The rest of the application's code is replaced by short stubs -- their actual function code is transferred lazily in the background or, at the latest, on-demand on first execution. Since code download is interleaved with application execution, users can start interacting with the Web application much sooner, without waiting for the code that implements extra, unused features.

A nullable type can contain a value, or it can be undefined. The ?? operator defines the default value to be returned when a nullable type is assigned to a non-nullable type. If you try to assign a nullable value type to a non-nullable value type without using the ?? operator, you will generate a compile-time error. If you use a cast, and the nullable value type is currently undefined, an InvalidOperationException exception will be thrown.

I am working with SSRS 2005 since last 8 months and i came across many limitations which should not be there with SSRS . SSRS is still getting matured so please go through following list before choosing SSRS 2005 for reporting in your system.
Does not support dynamic width for columns:
SSRS doesn’t support dynamic width for columns , also the main problem I found is if you will disable one column based on condition then remaining columns width won’t get adjusted to use hidden columns space. And its very frustrating.
Doesn’t support HTML rendering !!!!!!!!!:
Yes, Its correct that SSRS 2005 doesn’t support HTML rendering of sent data. It is really surprising for me.
CanGrow property :
SSRS controls have cangrow property, if its true then controls will grow based on its contents width. But its can grow in vertical direction but not in horizontal.....
If this property is set to false then it will auto trim data based on controls width. and then if you want to show “...” to show there are some more data then you are in real trouble.
There are some more limitations are mentioned at here.
Hope all this problems are solved with SSRS 2008....:)

Choosing between ASP.NET Web Forms and MVC
ASP.NET MVC: America's Next Top Model View Controller Framework
Microsoft ASP.NET Model View Controller (MVC): Ninja on Fire Black Belt Tips

Basically MVC is a design pattern defined many years back and ASP.NET MVC Framework is the framework to implement MVC pattern.
As Per wordPress the defination of MVC Pattern is
“Model–View–Controller (MVC) is an architectural pattern used in software engineering. Successful use of the pattern isolates business logic fromuser interface considerations, resulting in an application where it is easier to modify either the visual appearance of the application or the underlying business rules without affecting the other. In MVC, the model represents the information (the data) of the application; the view corresponds to elements of the user interface such as text, checkbox items, and so forth; and the controller manages the communication of data and the business rules used to manipulate the data to and from the model.”
Now lets understand MVC Framework.
MVC is a framework methodology that divides an application’s implementation into three component roles: models, views, and controllers.
· “Models” in a MVC based application are the components of the application that are responsible for maintaining state. Often this state is persisted inside a database (for example: we might have a Product class that is used to represent order data from the Products table inside SQL).
· “Views” in a MVC based application are the components responsible for displaying the application’s user interface. Typically this UI is created off of the model data (for example: we might create an Product “Edit” view that surfaces textboxes, dropdowns and checkboxes based on the current state of a Product object).
· “Controllers” in a MVC based application are the components responsible for handling end user interaction, manipulating the model, and ultimately choosing a view to render to display UI. In a MVC application the view is only about displaying information - it is the controller that handles and responds to user input and interaction.
One of the benefits of using a MVC methodology is that it helps enforce a clean separation of concerns between the models, views and controllers within an application. Maintaining a clean separation of concerns makes the testing of applications much easier, since the contract between different application components are more clearly defined and articulated.
The MVC pattern can also help enable red/green test driven development (TDD) - where you implement automated unit tests, which define and verify the requirements of new code, first before you actually write the code itself.
Some benefits of MVC are :
Clear separation of concerns
Testability - support for Test-Driven Development
I will try to post more and more things about MVC.
