A Lap Around Visual Studio 2010 for C# & VB Developers
A Lap Around VS 2010
•Session Objectives• Discover what’s available• See how to take advantage of new features
•Agenda• New Editor & Shell• C# & VB IDE• C# & VB Language• VS 2010 & .NET 4 Highlights
New Editor & Shell
•WPF User Interface• New Look
•Start Page• View directory, Remove or pin projects, Customize
•Editor• Zoom, Tear off windows, Tab wells, Block selection• Outlining, Collapse from bottom, Hide selection
•Extensibility• VS Gallery, Extension Manager
Code-Focused C# & VB IDE
•Understanding• Highlight References• Type Colorization• Call Hierarchy
•Navigating• Navigate To: Files & Members, Ctrl+,
•Writing & Testing• IntelliSense: Non-aggressive, Substring, PascalCase• Generate From Usage: Type, Method, Property
C# Language
•Syntax Enhancements & Office Development• Named & Optional Parameters• Omit Ref on COM calls• Indexed Properties• Co/contravariance
•Office Deployment: No PIA•Dynamic Language Interop on the DLR
VB Language
•Syntax Enhancements•Multiline Statement Lambdas• Auto-implemented Properties• Collection Initializers• Array Literals• Implicit Line Continuation• Co/contravariance
•Office Deployment: No PIA•Dynamic Language Interop on the DLR
Dynamic Versus Static
DynamicLanguages
Simple and succinct
Implicitly typed
Meta-programming
No compilation
StaticLanguages
Robust
Performant
Intelligent tools
Better scaling
Open Source versus Commercial

ScriptObject calc = GetCalculator();object res = calc.Invoke("Add", 10, 20);int sum = Convert.ToInt32(res);
Dim calc As ScriptObject = GetCalculator()Dim res As Object = calc.Invoke("Add", 10, 20)Dim sum As Integer = Convert.ToInt32(res)
VB 10, C# 4.0 And Dynamic
Calculator calc = GetCalculator();int sum = calc.Add(10, 20);
object calc = GetCalculator();Type calcType = calc.GetType();object res = calcType.InvokeMember("Add", BindingFlags.InvokeMethod, null, new object[] { 10, 20 });int sum = Convert.ToInt32(res);
dynamic calc = GetCalculator();int sum = calc.Add(10, 20);Dynamic
