13. 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

14. Multi-targeting in Visual Studio 2008

15. Demo Multi-targeting in VS 2008

16. VB9 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

17. 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

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

19. 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

20. 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

21. Collection initializers Arrays easier to initialize than collections?! int[] ints = new int[] { 1, 2, 3 }; List lst = new List (); lst.Add(1); lst.Add(2); lst.Add(3); int[] ints = new int[] { 1, 2, 3 }; var lst = new List () { 1, 2, 3 }; Works for any ICollection class by calling its Add method

22. 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

23. Lambda expressions Functional-style anonymous methods delegate R BinOp (A a, B b); int Calc(BinOp 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

24. Demo Anonymous types, automatic properties, collection initializers, extension methods

25. First, A Taste of LINQ using 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); } BURKE DAVID FRANK

26. Query Expressions Introduce SQL-Like Syntax to Language Compiled to Traditional C# (via Extension Methods) from itemName in srcExpr join itemName in srcExpr on keyExpr equals keyExpr (into itemName)? let itemName = selExpr where predExpr orderby (keyExpr (ascending | descending)?)* select selExpr group selExpr by keyExpr into itemName query-body

Web Applications ASP.NET 3.5 Microsoft AJAX libraries and project templates ListView, DataPager, LinqDataSource Visual Studio 2008 IDE Enhancements New HTML Designer Shared with Expression Web Rich CSS support, Nested Master Pages Split view with better switching performance Javascript IntelliSense and Debugging

36. 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.

37. 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.

38. 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. )

39. 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

40. 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.

50. Expand the “Ribbon” Use full power of Office Excel Task Pane linked to business data

51. 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 Tab Group Control Ribbon

52. 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

53. Extend the Office Ribbon Ribbon XML structure requires a specific hierarchy <group id="MyGroup" label="My Group"> <toggleButton id="toggleButton1" size="large" label="My Button" screentip="My Button Screentip" onAction="OnToggleButton1" imageMso="AccessFormModalDialog" /> For example:

54. 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

58. Add-in framework An add-in is custom code (i.e., a customization) usually written by a third party that 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.
