID(IP ip, Int64 id)
{
.IPBusID;
}
...
}


The "IP" parameter should not have been added in this case.

I can upload a .sln for this if you want.
