Application Lifecycle Management

The Application Lifecycle Management client application is

now available in all versions of Visual Studio (excluding

Express versions). Application Lifecycle Management

includes version control, work item tracking, build

automation, a team portal, reporting and business

intelligence, Agile Planning Workbooks, and test case

managementeverything that you need to collaborate on

your software development projects. Application Lifecycle

Management is included in Visual Studio 2010 with one

Client Access License (CAL). You can purchase additional

Client Access Licenses as needed. For more information,

see What's New for Application Lifecycle Management in

Visual Studio 2010.

Code Generation and Text Templates

Text templates can be created and used in any version of

Visual Studio, without the need for any other

component. Generating any kind of text file from your

application has been made easier in Visual Studio 2010

with the introduction of Preprocessed Text Templates.

Support for code generation has also been

improved through better integration with the build

system, so that your generated source code is always up

to date after any change to the source model. For more

information, see Code Generation and Text Templates.

Start Page

The Visual Studio 2010 Start Page features a new look

and new functionality. A tabbed content area links to a

variety of selected and categorized learning resources.

This includes MSDN resources, community resources, and

a customizable news feed. An improved Recent Projects

list lets you add projects to the list or remove them with a

single mouse click. You can also install custom Start Pages

from Extension Manager. For more information about the

Start Page, see Start Page.

Extension Manager

You can find and install Visual Studio extensions from the

IDE by clicking Extension Manager on the Tools menu.

Extension Manager downloads and installs community-

published extensions from the Visual Studio Gallery Web

site without requiring that you open a browser. It also

enables you to uninstall, disable, or re-enable installed

extensions. For more information, see Installing and

Managing Visual Studio Extensions.

New Project Dialog Box

The New Project dialog box in Visual Studio

2010 includes the same search and install capabilities as

the Extension Manager, except that it searches only for

project templates and item templates. For more

New Help Viewer

The Help Viewer has been completely redesigned for

Visual Studio 2010. You can view documentation online or

offline by using your preferred Web browser, download

the latest documentation on demand, navigate the

documentation by using a simplified table of contents,

search for specific content by using an improved full-textsearch algorithm, and use a more streamlined F1 system

to locate content specific to the task that you are working

on. For more information, see Microsoft Help System

Documentation.

In Visual Studio 2010, the Visual Basic and C# languages

continue to move toward feature parity. This enables you

to choose a language based on personal preferences

because both languages are equally capable. This section

lists some of the new features in C# and Visual Basic.

Visual Basic Language

Visual Basic has new features that shorten syntax and

enable you to write code faster. These features include

auto-implemented properties, implicit line continuation,

collection initializers, and single- and multi-statement

lamdba expressions. Additionally, Visual Basic now

supports simplified deployment through type equivalence.

For more information, see What's New in Visual Basic

2010.

C# Language

The new features in the C# language work together to

simplify programming with the Microsoft Office APIs. With

named and optional arguments, you no longer have to

specify values for every optional parameter when you call

COM methods. With dynamic support, you can reference

any object, such as return values from COM APIs or

dynamic languages, without using an explicit type cast.

Indexed properties and optional ref modifiers facilitate

access to COM interfaces. Also, type equivalence support

simplifies deployment by embedding types from primary

interop assemblies (PIAs) directly in your assembly. For

more information, see What's New in Visual C# 2010.

Visual Studio 2010 includes F#, a new .NET Framework

language that supports functional programming and

traditional object-oriented and imperative (procedural)

programming. F# combines the succinct, expressive, and

compositional style of functional programming with the

runtime, libraries, interoperability, and object model of

the .NET Framework. In other words, you get the best ofboth paradigms. For more information, see Visual F#.

Data Access and Modeling

Web Development

Visual Studio 2010 includes project templates and tools

that you can use to create solutions that extend Microsoft

Office 2010 and the 2007 Microsoft Office system. You can

take advantage of new development features for Office

projects, such as expanded Ribbon Designer support for

Microsoft Office 2010 applications and the ability to create

Office solutions that do not require the Office primary

interop assemblies on end user computers. You can also

use new deployment features in Office projects, such as

the ability to deploy Office solutions to all users on a

computer. For more information, see Office Development

in Visual Studio and What's New in Office Development.

.NET Framework 4 includes enhancements to the

ADO.NET Entity Framework that further decrease the

amount of coding and maintenance required for

data-driven applications. In Visual Studio 2010, improved

flexibility and customization options in the ADO.NET

Entity Data Model Tools make it easier to create EntityFramework applications. For more information, see

ADO.NET Entity Framework and ADO.NET Entity Data

Model Tools.

Visual Studio 2010 includes improvements that speed up

code authoring, simplify Web deployment, and more.

Faster Code Authoring

Code Snippets

Visual Studio 2010 includes Code Snippets for

HTML, JScript, and ASP.NET controls to help you

write code faster. You can insert snippets from the

Code Snippets Manager or directly from

IntelliSense.

Dramatically Improved IntelliSense for JScript

IntelliSense now parses 2 to 5 times faster, so

there is virtually no processing delay, even

with large script libraries.

IntelliSense accepts diverse coding styles so

that you get full IntelliSense support for

almost every library.

IntelliSense displays XML documentation

comments as you type.

For more information, see Creating and Using IntelliSense

Code Snippets.

Simplified Web Deployment

With Visual Studio 2010, you can package and publish

your Web application in one click.

WPF and Silverlight Designer

, ,

enables you to package your Web application for

deployment to an Internet Information Services

(IIS) Web server. A Web package is a .zip file or a

folder structure that includes everything a Web

server needs to host your application. It contains

Web content, IIS settings, database scripts,

components, registry settings, and certificates. The

Web Deployment Tool has been integrated into

Visual Studio and enables you to create Webpackages with one click.

