  10. Multi-targetting What’s New In VS 2008? ( video ) Languages + LINQ VS 2008

  11. .NET Fx 2.0 Multitargetting .NET Fx 3.0 • No longer a hard link between Visual Studio and the application’s target framework .NET Fx 3.5 VS 2008

  12. multitargetting demo

  13. Language Features in VS 2008 Most are LINQ enablers C# 3 VB9 Anonymous Types XML Literals Collection Initialisers Extension Methods Relaxed Delegates Automatic Properties Lambda expressions If Ternary Operator Lambda statements Object Initialisers Nullable Syntax Local Type Inference Partial Methods

  14. C# 3.0 language features demo

  15. Language INtegrated Query? • Lots of code written today in order to loop, filter, sort, group, etc. • Why not build better support for this? sort sum loop

  16. Why Have LINQ? • Access to common data like XML or SQL is harder than accessing in memory objects; • Why not have better API’s than this? hope! pray! hope!

  17. Language Integrated Query fromdatainsomeDataSource joinotherDatainsomeOtherSource onkeyExprequalskeyExpr(intoitemName)? letsomeVariable= someExpression wheresomePredicate orderby (expression(ascending | descending)?)* selectexpression groupexpressionbykeyExpression intoitemName Language Features ( C# V3 and VB V9 ) .NET Framework V3.5 Custom Objects XML SQL

  18. LINQ to objects demo

  19. How Does LINQ Work? • Compiler rewrites as method calls • No need to implement Select() etc. if myData is either IEnumerable IQueryable • Implementations already present in the .NET Framework for those cases

  20. IEnumerable & IQueryable? • IEnumerable – query executed serially, one operator at a time where select Execute Execute • IQueryable – whole query passed to implementation for execution where select Capture & Execute

  21. Queryablevs Enumerable demo

  22. LINQ in .NET Framework V3.5
