22. WPF 4 Data Grid Ribbon Multi-Touch Windows 7 Enhancements

25. 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

27. Open/Closed Principle Software entities should be open for extension, but closed for modification.

28. Known vs. Unknown

30. The Parallel Computing Initiative Letting the brightest developers solve business problems, not concurrency problems. “Concurrency for the masses”

32. Parallel Computing with.NET 4 Task Parallel Library (TPL) Parallel LINQ (PLINQ) Coordination Data Structures (CDS) System.Threading Improvements

33. Parallel LINQ Parallel LINQ (PLINQ) enables developers to easily leverage manycore with a minimal impact to 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 orderby p.Year ascending select p; var q = from p in people where p.Name == queryInfo.Name && p.State == queryInfo.State && p.Year >= yearStart && p.Year <= yearEnd orderby p.Year ascending select p;

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

40. 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

41. However! Primary Interop Assemblies cause many pain points…

42. Go Away, PIA! 1.Compilers embed the portions of the interop assemblies that the add-ins actually use 2.Runtime ensures the embedded definitions of these types are considered equivalent

43. CLR 4 Type Equivalence Scott Hanselman Principal Program Manager Microsoft

45. .NET Framework Compatibility.NET 4.0 is a highly compatible release.NET 4.0 does not auto–roll forward You must add a configuration file with a specific switch to get 3.5 apps to run on 4.0

46. .NET Framework Compatibility Hang on… if 4.0 is compatible, why not run 3.5 apps automatically on 4.0? The BEST thing is always to prefer running on the version of the framework you built against Contact netfxcf@microsoft.com and submit your app for testing!netfxcf@microsoft.com
