Introduction:
The new version of .NET Framework which
is .NET Framework 2.0
introduced with lot of new features which
is now more affective, useful
then the old version of .NET which is .NET
Framework 1.1.
Here we define the new features which
are introduced in .NET 2.0…
We hope it will useful and complete…
.Net
Framework is an integrated and managed environment for the
development and execution of your code.
.Net
allocates memory for the storage of data and instructions, grants or
denies the appropriate permissions to
your application, initiates and
manages application execution and manages the
re-allocation of memory
from
resource that are no longer needed.

Overview:
Ø .NET Framework
§
.Net provides
development tools, run-time environment, server infrastructure and intelligent
software which enable you to build application for various platform and
devices.
§
“The .NET
Framework is an integral Windows component that supports developing, deploying
and running the applications and XML Web services.”
Changes in 2.0 in comparison with 1.1:
Here are the
changes which are performed in the new version of .NET Framework 2.0:
l Numerous API changes.
l A new hosting API for native applications wishing to
host an instance of the .NET runtime. The new API gives a fine grain control on
the behavior of the runtime with regards to multithreading, memory allocation,
assembly loading It was initially developed to efficiently host the runtime in Microsoft SQL Server,
which implements its own scheduler and memory manager.
l Full 64-bit support for both the x64 and the IA64
hardware platforms.
l Language support for generics built
directly into the .NET CLR.
l Many additional and improved ASP.NET web controls.
l New data controls with declarative data binding.
l New personalization features for ASP.NET, such as
support for themes, skins and webparts.
l .NET Micro Framework
- a version of the .NET Framework related to the Smart
Personal Objects Technology initiative.
l Partial classes
l Anonymous methods
l Generics
l Data Tables
Net Framework Remoting:
Ø .Net Framework
Remoting:
§
.NET Remoting
is a Microsoft application
programming interface (API) for interprocess communication
released in 2002 with the 1.0 version of .NET Framework. It is
one in a series of Microsoft technologies that began in 1990 with the first
version of Object
Linking and Embedding (OLE) for 16-bit Windows.
§
.Net remoting
is used to enable communication between different applications .
§
Computers may
be part of network, .NET Remoting is an enabler for application communication.
.Net Remoting Architecture:

Features of .NET Framework Remoting:
Ø Multiple transfer mechanisms – HTTP/TCP
If there is no web server running – put
traffic on port 80
Ø Multiple encodings – SOAP/ Binary
(Your own-serialization)
Ø .NET Remoting is more flexible (more activation and
deployment options)
Ø .NET Remoting is customizable (you can add logging or
other features)
Ø .Net Remoting enables you to work with stateful
objects
Ø Interface description does not have to be manually
coded in any way, as metadata can be extracted from running servers, or from
any .Net assembly
Ø One of the major benefits is that it’s centralized
around well-known and well-defined standards like HTTP and is directly tied to
the .Net Framework
Globalization:
Ø What is
Globalization?
§
Globalization
(globalization) in its literal sense is the process of transformation of local
or regional phenomena into global ones. It can be described as a process by
which the people of the world are unified into a single society and function
together.
§
It is an
process in which it run across all platforms and all sites with minimum or no
modification to the application.
§
It also makes
locally prevailing information on culture. Like location information and
language used in particular location.
Features of Globalization:
Ø
Feature introduced in .Net 2.0:
§
CultureAndRegionInfoBuilder class
§
Support for custom cultures enables you to define and deploy
culture-related information as needed. This feature is useful for creating
minor customizations of existing culture definitions, and creating culture
definitions that do not yet exist in the .NET Framework. For more information,
see the CultureAndRegionInfoBuilder
class.
§
System.Text namespace
§
Encoding and decoding
operations map a Unicode character to or from a stream of bytes that can be
transferred to a physical medium such as a disk or a communication line. If a
mapping operation cannot be completed, you can compensate by using the new
encoding and decoding fallback feature supported by several classes in the System.Text
namespace.
§
UTF8Encoding class
§
Members in the UTF8Encoding
class, which implements UTF-8 encoding, are now several times faster than in
previous releases. UTF-8 is the most common encoding used to transform Unicode
characters into bytes on computers.
§
Support Latest Normalization Standard
§
The .NET Framework now
supports the latest normalization standard defined by the Unicode Consortium.
The normalization process converts character representations of text to a
standard form so the representations can be compared for equivalence.
§
CultureInfo class
§
The GetCultureInfo
method overload provides a cached version of a read-only CultureInfo
object. Use the cached version when creating a new CultureInfo
object to improve system performance and reduce memory usage.
Manifest – Based Activation:
l
Overview
Manifest is an XML based, database driven
Content
Management System (CMS) for satisfying
corporate
communications needs, including Internet and
Intranet.
Traditional web development
packages focus on creating
a Website one page at a time, often immersing
the author
in complex HTML code
Manifest – Based Activation:
l
ClickOnce
Manifest-based activation is essential
for supporting ClickOnce
applications. Traditionally, applications
are activated through
a reference to an assembly that contains
the
application's entry point.
l Web Application
The
manifest-based activation model uses an application manifest for activation
rather than an assembly. A manifest fully describes the application, its
dependencies, security requirements, and so forth. The manifest model has
several advantages over the assembly-based activation model, especially for Web
applications.
Manifest – Based Activation:
l
APIs
Manifest-based
activation is provided by a set of APIs that allow managed hosts to activate
applications and add-ins described by a manifest. These APIs contain a mixture
of both new classes and extensions to existing classes.
l This activation model also invokes an entity called a
Trust Manager that performs the following tasks:
l
Determines
whether an application is allowed to be activated. This decision can be made by
prompting the user, querying policy, or by any other means deemed appropriate for
a given Trust Manager.
l
Sets up the
security context to run an application in. Most commonly, this step involves
setting up a code access security (CAS) policy tree on the application domain
in which the application will run.
New Window-Based Form Control:
.Net
Framework 1.0 was released on January 16,2002
which was its first version. After
that version 1.1 was
released on April 24,2003 which was released
together
With Windows 2003 Server.
Latest version is .net framework 2.0 which
was
released on November 7, 2005 with Visual
Studio 2005
and SQL Server 2005.

Ø Sound Player Class
The SoundPlayer class enables you to play
sounds file in
.wav format and enables you to load or play
sounds
asynchronously.
Ø Table Layout Panel
The TableTayOut panel controls arranges its
contents in a grid.
Because the layout is performed both at
design time and run time, it
can change dynamically as the application
environment changes.
Some Other Controls in .NET 2.0:
l
ContextMenuStrip control
The ContextMenuStrip
is an enhanced shortcut menu used with ToolStrip
controls
l
DataGridView control
The DataGridView
control provides a powerful and flexible way to display data in a
tabular format. It can be
used to show read-only views of a small amount of data, or
it can be scaled to show
editable views of very large sets of data. The data can reside
in an external data source
or be added directly to the control. For more information,
see DataGridView
Control Overview (Windows Forms).
l
Layout panels
The FlowLayoutPanel
control arranges its contents in a horizontal or vertical flow
direction.
The TableLayoutPanel

l
SplitContainer control
The Windows
Forms SplitContainer
control can be thought of as a composite; it is two panels separated by a
movable bar. When the mouse pointer is over the bar, the cursor changes to show
that the bar is movable. Use it to create complex, resizable user interfaces
that are most effective for displaying and browsing information. For more
information, see SplitContainer
Control (Windows Forms).
l
StatusStrip control
The StatusStrip
is an enhanced status bar used with ToolStrip
controls.
l
