Complete about Microsoft .NET Framework 2.0 ?

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.

New Window-Based Form Control

Overview:

Ø Debugger Edit and Continue Support

Ø I/O Enhancements

Ø .NET Framework Remoting

Ø Click Once Deployment

Ø Masked Text Box

Ø Sound Player Class

New Controls:

Ø Debugger Edit and Continue Support

l The .NET Framework 2.0 reintroduces the Edit and Continue feature

that enables a user who is

debugging an application in Visual Studio to

make changes to source code while executing in

Break mode.

Ø I/O Enhancements

l You can now use the classes in the

System.IO.Compression namespace to read

and write data with the GZIP compression

and decompression standard, described in

the IETF RFC 1951 and RFC 1952

specifications.

Ø .NET Framework Remoting

§ .NET Framework Remoting now supports IPv6

addresses and exchange of generics types.

Ø Click Once Deployment

You can deploy Windows client and commandline

applications. There are new Publish Project

commands on the Build and Project menus in

Visual Studio.

Ø Masked Text Box

Uses a masked definition to distinguish between a valid

and invalid user input.

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 control 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. For more information, see FlowLayoutPanel Control Overview and TableLayoutPanel Control Overview

l ListView control

The ListView control now supports three features provided by Windows XP and the

Windows Server 2003 family

l MenuStrip control

The MenuStrip is an enhanced menu system that is used with ToolStrip controls.

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 ToolStrip control

ToolStrip controls are toolbars that can host menus, controls, and user controls in your Windows Forms applications. The ToolStrip and its associated classes let you create toolbars and other user interface elements that can have a Windows XP, Office, Internet Explorer, or custom look of the interface. For more information, see ToolStrip Control Overview (Windows Forms).

l ToolStripContainer control

The ToolStripContainer provides built-in rafting and docking of ToolStrip, MenuStrip, and StatusStrip controls.

l WebBrowser control

The WebBrowser control lets you host Web pages in your Windows Forms applications

Conclusion:

From the discussion in this article, several evolving trends related to the new version of .Net 2.0 are observed. First, .NET 2.0 will be based on the simple controls and supports only some specify languages
