Visual Studio 2008 Highlights

• Side-by-Side support• Works side-by-side with Visual Studio

2005

• Multi-target Support• .NET framework version 2.0, 3.0 and 3.5• No project model or build changes• Solution can contain projects with

different targets• Enables organizations to move to Visual

Studio 2008 without upgrading all of your source code

Compiler Features

Most are LINQ enablers

XML Literals

Relaxed Delegates

C# 3.0

Extension Methods

Object Initialisers

Anonymous Types

Local Type Inference

Lambda expressions

Collection Initializers

Partial Methods

Automatic Properties

If Ternary Operator

Nullable Syntax

Lambda statements

C# 3.0 Language Innovations

var contacts = from c in customers where c.State == "WA" select new { c.Name, c.Phone };

var contacts = customers .Where(c => c.State == "WA") .Select(c => new { c.Name, c.Phone });

Extension methods

Lambda expressions

Query expressions

Object initializers

Anonymous types

Local variable type

inference

Expression trees

Automatic properties

Partial methods

string name = “Bart”;string reversed = MyExtensions.Reverse(name);

Extension methods• Add methods to existing types “virtually”

• Static method with first “this” parameter• Scoping using namespaces

static class MyExtensions { public static string Reverse(string s) { char[] c = s.ToCharArray(); Array.Reverse(c); return new string(c); }}

string name = “Bart”;string reversed = name.Reverse();

static class MyExtensions { public static string Reverse(this string s) { char[] c = s.ToCharArray(); Array.Reverse(c); return new string(c); }}

Promoted first parameter

Automatic properties• Tired of writing properties?

• Compiler can generate the get/set plumbing

class Customer { private string _name; public string Name { get { return _name; }; set { _name = value; }; }}

class Customer { public string Name { get; set; }}

Setter required; can be private or internal

Object initializers• Ever found the constructor of your taste?

• Insufficient overloads, so pick one• Call various property setters

class Customer { public string Name { get; set; } public int Age { get; set; }}

Customer c = new Customer();c.Name = “Bart”;c.Age = 24;

var c = new Customer(){ Name = “Bart”, Age = 24};

Can be combined with any constructor call

Collection initializers• Arrays easier to initialize than collections?!

int[] ints = new int[] { 1, 2, 3 };List<int> lst = new List<int>();lst.Add(1);lst.Add(2);lst.Add(3);

int[] ints = new int[] { 1, 2, 3 };var lst = new List<int>() { 1, 2, 3 };

Works for any ICollection class by calling its Add

method

Anonymous types• Let the compiler cook up a type

• Can’t be returned from a method• Local variable type inference becomes a must• Used in LINQ query projections

var person = new { Name = “Bart”, Age = 24 };

var customer = new { Id = id, person.Name };

Infers the name of the target property by looking at

the rhs

Lambda expressions• Functional-style anonymous methods

delegate R BinOp<A,B,R>(A a, B b);

int Calc(BinOp<int, int, int> f, int a, int b){ return f(a, b)}

int result = Calc( delegate (int a, int b) { return a + b; }, 1, 2);

var result = Calc((a, b) => a + b, 1, 2);

Parameter types inferred based on the target

delegate

Demo Anonymous types,

automatic properties, collection initializers,

extension methods

First, A Taste of LINQusing System;using System.Query;using System.Collections.Generic; class app { static void Main() {

string[] names = { "Burke", "Connor", "Frank", "Everett", "Albert", "George",

"Harris", "David" };  var expr = from s in names where s.Length == 5 orderby s select s.ToUpper();  foreach (string item in expr) Console.WriteLine(item); }}

Query Expressions

• Introduce SQL-Like Syntax to Language• Compiled to Traditional C# (via Extension Methods)

from itemName in srcExprjoin itemName in srcExpr on keyExpr equals keyExpr

(into itemName)?let itemName = selExprwhere predExprorderby (keyExpr (ascending | descending)?)*select selExprgroup selExpr by keyExpr into itemName query-body

HTML Designer

• New Split View mode• View source and design side by side• Updates in real-time

• Dramatically faster than previous versions• Switch between design, source, or split view with no lag.

CSS Designer

• Dramatically simplifies building and managing CSS styles.• Intuitive visual designer• Summary mode helps troubleshoot/trackdown where styles

are being applied.• Shares same CSS engine as Expression Web

• Developers and designers have access to same features.

ListView

• New data-bound control• Evolution of DataList and Repeater• Designer-friendly

• Full control over markup, including container• Use CSS to style layout

• Bind arbitrary elements (e.g. <select>)

DataPager

• Follows extender model• Add paging to any control that supports it (e.g.

ListView)• Flexible layout – choose from a number of fields to

create a customized pager

ASP.NET AJAX

• Increased productivity• Fewer concepts, fewer lines of code

• Easier to author, debug, and maintain• Well integrated with design and development tools

• Seamlessly integrated application model• Works with ASP.NET pages and server controls

• Works everywhere – cross-browser, standards based

A framework for building richer, more interactive, more personalized web experiences.

Office Business Applications• 2003 & 2007 Support

• 2007 Customisations• Document Level• Application Level• Office Ribbon Designer• Outlook Form Region Designer• Custom & Action Task Panes• Word Content Controls• ClickOnce Deployment and improved Security• VBA <-> VSTO interop• Workflow and SharePoint support

Expand the “Ribbon”

Use full power of Office Excel

Task Pane linked to

business data

Extend the Office Ribbon• New Look and Feel for Office UI

• Replaces Command Bars in “the big 5” Office apps• Introduces a new extensibility model called RibbonX• Enables you to:

• Customize tabs• Add to built-in tabs• Remove tabs, groups, controls• Add to Office menu• Override built-in UI

TabGroup

Control

Rib

bon

Extend the Office Ribbon• Visual Ribbon Designer• Office built-in support for XML-based customization model• VSTO 2005 SE support:• Simplifies hookup from .NET via pre-generated classes and sample XML

• VSTO – Visual Studio 2007 support: • Adds full-blown visual designer support• “Export to XML” option• A more robust programming layer

Property Grid

Ribbon Control Toolbox

Design Surface

Extend the Office RibbonRibbon XML structure requires a specific hierarchy

<customUI xmlns="http://schemas.microsoft.com/office/2006/01/customui" onLoad="OnLoad"> <ribbon> <tabs> <tab idMso="TabAddIns"> <group id="MyGroup" label="My Group"> <toggleButton id="toggleButton1" size="large" label="My Button" screentip="My Button Screentip" onAction="OnToggleButton1" imageMso="AccessFormModalDialog" /> </group> </tab> </tabs> </ribbon></customUI>

For example:

Create Custom Task & Actions Panes• VSTO simplifies and speeds up task pane UI

design process with visual designers and .NET hookup• Actions Pane: • Associated with a specific Word or Excel

document• More robust, easier to program alternative to

Office’s built-in “Smart Document” technology• Custom Task Pane: • The same general idea as Actions Pane, only

on the application add-in level, not individual doc

Add-in frameworkAn add-in is custom code (i.e., a customization) usually written by a third partythat is dynamically loaded and activated by a Host application,based upon some context (e.g., Host startup,

document loading, security, lifetime,…)and typically not tested by the Host

The Add-in provides a service to a Host, Automates a Host, or provides Hosting functionality via public API’s (i.e., Object Model), which are typically made available via an SDK.
