   What's New in Visual Studio .NET 2003

Please help in keeping this site Free

1.)   What's New in the .NET Framework Version 1.1

1.) ASP.NET Mobile Controls - (formerly the Microsoft Mobile Internet Toolkit)

ASP.NET Mobile Controls (formerly the Microsoft Mobile Internet Toolkit) extends the .NET Framework and Visual Studio .NET by providing support for mobile (wireless) devices such as cell phones and personal data assistants (PDAs). The .NET Framework version 1.1 release incorporates the mobile controls into the .NET Framework and Visual Studio .NET distributions.
Because mobile controls are now a part of the .NET Framework, the terminology has changed to match the conventions used in .NET documentation, and the mobile controls documentation has merged into the larger .NET Framework documentation set. The name Mobile Internet Toolkit is replaced by ASP.NET Mobile Controls.
ASP.NET Mobile Controls extend ASP.NET server controls such that they adapt to the mobile device on which the Web application is rendering. Through browser detection, the mobile controls conform to the capabilities of individual devices ranging from full-featured PDA browsers to small, 5-line × 20-character cell phone displays. This adaptive rendering feature handles many of the tedious device-specific rendering decisions and frees you to focus on your Web application logic.

2.) ADO.NET - Changes in ADO.NET

The .NET Framework Data Provider for ODBC, which previously was available as a Web download only, now ships with the .NET Framework under the namespace System.Data.Odbc.
The .NET Framework Data Provider for Oracle now ships with the .NET Framework under the namespace System.Data.OracleClient. Developers using the .NET Framework version 1.0 can download the .NET Framework Data Provider for Oracle from http://msdn.microsoft.com/downloads.
In addition, ADO.NET now includes the following features:
The DataReader object now exposes a HasRows property to    determine if rows were returned without having to call Read. For more    information, see Retrieving Data Using the DataReader.
The Connection object now has an EnlistDistributedTransaction    method to enable manual enlistment in distributed transactions. For    more information, see Performing Transactions.

3.) Side-by-Side Execution :

The .NET Framework version 1.1 supports side-by-side execution. Side-by-side execution is the ability to store and execute multiple versions of an application or component on the same computer. This means that you can have multiple versions of the runtime, and multiple versions of applications and components that use a version of the runtime, on the same computer at the same time. In addition, subsequent installations of other versions of the .NET Framework or of a component will not affect the applications already installed. For more information, see Side-by-Side Execution.
Side-by-side execution does not imply that a managed application is compatible with other versions of the runtime or of a component. Rather, it means that a managed application can choose the runtime and the components it executes with, and that multiple versions of the runtime, applications, and components can coexist on the same computer. It is up to you to decide which versions of the runtime and which components a particular application will use.

4.) Changes in .NET Framework Security :

In version 1.0 and 1.1, applications that receive less than full trust from the runtime code access security system cannot call shared managed libraries unless the library writer specifically allows them to through the use of the AllowPartiallyTrustedCallersAttribute attribute. If you plan on using libraries from partially trusted code, you need to be aware that some libraries will not be available to your code. In version 1.1, System.Web.dll, System.Web.Mobile.dll, and System.Web.RegularExpressions.dll are included in the list of assemblies that have the AllowPartiallyTrustedCallersAttribute and can be called from partially trusted code. For more information, see Using Libraries from Partially Trusted Code.
Default security policy has been changed so that applications executing from the Internet zone and assigned to the Internet Zone code group now receive permissions associated with the Internet permission set. As a result, applications from the Internet now receive sufficient permission to execute. In the .NET Framework 1.0 Service Pack 1 and Service Pack 2, such applications received the permissions associated with the Nothing permission set and could not execute.

