Lap Around Visual Studio 2008 and the .NET Framework 3.5 Brian H. Prince Director, Application Development Consulting Practice Quick Solutions, Inc. This material was adopted from the VS2008 training kit.
Agenda • .NET Framework & Visual Studio Roadmap • .NET Framework 3.5 overview • Visual Studio design goals • Lap around new features
What is the .NET Framework 3.5? .NET Framework 3.5 CLR Add-in Framework LINQ ASP.NET 3.5 Additional Enhancements .NET Framework 3.0 + SP1 Windows Presentation Foundation Windows Communication Foundation Windows Workflow Foundation Windows CardSpace .NET Framework 2.0 + SP1
.NET Framework & VS Roadmap RTM 3.0 Major Releases • “Rosario” 3.5 RTM • VS 2008 Beta 2 • .NET Framework 3.5 Beta 2 • VS Extensions for WF • VS Extensions for WCF/WPF CTP ASP.NET AJAX 1.0 Out of band Releases 2006 2007 2008
Visual Studio 2008 Design Goals • Best tool set for Windows Server 2008, Windows Vista and Microsoft Office 2007 • .NET Framework 3.5 design surfaces • Office 2007 support including ClickOnce and VSTO • MFC support for Vista common controls • Improvements for Web Developers • HTML / CSS designer enhancements • Integrated AJAX and JavaScript support • Language advances • .NET Framework multi-targeting support • Improved Data & Language integration in VB / C#
Visual Studio Enhancements • Multi-targeting • Target multiple versions of the framework from a single tool - Visual Studio 2008 • Supports framework versions 2.0, 3.0, and 3.5 • Enables only features available in target framework • Toolbox, Project types, References, Intellisense, … • Making is easy to upgrade to Visual Studio 2008 • Unit Testing • Now available in all editions of Visual Studio Professional
Lifecycle Tools Enhancements • Team Foundation Server 2008 • Built-in support for Continuous Integration • TFS Migration Toolkit • “Get latest on checkout” • Annotate • Folder Diff • For developers: • Code metrics • Performance “hotpathing” • Profiler baselining • Much faster unit testing performance • For testers: • Load testing support for AJAX applications • Better UI for load test monitoring / reporting • And much more…
C# 3.5 Local Variable Type Inference • Object Initializers • Collection Initializers • Anonymous Types • Auto-Implemented Properties • Extension Methods • Lambdas • Query Expressions • Expression Trees • Partial Methods
Object Initializers Person p = new Person() { FirstName = "John", LastName = "Doe“}; Person p = new Person() p.FirstName = “John”; p.LastName = “Doe”;
Collection Initializers var cookies = new List<Cookie> { new Cookie("cookie1", "1"), new Cookie("cookie2", "2") };
Local Variable Type Inference Person aPerson = new Person(24); varaPerson = new Person(24);
Anonymous Types public class Cust { public intCustId { get; set; } private string _CustName; public string CustName { get { return _CustName; } set { _CustName = value; } } } varobj = new { CustId = 1, CustName = "C#" };
Auto-Implemented Properties private string _Test1;public string Test1 { get { return _Test1; } set { _Test1 = value; } } public string Test { get; set; }
Extension Methods • Extension methods will allow us to extend existing classes with new functionality. • In C++ these are called ‘non member functions’ public static string SuperUpper (this string s) { Return s.ToUpper(); }
Other Stuff • Lambda Expressions • Expression Trees • Partial Methods • …
Visual Basic 9.0 Features • Query expressions • XML literals • XML element access • Nullable types • Object initializers • Local type inference • Lambda Expressions Extension methods Expression trees Anonymous types Ternary Operator Coalesce Operator Relaxed Delegates Partial Methods …and many other IDE improvements, bug fixes, and small features!
Interop Forms Toolkit • Strategy - Phased Upgrades using Interop • Reduce Risk by moving one Form at a time • Extend existing assets with VB.NET • Microsoft Interop Forms Toolkit (v2.0) • Guidance, tools, and code to make upgrades easier • Not a code converter! VB6 Application Interop (COM) VB.NET Form(s) VB6 Form(s)
Language INtegrated Query (LINQ) New programming model for data access that integrates query support directly within the .NET languages • Designed to reduce the complexity when working with data • Query operators can be used against any collection • Built-in examples: Select, Where, GroupBy, Join, etc. • Extensibility model supports extending/replacing these • Benefits • Work with data in a consistent way, regardless of the type of data • Interact with data as objects • Better integration with programming languages • Improved productivity through IntelliSense in Visual Studio
LINQ Architecture & Components C# 3.0 VB 9.0 Others… .NET Language Integrated Query LINQ toObjects LINQ toDataSets LINQ toSQL LINQ toXML <book> <title/> <author/> <year/> <price/> </book> Objects Relational XML
