It is recommended to create our own base class for each business object type supported in CSLA.
My first attempt would be,
public abstract class MyBusinessBase<T> : BusinessBase<MyBusinessBase<T>>
{ ... }
public class Customer : MyBusinessBase<Customer>
{ ... }
In this case, BusinessBase takes MyBusinessBase<T> as my business object type and generates the Save method as follows, which the return type is not the target business object type.
public MyBusinessBase<T> BusinessBase<T>.Save() { ... }
I change the generic inheritance to:
public abstract class MyBusinessBase<T>
: BusinessBase<T> where T : MyBusinessBase<T>
{ ... }
In this version, the Save method from BusinessBase is generated as follows, which is correct in syntax.
public T BusinessBase<T>.Save() { ... }
Is this the correct way to use generic inheritance for CSLA classes?

William

There are already several threads that cover this. You might want to do a search for them.
Alternatively, take a look at RuleBusinessBase and RuleBusinessListBase in the CSLA Contrib project. They subclass BusinessBase and BusinessListBase.