5.) ASP.NET Security :

ASP.NET now supports partial trust in Web-based applications, offering greater security for multiple applications that are hosted on a single Web server. Although the operating system account under which an application runs imposes security restrictions on the application, the code access security system of the common language runtime can enforce additional restrictions on selected application resources based on policy that you specify. You can use this feature in a shared server environment to isolate separate applications and with standalone servers where you want applications to run with the minimum necessary privileges.
ASP.NET provides a <trust> configuration directive that enables you to configure code access security levels for your applications. If your partially trusted ASP.NET applications call shared managed libraries, those libraries must contain an AllowPartiallyTrustedCallersAttribute attribute that allows calls from partially trusted code. For more information, see Using Libraries from Partially Trusted Code.

6.) IPv6 Support in the .NET Framework :

The .NET Framework version 1.1 supports the emerging update to the Internet Protocol, commonly referred to as IP version 6, or simply IPv6. This protocol is designed to significantly increase the address space used to identify communication endpoints in the Internet to accommodate its ongoing growth. IPv6 is supported in the System.Net namespace, ASP.NET, and XML Web services.

2.)   What's New in Visual Studio .NET 2003

1.) Solutions Explorer - Track Active Item :

A new option in visual studio 2003, Track Active Item in Solution Explorer, has been added to the Projects and Solutions, Environment, Options Dialog Box. When this option is selected, Solution Explorer automatically opens the folder for the active item, scrolls to its node, and selects its name. The selected item changes as you work with different files within a project or solution, or different components within an Integrated Development Environment (IDE) designer. When this option is cleared, the selection in Solution Explorer does not change automatically. This option is enabled by default, but it is cleared when you choose the "Visual C++ Developer" or "Visual C# Developer" profile on the My Profile tab of the Visual Studio Start Page.

2.) New icons :

Checked Out Exclusive - Item is checked out from a source control    database to one developer only. Other developers cannot access this    file.
Checked Out Shared - Item is checked out from a source control    database for shared use by a development team. Different versions of    the item will be merged upon checkin.

3.) Options and Settings : (Copy Options and Settings from Previous version)

You can copy certain Options dialog box settings from a previous version of Visual Studio .NET to a more recent version visual studio 2003. If you have two different versions of the program installed on the same machine, the first time you launch the newer version of the Visual Studio .NET, a dialog box appears giving you the choice to migrate your existing setting. If you dismiss this dialog, you can display it later by executing the following command from the Windows command line:
devenv /migratesettings
After you migrate your previous Options settings into the new version of Visual Studio .NET, select Options from the Tools menu to display the Options dialog box and review your settings. Most option settings should appear as you last set them.

4.) Web References : (Browsing for XML Web Services)

The Start Browsing for XML Web Services pane in the Add Web Reference Dialog Box now provides Web links to both local and Internet sources of available Web services. Use this pane to locate the desired Web service, then enter a Web reference name to use in your code, and select Add Reference. The new reference will appear in Solution Explorer under the Web References node for the active project.

Web links to sources of available Web services include the following:

Web services on the local machine - select this link to list Web    services available on your own Visual Studio .NET developer machine.
Browse UDDI Servers on the local network - select this link to list   servers with Web services that are available within your local area    network.
UDDI Directory - select this link to search the Microsoft UDDI    Business Registry for businesses that provide Web services.
Test Microsoft UDDI Directory - select this link to list Web services    under development that have been posted for testing.

5.) Build : (Only build startup projects and dependencies on Run)

A new option in visual studio 2003, Only build startup projects and dependencies on Run, has been added to the Projects and Solutions, Environment, Options Dialog Box, under Build and Run Options. When this option is selected, pressing F5 or choosing the Start or Build command from the Debug or Run menu only builds the startup project and its dependencies. When this option is cleared, pressing F5 builds all projects, dependencies, and solution files. This option is cleared by default, but it is enabled when you choose the "Visual C++ Developer" and the " Visual C# Developer" profile on the My Profile tab of the Visual Studio Start Page.
For Visual C++ projects only, three new commands have been placed on a new Project Only submenu of the Build menu:
    Build Only <projectname>
    Rebuild Only <projectname>
    Clean Only <projectname>
These commands build, rebuild, or clean only the C++ project currently selected in Solution Explorer, without building or cleaning any project dependencies or solution files.

