Rock, thanks for your reply. How about this post?

The solution provided by JonnyBee is similar to what I was looking for. I am currently in the middle of coding that solution in my app. Can you provide your insight on this solution?

Thanks

To create a base class you really need to make it MyBusinessBase<T> so the real business class is

public class MyRealClass : MyBusinessBase<MyRealClass>

The way CSLA uses generics in the base classes assumes T is always the type of the real business class.

I would like to implement Factory Pattern in CSLA. I can use an abstract base class or an interface for the abstraction. I have decided to use an abstract class, only because I have certain common functionality such as, saving to store, retrieving from store, and deletion of the record. Also, some properties that would apply to all implemented objects.

C# only allows for inheritance from one class, so I can either use BusinessBase or the abstract class. I would also like the concrete types to have their own set of business rules. How can this be done with CSLA?

If I do what I have listed below, will the rules in both the abstract class as well as the concrete class get fired?

Some code ...

Abstract class:

public class Form : BusinessBase<Form> {

private static PropertyInfo<string> FormNameProperty = RegisterProperty<string>(c => c.FormName);

public string FormName

{

get { return GetProperty(FormNameProperty); }

}

public abstract void LoadContent();

protected override void AddBusinessRules()

{

// business rules that are commmon for all implementations

}

Concrete implementation:

public class FormA : Form {

private static PropertyInfo<string> FirstNameProperty = RegisterProperty<string>(c => c.FirstName);

public string FirstName

{

get { return GetProperty(FirstNameProperty); }

}

public override void LoadContent(){

// some custom code

}

protected override void AddBusinessRules()

{

// business rules that only apply to this class

}

Factory:

public static class FormFactory{

public static Form GetForm(string formanmae) {

Type formType = GetFormType(formName);

if(formType == null)

return null;

var form = Activator.CreateInstance(formType) as ReferralForm;

return form;

}
