  How does this guy get the time to read and try all this stuff.
  Excellent and cool list.
  
  
  
  1. New Architectural Guidance coming from patterns and practice.
  
  
  2. The general direction of xUnit
  My Comment: I will stick with MSTest right now.
  
  3. AAA syntax and mocking styles in Rhino Mocks and Moq.
  My Comment: Loved it. I liked more Moq for its simplicity but keep Rhino Mocks as back up.
  
  4. Nate Kohari's approach to convention based setter injection in Ninject
  http://dojo.ninject.org/Conventions-Based%20Binding.ashx
  My Comment: Interesting. I am okay with Configuration or Custom Attributes approach for AOP. Convention approach sounds little backward but can be handy in certain situations.
  
  5. Autofac’s extensibility Model
  http://code.google.com/p/autofac/wiki/GettingStarted
  My Comment: Another DI framework
  
  6. StructureMap
  
  
  7. New Language features in .NET 3.5
  1) Lambda expression
  2) Var
  3) Object Initializer
  4) Collection Initializer
  5) Extension Methods
  6) Anonymous Types
  7) Auto Implemented Methods
  8) Partial Methods
  
  8. Expression Tree
  
  9. JQuery

  My comment:- I am going to buy a book to master this javascript framework.
  
  10. MassTransit

  My Comment:- It sounds more like command pattern. There may be more. I need to investigate more into this.
  
  
  11. Linq to NHibernate and Linq in general of course
  My Comment: Since Generics in .NET2.0, LINQ is best thing that has happened in .NET3.5
  
  12. More powerful Auto Mapping and convention support for Fluent Nhibernate
  http://code.google.com/p/fluent-nhibernate/
  My Comment:- I will stick to LINQ for SQL time being. I hated the XML configuration for Nhibernate as it was error prone. Active record was a compromise.
  
  
  13. Bellware's SpecUnit assertion extensions
  My Comment:- Makes unit test more readable and maintainable.
  
  14. Fluent Fixture

  Resharper Rocks
  
  19. AutoMocker and Interaction Context base Classes
  
  20. Dino Esposito's latest book on .Net architecture
  My Comment:- I did a quick reading at book store. My rating 5 out of 5.
  
  21. Ben Scheirman's new fluent API for testing routes in MVC
  
  22. Rake Build Tool

CLSA .Net 3.6 Overiew

http://www.lhotka.net/weblog/OverviewOfCSLANET36ForWindowsAndSilverlight.aspx


I have added the Expert 2008 Busines Objects to my 'to read' list.
I also share the Rocky's view that UI future belongs to WPF/Silverlight/XAML .


Subsystems of CSLA.NET 3.6

1. 90% of the code will be shared between .net and silverlight applications,with less than 10% code being different.
My Comment - Amen

2. Databinding
My Comment -Databinding reduces the plumbing between UI and business objects. That is something our frameworks should exploit

3. Object Status Tracking(new, changed , marked for deletion)
My Comment - Cool


4. Standardization of business and validation rule processing

5. Integration with, and simplification of , .NET authentication model.

6. Undo capabilities
Not too exciting feature for Web Based applicaions.

7.Enhanced support for LINQ queries against your business model.
My Comment--
LINQ is for major enhancement in .NET 3.5 platform since Generics in .NET 2.0
LINQ is something definately that one should exploit.

8. Aysnchronous data access and Asynchronous Validation Rules
My Comment--
I can understand that one can run the queries and expect to notified by the system.Aysnchronous Validation. Beats me.


These subsystems are exposed through a set of base classes from which you inherit to create your business objects. These base classes enable a set of object stereotypes:
1. Editable Root
2. Editable Child
3. Dynamic list -- Not for asp.net
4. Read-only root
5. Read-only Child
6. Name/Value List
7. Command

My Comment-
Only Command Pattern sounds interesting other bases classes sounds more like noise in the framework.
It is interesting how one can abstract Command Pattern in the framework.


Mobile Objects-
My Comment - With Remoting out of favor, Mobile objects sound more like a philosphical approach than tactical solution.


CSLADataSource & DataMapper
My Comment -- Having burnt my fingers with Object Data Source, having Custom Object Data Source is way to go. With Mobile Objects out of favor, you need DataMapper to convert proxy objects/Data Objects into real Business Objects.


WindowFlowManger:-
Simplifies launching,suspending and resuming a workflow instance.


CSLA.Net for SilverLight

Moq,RhinoMock and Lambda(AAA) expressions

Last time I played with RhinoMock , I was in state of shock and awe. I was awed because it improved my design. It requrired that the code under test should to be isolated from rest of application. That was done using Interfaces . Contract based programming is always best way of programming. I could test behavioral aspect of my code.It would have been little difficult using xUnit framework. It was almost creating a simulation flight envrionment and enjoying the pleasure of real flights.

I was also shocked by the fact that my behavioral tesing Line of codes were many times more than code under test.

I was left in no doubt that Mocking is very powerful and advance technique of TDD. Also at the same time, It will make selling TDD difficult to people new to programming.

Hopefully Lambda expression may help in that direction.

Design and Testability

Good Question.

Can you write effective unit tests without knowlegde of designing ?
I think that Jeremy is right in saying no.
OOP is all about design.
Concepts like Object, Collaboration and Messaging or Inheritance,Polymorphism and Encapsulation are all about design.

If a person does not understand OOP,Domain Driven Design, he can hardly write effective unit tests.

In OOP , one has to take 100 design decisions(which code goes to which class or layer) per day.

TDD is advance concept to master. One has to learn OOP and Design Patterns before that.
