Introduction:Overview:
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.
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-bitWindows.
§ .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:CultureAndRegionInfoBuilder class.
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
§ 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
