  7. The Two Faces of Visual Studio 2010 Visual Studio As An Editor Visual Studio As A Platform

  8. … As An Editor An improved focus on… Writing code, Understanding code, Navigating code, Publishing code

  9. Demo

  10. … As A Platform New Extensible Editor allows editor to be easily extended to provide a rich and robust editing experience Online Visual Studio Gallery integrated directly into Visual Studio

  11. … As A Platform Enabling the Visual Studio Ecosystem through: Online Templates Extensions and Extension Manager All Contributable by Community

  12. Demo

  13. The VS2010 Roadmap • Beta 2, October 19th, 2009 • RTM, March 22nd, 2010

  14. What’s new in .Net 4.0and C# 4.0

  15. What’s new in .Net4.0 and C# 4.0 • .Net Framework - A Brief Review • .Net Framework 4.0 Highlights • Managed Extensibility Framework (MEF) • Managed Languages • C# 4.0 New Features • Dynamic Language Runtime (DLR) • F#

  16. The .NET Framework WPF Win Forms DLR ASP.NET WCF LINQ And more! Base Class Libraries The CLR JIT & NGEN Garbage Collector Security Model Exception Handling Loader & Binder

  17. A Look Back… SP1 3.5 3.0 .NET 1.0 .NET 1.1 .NET 2.0 .NET 4 2002 2003 2005-08 2008 CTP CLR 1.0 CLR 1.1 CLR 2.0 CLR 4

  18. Web Applications Client Applications Web Forms 4 AJAX 4 WPF 4 MEF Client/Server WCF 4

  19. Managed Extensibility Framework • The Managed Extensibility Framework (MEF) is a new library in the .NET Framework that enables greater reuse of applications and components. • Using MEF, .NET applications can make the shift from being statically compiled to dynamically composed

  20. Managed Languages Today Our managed languages are starting to share some very similar features: Functional Concise Declarative

  21. Why Declarative Matters… What How Imperative Declarative

  22. LINQ, The Power of Declarative IList<Person> FindParentsWithChildNamed(string childName) { var matches = new List<Person>(); foreach(var person in _people) { foreach(var child in person.Children) { if (child.Name.Equals(childName)) { matches.Add(person); break; } } } return matches; } Before

  23. LINQ, The Power of Declarative IList<Person> FindParentsWithChildNamed(string childName) { var matches = from person in people from child in person.Children where child.Name.Equals(childName) select person; return matches.ToList(); } After

  24. Parallel LINQ Parallel LINQ (PLINQ)enables developers to easily leveragemanycore with a minimal impactto existing LINQ programming model var q = from p in people         where p.Name == queryInfo.Name && p.State == queryInfo.State && p.Year >= yearStart && p.Year <= yearEnd orderbyp.Year ascending         select p; .AsParallel()

  25. Addressing Language Trends

  26. The Evolution of C# C# 4.0 Dynamic C# 3.0 LINQ C# 2.0 Generics C# 1.0 Managed Code

  27. New C# 4.0 Features • Late-Binding Support • Named and Optional Parameters • Improved COM Interop • Covariance and Contravariance

  28. Named and Optional Parameters • Consider this example: public void M(int x, int y = 5, int z = 7) { } • In this method, the parameters y and z are assigned default values. Calls to this method might look like this: M(1, 2, 3); // ordinary call of MM(1, 2); // omitting z – equivalent to M(1, 2, 7)M(1);  // omitting both y and z – equivalent to M(1, 5, 7)M(1, z: 3); // passing z by nameM(x: 1, z: 3); // passing both x and z by nameM(z: 3, x: 1); // reversing the order of arguments

  29. Type Equivalence Interop Assemblies translate between managed code and COM For each interface, struct, enum, delegate, and member, contains a managed equivalent with marshalling data

  30. However Primary Interop Assemblies cause many pain points…

  31. NO PIA • Compilers embed the portions of the interop assemblies that the add-ins actually use • Runtime ensuresthe embedded definitions of these types are considered equivalent

  32. Simplifying Your Code with C# 4.0

  33. Why a “Dynamic Language Runtime”? Dynamically-Typed Ruby Python Statically-Typed VB C# Common Language Runtime

  34. Why a “Dynamic Language Runtime”? Dynamically-Typed Ruby Python Statically-Typed VB Dynamic Language Runtime C# Common Language Runtime

  35. .NET Dynamic Programming IronPython IronRuby C# VB.NET Others… Dynamic Language Runtime Expression Trees Dynamic Dispatch Call Site Caching PythonBinder RubyBinder ObjectBinder JScriptBinder COMBinder

  36. Dynamically Typed Objects Calculator calc = GetCalculator(); int sum = calc.Add(10, 20); object calc = GetCalculator(); TypecalcType = calc.GetType(); object res = calcType.InvokeMember("Add", BindingFlags.InvokeMethod, null, newobject[] { 10, 20 }); int sum = Convert.ToInt32(res); ScriptObject calc = GetCalculator(); object res = calc.Invoke("Add", 10, 20); int sum = Convert.ToInt32(res); Statically typed to be dynamic dynamic calc = GetCalculator(); int sum = calc.Add(10, 20); Dynamic conversion Dynamic method invocation

  37. Dynamic Language Interop

  38. F# in VS2010 • F# is .NET managed programming language combining functional programming and object-oriented programming. • It’s ideally suited for parallel, algorithmic, technical and explorative development • F# is a strongly-typed language like C#, but with a lightweight syntax often seen in a dynamic language like Python

  39. F# Features • “Programming in The Small” with Tuples and functions • Simple, and more error-free asynchronous programming • Strong types for floating point code • Integrated with Visual Studio 2010

  40. Syntax Sample let data = (1,2,3) let rotations (x, y, z) = [ (x, y, z); (z, x, y); (y, z, x) ] let derivative f x = let p1 = f (x - 0.05) let p2 = f (x + 0.05) (p2 - p1) / 0.1 let f x = 2.0*x*x - 6.0*x + 3.0 let df = derivative f System.Console.WriteLine("The derivative of f at x=4 is {0}", df 4.0)

  41. Parallel and Asynchronous Programming with F# let http url = async { let req = WebRequest.Create(Uri url) let! resp = req.AsyncGetResponse() let stream = resp.GetResponseStream() let reader = new StreamReader(stream) let! contents = reader.AsyncReadToEnd() return contents } let sites = ["http://bing.com"; "http://microsoft.com"; "http://msdn.com"; "http://msnbc.com"] let htmlOfSites = Async.Parallel [for site in sites -> http(site)] |> Async.RunSynchronously