One-Click Publishing

You can now publish to a server by using the Web

Deployment Tool, FTP, folder copying, or FrontPage

Server Extensions in one click. Visual Studio stores

all the setting information, such as publish method,

server information, and user credentials.

Web Configuration Transformations

You can now configure your project to transform theweb.config file during deployment. When you deploy

the project, the settings in web.config automatically

match the settings on your debug, staging, and

production servers.

For more information, see ASP.NET Web Application

Project Deployment Overview.

Other Additions

Visual Studio 2010 also includes new features for ASP.NET

and support for MVC-Based Web applications. For more

information, see What's New in ASP.NET 4 and Visual Web

Developer.

In Visual Studio 2010, various designer improvements

have been made to help you create Windows Presentation

Foundation (WPF) and Silverlight applications.

Improved Support for Silverlight

In Visual Studio 2008, the designer support for Silverlightprojects is limited to a read-only Preview window. In

Visual Studio 2010, the designer support is the same for

Silverlight as it is for WPF projects. For example, in

Silverlight projects you can now select and position items

with a mouse on the designer surface. For more

information, see Windows Presentation Foundation in

Visual Studio.

Drag-and-Drop Data Binding for WPF

After you add a data source to your project, you can

generate data-bound Windows Presentation Foundation

(WPF) controls by dragging items from the Data Sources

window to the WPF Designer. For more information, see

Binding WPF Controls to Data in Visual Studio.

Visualizing WPF objects

7/9

Visual C++ Development

The debugger in Visual Studio 2010 includes the WPF Tree

visualizer, which displays WPF objects in a more useful

way. When you invoke the visualizer on a WPF object

from the Watch window, you see the object displayed as a

tree and a list of properties. For more information, see

How to: Use the WPF Tree Visualizer.

Following are some of the new Visual C++ features.

Improved User Experience

A number of improvements have been made to make the

Visual C++ IDE more responsive, especially when you

work with large applications. Many IDE components, such

as the IntelliSense engine, now parse and process files in

the background. You no longer have to wait for Visual

Studio to re-process the whole project every time that you

modify a header file, switch between project elements, or

reconfigure your project from debug to release.

The new IntelliSense is more accurate because it handles

advanced C++ code constructs and conditionally defined

macros that the old version could not handle.

Improved IntelliSense Error Reporting

In earlier versions of Visual Studio, it can be unclear why

IntelliSense fails for a line of code. In Visual Studio 2010,

the IDE detects code that will cause a loss of IntelliSense

and underlines that code with a red wavy line. In addition,

the IDE reports any IntelliSense errors to the Error

List window. You can double-click the error in the Error

List window to go to the code that is causing a problem.

#include Automatic Completion

The IDE now supports automatic completion for the

#include keyword. When you type #include, the IDE

creates a list of valid header files. As you continue typing,

the IDE filters the list based on your typing. At any time,

you can select the file that you want to include. This

enables you to quickly include files without knowing the

exact file name.

Targeting of Specific Compilers and Libraries

In Visual Studio 2010, Visual C++ projects can target

either the toolset in Visual Studio 2010 or the toolset in

Visual Studio 2008. This enables you to take advantage of

the IDE enhancements in Visual Studio 2010 while you

continue to use an earlier version of the Visual C++

libraries and compiler. To switch between toolsets, you are

only required to change one property in your project file.

For more information, see General Property Page

(Project).

MFC Class Wizard

In Visual Studio 2010, the MFC Class Wizard

is reintroduced. This wizard can be started from anywhere

in your solution. It enables you to add classes, messages,

and variables without having to manually change

individual code files.

Build Improvements

Visual C++ projects use a new file format (.vcxproj) that

replaces the old format (.vcproj). To build projects, you

now use MSBuild.exe instead of VCBuild.exe. MSBuild,

which is the build platform for Microsoft, provides several

benefits, including better diagnostics, extensibility, andintegration. For more information, see MSBuild (Visual

C++).

Restart Manager Support

Visual Studio now supports the restart manager in

Microsoft Foundation Classes (MFC) applications. The

restart manager is a Windows feature that protects users

against accidental data loss by regularly saving open

documents. If your application stops unexpectedly, the

restart manager restarts the application and gives the

user the option of restoring the automatically saved data.You can add this functionality to an existing application by

adding just one line of code and recompiling. By using the

restart manager, you can greatly reduce the chances of

accidental data loss in your applications. For more

information, see How to: Add Restart Manager Support.

New C++0x Language Features

The Visual C++ compiler introduces five new features to

support the C++0x standard: lambda expressions, rvalue

references, compile-time assertions, expression type

discovery, and automatic type deduction. For more

information, see What's New in Visual C++ 2010.

You can now write programs that distribute work across

multiple processors without having to work directly with

threads or the thread pool. Visual Studio 2010 includes

parallel computing libraries for both the C runtime library

(CRT) and the .NET Framework. You can also debug native

and managed applications by using the new

multithreading tools in the Visual Studio debugger. For

more information, see the Parallel Computing DeveloperCenter Web site.

Parallel Programming in the .NET Framework

.NET Framework 4 includes new libraries that support task

and data parallelism, a parallel implementation of LINQ to

Objects called Parallel Language Integrated Query

(PLINQ), and various new data types for synchronization

and concurrency. These libraries rely on a new task

scheduler that is integrated with the .NET Framework

thread pool. For more information, see Parallel

Programming in the .NET Framework.

Parallel Programming in Visual C++

The C runtime library now includes the Concurrency

Runtime, which is a concurrent programming