6.) Debug : (Debugger Enhancements)

The Visual Studio .NET 2003 debugger has been enhanced by the addition of several new features:

Security enhancements, including a new restriction that    limits Just-In-Time Debugging to the local machine.
Remote debugging using pipes, a new, more secure    alternative to TCP/IP debugging.
SOS, a powerful tool for debugging from the Command    window.
Support for automatically downloading of debug symbols    from a symbol server.
Improved error messages, especially for errors that occur    while debugging web applications.

7.) Deployment : Support for Multiple Versions of the .NET Framework

You can create installers that target a specific version of the .NET Framework using a launch condition that checks for the correct version and redirects the user to a Web location to download if necessary.

8.) Automation Object Model : (Visual C++ .NET 2003)

Visual C++ .NET 2003 features five new property pages for Visual C++ projects:

Managed Resources
XML Data Generator Tool
Managed Wrapper
Auxiliary Managed Wrapper
Primary Interop

In addition to these new property pages, new objects and members were added to the VCProjectEngine assembly to enable users to programmatically manipulate these new property pages and their values, as well as existing property pages.
The new objects are:


9.) Installation : Side-by-Side Installations of Visual Studio .NET

Visual Studio supports installation of versions 2002 and 2003 on the same machine; however you should be aware of certain issues.
Visual Studio .NET 2002 shipped with the Microsoft .NET Framework    SDK version 1.0. Visual Studio .NET 2003 ships with .NET Framework    SDK version 1.1. If you developed applications that reference .NET    Framework version 1.0 and attempt to open the solution in Visual    Studio .NET 2003, the references to .NET Framework are changed to    reference .NET Framework 1.1. You should review the latest .NET    Framework documentation for information on changes that might    affect your application. For more information, see Targeting a .NET    Framework Version and Installation and Setup.
If you open and then save solutions created in Visual Studio .NET    2002 in Visual Studio .NET 2003, you can no longer open the solution    created in version 2002 in Visual Studio .NET 2002.

10.) Help : Preferred Help Collection

In the Help, Environment, Options Dialog Box, a drop-down menu for the Preferred Help Collection option displays the documentation sets available while working in your version of Visual Studio .NET. The default choice, Visual Studio .NET 2003 Combined Help Collection, makes available both the original product documentation and any additional Help collections designed to be integrated with Visual Studio .NET, such as Help for Visual Studio add-ons.

11.) Visual J# :

Microsoft Visual J# can be used by developers who are familiar with the Java-language syntax to build applications and services on the .NET Framework using the Visual Studio .NET 2003 IDE. Visual J# also supports most of the functionality found in Visual J++ 6.0.

12.) Enterprise Instrumentation Framework :

The Enterprise Instrumentation Framework allows unified eventing, logging, and tracing of enterprise applications deployed in a production environment. Applications can be consistently instrumented to publish errors, audits, administrative events, and diagnostic trace events. Operations teams can configure the instrumentation of a running application, including the ability to enable tracing of user requests or business processes through a distributed application.

13.) Tools for Developing for Devices : Smart Device Applications

The Visual Studio .NET integrated development environment now includes tools for developing applications for smart devices, such as the Pocket PC. Using the tools and the .NET Compact Framework, a subset of the .NET Framework, you can create, build, debug, and deploy applications that run on the .NET Compact Framework in personal digital assistants (PDAs), mobile phones, and other resource-constrained devices.

14.) ASP.NET Mobile Designer :

ASP.NET Mobile Designer extends ASP.NET and the .NET Framework, allowing you to build Web applications for mobile phones, PDAs, and pagers. This designer is integrated into the Visual Studio IDE. You can create mobile Web applications, use the Mobile Designer to modify a mobile Web form, and then build and run the application, all from within Visual Studio. For more information, see Getting Started with the ASP.NET Mobile Designer.
