ASP.NET 3.5 Inteview Questions

What’s the difference between Response.Write() andResponse.Output.Write()?


Response.Output.Write() allows you to write formatted output.

What methods are fired during the page load?

Init() - when the page is instantiated

Load() - when the page is loaded into server memory

PreRender() - the brief moment before the page is displayed to the user as HTML

Unload() - when page finishes loading.


When during the page processing cycle is ViewState available?

After the Init() and before the Page_Load(), or OnLoad() for a control.


What namespace does the Web page belong in the .NET Framework class hierarchy?

System.Web.UI.Page


Where do you store the information about the user’s locale?

CodeBehind is relevant to Visual Studio.NET only.

What’s the difference between Codebehind="MyCode.aspx.cs" andSrc="MyCode.aspx.cs"?

CodeBehind is relevant to Visual Studio.NET only.

What is the Global.asax used for?

The Global.asax (including the Global.asax.cs file) is used to implement application and session level events.

What are the Application_Start and Session_Start subroutines used for?

This is where you can set the specific variables for the Application and Session objects.


Whats an assembly?

Assemblies are the building blocks of the .NET framework;

Whats MSIL, and why should my developers need an appreciation of it if at all?

MSIL is the Microsoft Intermediate Language. All .NET compatible languages will get converted to MSIL. MSIL also allows the .NET Framework to JIT compile the assembly on the installed computer.



Which method do you invoke on the DataAdapter control to load your generated dataset with data?

The Fill() method.


Can you edit data in the Repeater control?

No, it just reads the information from its data source.



Which template must you provide, in order to display data in a Repeater control?

ItemTemplate.
Name two properties common in every validation control?

ControlToValidate property and Text property.
What base class do all Web Forms inherit from?

The Page class.

What is the difference between Server.Transfer and Response.Redirect? Why would I choose one over the other?

Server.Transfer transfers page processing from one page directly to the next page without making a round-trip back to the client's browser. This provides a faster response with a little less overhead on the server. Server.Transfer does not update the clients url history list or current url. Response.Redirect is used to redirect the user's browser to another page or site. This performas a trip back to the client where the client's browser is redirected to the new page. The user's browser history list is updated to reflect the new address

What is ViewState?

ViewState allows the state of objects (serializable) to be stored in a hidden field on the page. ViewState is transported to the client and back to the server, and is not stored on the server or any other external source. ViewState is used the retain the state of server-side objects between postabacks.

What is the lifespan for items stored in ViewState?

Item stored in ViewState exist for the life of the current page. This includes postbacks (to the same page).

What does the "EnableViewState" property do? Why would I want it on or off?

It allows the page to save the users input on a form across postbacks. It saves the server-side values for a given control into ViewState, which is stored as a hidden value on the page before sending the page to the clients browser. When the page is posted back to the server the server control is recreated with the state stored in viewstate.

What are the different types of Session state management options available with ASP.NET?

ASP.NET provides In-Process and Out-of-Process state management. In-Process stores the session in memory on the web server. This requires the a "sticky-server" (or no load-balancing) so that the user is always reconnected to the same web server. Out-of-Process Session state management stores data in an external data source. The external data source may be either a SQL Server or a State Server service. Out-of-Process state management requires that all objects stored in session are serializable.

Windows Communication Foundation [WCF] - Interview questions

What is Windows Communication Foundation, WCF?


WCF helps in building applications to communicate with each other. It is a framework that helps in managing distributed computing.


What are the components of WCF?


Components of WCF Contracts and descriptions: - Describes different features of messaging. The features are described by Data contract, message contract, service contract and policy and binding.


What is the difference between WCF and Web services?


WCF has a variety of distributed programming infrastructures. WCF offers more flexibility and portability.


What is duplex contracts in WCF?


WCF allows duplex messaging pattern. Services can communicate with client through a callback. Duplex messaging in WCF.


What are different binding supported by WCF?


Different bindings


Built- in bindings and custom bindings. When the built in or system provided bindings are not suited for the requirement.


How do we use MSMQ binding in WCF?


Message queue allows applications running at different times to send and read messages from queues. WCF uses transactional queue to capture messages, delivered and stored.


Explain volatile queues and Dead letter queues.


WCF also uses non transactional queues for storing messages. Such queues are volatile in nature. They are stored in memory and not used in transactions. On shutting down the machine, the queue is lost.


What are the various ways of hosting a WCF service?


Ways of hosting WCF Service: Self hosting: - The service code is embedded within the application code. An end point for the service is defined and an instance of SeriveHost is created.


Explain transactions in WCF.


Transactions in WCF allow several components to concurrently participate in an operation.


What are the various programming approaches for WCF?


Programming approaches for WCF: Imperative: - Different programming languages can be sued for implementing service logic.


What are the advantages of hosting WCF services in IIS?


Advantages of hosting WCF services in IIS : Provides process activation and recycling ability thereby increasing reliability


What are different isolation levels provided in WCF?


The different isolation levels: READ UNCOMMITTED: - An uncommitted transaction can be read. This transaction can be rolled back later .
