Asp.NET 2.0 Job Interview Questions (Part 1)
What are the new Data Controls in Asp.net 2.0?
Data access in ASP.NET 2.0 can be accomplished completely declaratively (no
code) using the new data-bound and data source controls. There are new data
source controls to represent different data backends such as SQL database,
business objects, and XML, and there are new data-bound controls for rendering
common UI for data, such as gridview, detailsview, and formview.
What are the new Navigation Controls in Asp.net 2.0?
The navigation controls provide common UI for navigating between pages in your
site, such as treeview, menu, and sitemappath. These controls use the site
navigation service in ASP.NET 2.0 to retrieve the custom structure you have
defined for your site.
What are the new Login Controlsin Asp.net 2.0?
The new login controls provide the building blocks to add authentication and
authorization-based UI to your site, such as login forms, create user forms,
password retrieval, and custom UI for logged in users or roles. These controls
use the built-in membership and role services in ASP.NET 2.0 to interact with
the user and role information defined for your site.
What are the new Web Part Controls in Asp.net 2.0 ?
Web parts are an exciting new family of controls that enable you to add rich,
personalized content and layout to your site, as well as the ability to edit
that content and layout directly from your application pages. These controls
rely on the personalization services in ASP.NET 2.0 to provide a unique
experience for each user in your application.
What are Master Pages?
This feature provides the ability to define common structure and interface
elements for your site, such as a page header, footer, or navigation bar, in a
common location called a "master page", to be shared by many pages in your
site. In one simple place you can control the look, feel, and much of
functionality for an entire Web site. This improves the maintainability of your
site and avoids unnecessary duplication of code for shared site structure or
What are Themes and Skins in 2.0, explain usgae scenario?
The themes and skins features in ASP.NET 2.0 allow for easy customization of
your site's look-and-feel. You can define style information in a common
location called a "theme", and apply that style information globally to pages
or controls in your site. Like Master Pages, this improves the maintainability
of your site and avoid unnecessary duplication of code for shared styles.
What is a profile object, why is it used?
Using the new personalization services in ASP.NET 2.0 you can easily create
customized experiences within Web applications. The Profile object enables
developers to easily build strongly-typed, sticky data stores for user accounts
and build highly customized, relationship based experiences. At the same time,
a developer can leverage Web Parts and the personalization service to enable
Web site visitors to completely control the layout and behavior of the site,
with the knowledge that the site is completely customized for them.
Personalizaton scenarios are now easier to build than ever before and require
significantly less code and effort to implement.
What is Configuration API?
ASP.NET 2.0 contains new configuration management APIs, enabling users to
programmatically build programs or scripts that create, read, and update
Web.config and machine.config configuration files.
What is MMC Admin Tool?
ASP.NET 2.0 provides a new comprehensive admin tool that plugs into the
existing IIS Administration MMC, enabling an administrator to graphically read
or change common settings within our XML configuration files.
Explain the use of Pre-compilation Tool?
ASP.NET 2.0 delivers a new application deployment utility that enables both
developers and administrators to precompile a dynamic ASP.NET application prior
to deployment. This precompilation automatically identifies any compilation
issues anywhere within the site, as well as enables ASP.NET applications to be
deployed without any source being stored on the server (one can optionally
remove the content of .aspx files as part of the compile phase), further
protecting your intellectual property.
How is application management and maintenance improved in Asp.net 2.0?
ASP.NET 2.0 also provides new health-monitoring support to enable
administrators to be automatically notified when an application on a server
starts to experience problems. New tracing features will enable administrators
to capture run-time and request data from a production server to better
diagnose issues. ASP.NET 2.0 is delivering features that will enable developers
and administrators to simplify the day-to-day management and maintenance of
their Web applications.
What are Provider-driven Application Services? explain in detail?
ASP.NET 2.0 now includes built-in support for membership (user name/password
credential storage) and role management services out of the box. The new
personalization service enables quick storage/retrieval of user settings and
preferences, facilitating rich customization with minimal code. The new site
navigation system enables developers to quickly build link structures
consistently across a site. As all of these services are provider-driven, they
can be easily swapped out and replaced with your own custom implementation.
With this extensibility option, you have complete control over the data store
and schema that drives these rich application services.
Explain Server Control Extensibility with reference to Asp.net 2.0 ?
ASP.NET 2.0 includes improved support for control extensibility, such as more
base classes that encapsulate common behaviors, improved designer support, more
APIs for interacting with client-side script, metadata-driven support for new
features like themes and accessibility verification, better state management,
What are the Data Source Controls?
Data access in ASP.NET 2.0 is now performed declaratively using data source
controls on a page. In this model, support for new data backend storage
providers can be easily added by implementing custom data source controls.
Additionally, the SqlDataSource control that ships in the box has built-in
support for any ADO.NET managed provider that implements the new provider
factory model in ADO.NET.
What are Compilation Build Providers?
Dynamic compilation in ASP.NET 2.0 is now handled by extensible compilation
build providers, which associate a particular file extension with a handler
that knows how to compile that extension dynamically at runtime. For example,
.resx files can be dynamically compiled to resources, .wsdl files to web
service proxies, and .xsd files to typed DataSet objects. In addition to the
built-in support, it is easy to add support for additional extensions by
implementing a custom build provider and registering it in Web.config.
What is Expression Builders, why would you use it?
ASP.NET 2.0 introduces a declarative new syntax for referencing code to
substitute values into the page, called Expression Builders. ASP.NET 2.0
includes expression builders for referencing string resources for localization,
connection strings, application settings, and profile values. You can also
write your own expression builders to create your own custom syntax to
substitute values in a page rendering.
Is ASP.NET 64-Bit enabled? how?
ASP.NET 2.0 is now 64-bit enabled, meaning it can take advantage of the full
memory address space of new 64-bit processors and servers. Developers can
simply copy existing 32-bit ASP.NET applications onto a 64-bit ASP.NET 2.0
server and have them automatically be JIT compiled and executed as native
64-bit applications (no source code changes or manual re-compile are required).
Explain how Caching in Asp.net 2.0 is different from Caching in Asp.net
ASP.NET 2.0 also now includes automatic database server cache invalidation.
This powerful and easy-to-use feature allows developers to aggressively output
cache database-driven page and partial page content within a site and have
ASP.NET automatically invalidate these cache entries and refresh the content
whenever the back-end database changes. Developers can now safely cache
time-critical content for long periods without worrying about serving visitors
