15. Windows Communication &Windows Workflow Foundation • Autohost for the hosting of WCF services • WSDL test client allows message injection (beta 2) • Hosting Wizard eases migration of services • New WCF Project templates include both the Autohost and Test Client into an out-of-the-box F5 experience • Simple item template for adding WCF services to an existing Project

17. Windows Communication &Windows Workflow Foundation • Activities to consume WCF services • Function similarly to the InvokeWebService activity available today • Hosting extensions to expose WF workflows as WCF services • Messaging activities (send, receive) • A workflow hosting environment to handle instantiation and message routing

18. Mobile Development • Works side-by-side with Visual Studio 2005 • In-box support for Windows Mobile 5.0 SDKs • Unit Testing Integration with Visual Studio Team System • Security Aware IDE • Device Emulator 3.0

19. Create unit tests for device applications using the VSTS Unit Test infrastructure

20. Ability to target multiple versions of the .NET Compact Framework runtime

21. Device Security Manager makes it easy to deal with complex device security settings Easy to change the device into a specific security setting to test application under different security profiles Better understand current device security settings

22. Device emulator offers the ability to emulate new hardware peripherals Device emulator emulating Windows Embedded CE 6.0 operating system

23. Emulating a low battery scenario. This feature is very helpful for device developers to see how their application will behave in a low battery scenario on a real device

24. Core Language Enhancements

25. Extension Methods Extensionmethod namespace MyStuff { public static class Extensions { public static string Concatenate(this IEnumerable<string> strings, string separator) {…} } } Brings extensions into scope obj.Foo(x, y)  XXX.Foo(obj, x, y) using MyStuff; string[] names = new string[] { "Axel", "Mia", "Niels" }; string s = names.Concatenate(", "); IntelliSense!

26. Object Initializers public class Point { private int x, y; public int X { get { return x; } set { x = value; } } public int Y { get { return y; } set { y = value; } } } Field or property assignments Point a = new Point { X = 0, Y = 1 }; Point a = new Point(); a.X = 0; a.Y = 1;

27. Collection Initializers Must implement IEnumerable Must have public Add method List<int> numbers = new List<int> { 1, 10, 100 }; List<int> numbers = new List<int>(); numbers.Add(1); numbers.Add(10); numbers.Add(100); Add can take more than one parameter Dictionary<int, string> spellings = new Dictionary<int, string> { { 0, "Zero" }, { 1, "One" }, { 2, "Two" }, { 3, "Three" } };

28. Anonymous Types IEnumerable<Contact> phoneListQuery = from c in customers where c.State == "WA" select new Contact { Name = c.Name, Phone = c.Phone }; + public class Contact { public string Name; public string Phone; }

29. Anonymous Types class XXX { public string Name; public string Phone; } IEnumerable<XXX> var phoneListQuery = from c in customers where c.State == "WA" select new { Name = c.Name, Phone = c.Phone }; XXX foreach (var entry in phoneListQuery) { Console.WriteLine(entry.Name); Console.WriteLine(entry.Phone); }

30. Expression TreesCode as Data public delegate bool Predicate<T>(T item); Predicate<Customer> test = c => c.State == "WA"; Predicate<Customer> test = new Predicate<Customer>(XXX); private static bool XXX(Customer c) { return c.State == "WA"; }

31. Expression TreesCode as Data public delegate bool Predicate<T>(T item); Expression<Predicate<Customer>> test = c => c.State == "WA"; ParameterExpression c = Expression.Parameter(typeof(Customer), "c"); Expression expr = Expression.Equal( Expression.Property(c, typeof(Customer).GetProperty("State")), Expression.Constant("WA") ); Expression<Predicate<Customer>> test = Expression.Lambda<Predicate<Customer>>(expr, c);

32. Automatic properties public class Product { public string Name; public decimal Price; }

33. Automatic properties public class Product { string name; decimal price; public string Name { get { return name; } set { name = value; } } public decimal Price { get { return price; } set { price = value; } } }

34. Automatic properties private string □; public string Name { get { return □; } set { □ = value; } } public class Product { public string Name { get; set; } public decimal Price { get; set; } } Must have both get and set

35. C# 3.0 Language Innovations Query expressions var contacts = from c in customers where c.State == "WA" select new { c.Name, c.Phone }; Local variable type inference Lambda expressions var contacts = customers .Where(c => c.State == "WA") .Select(c => new { c.Name, c.Phone }); Extension methods Anonymous types Object initializers

36. Handle Data

37. Problem: Data != Objects

38. <book> <title/> <author/> <year/> <price/> </book> Relational Objects XML The LINQ Project C# 3.0 VB 9.0 Others… .NET Language Integrated Query LINQ toObjects LINQ toDataSets LINQ toSQL LINQ toEntities LINQ toXML

39. LINQ Operators

40. Data Access In APIs Today Queries in quotes SqlConnection c = new SqlConnection(…); c.Open(); SqlCommand cmd = new SqlCommand( @"SELECT c.Name, c.Phone FROM Customers c WHERE c.City = @p0" ); cmd.Parameters.AddWithValue("@po", "London"); DataReader dr = c.Execute(cmd); while (dr.Read()) { string name = dr.GetString(0); string phone = dr.GetString(1); DateTime date = dr.GetDateTime(2); } dr.Close(); Arguments loosely bound Results loosely typed Compiler cannot help catch mistakes

41. Data Access with LINQ public class Customer { public int Id; public string Name; public string City; public string Phone; } ---------------------------- GridView1.DataSource = from customer in db.Customers where customer.City == "London" select customer; GridView1.DataBind(); Classes describe data Query is natural part of the language The compiler provides IntelliSense and type-checking

42. LINQ Architecture Others… C# VB .Net Language Integrated Query (LINQ) LINQ enabled data sources LINQ enabled ADO.NET LINQ To XML LINQ To Datasets LINQ To SQL LINQ To Entities LINQ To Objects <book> <title/> <author/> <price/> </book> Relational XML Objects

43. LINQ Basics • Query Operators can be used against any .NET collection (IEnumerable<T>) • Built-in examples: Select, Where, GroupBy, Join, etc. • Extensibility model supports adding/replacing them • Query Expressions can operate on information sources and apply query operators against them to return IEnumerable<T> sequences

44. Searching/Sorting an Array Array implements IEnumerable<T> • string [] cities = { “Auckland”, “Oslo”, “Sydney”, • “Seattle”, “Paris”, “Los Angeles” }; • IEnumerable<string> places = from city in cities • where city.Length > 5 • orderby city descending • select city; • GridView1.DataSource = places; • GridView1.DataBind(); LINQ Query Expression using Query Operators IEnumerable<string> sequence result can be used w/ databinding

45. Projections • Sometimes you want to modify or transform the data you return from a query • LINQ enables powerful “data shaping” scenarios using projections • Can optionally be used in conjunction with new “anonymous type” compiler support

46. Projections w/ Anonymous Types List<City> cities = CityUtilityHelper.GetCities(); var places = from city in cities where city.DistanceFromSeattle > 1000 select new { City = city.Name, Country = city.Country, DistanceInKm = city.DistanceFromSeattle * 1.61 }; GridView1.DataSource = places; GridView1.DataBind(); Anonymous type used to custom shape data results and apply miles->kilometer conversion

47. Projections w/ Anonymous Types <asp:GridView ID="GridView1" AutoGenerateColumns="false" runat="server"> <Columns> <asp:BoundField HeaderText="Country" DataField="Country" /> <asp:BoundField HeaderText="City" DataField=“City" /> <asp:BoundField HeaderText="Dist (KM)" DataField="DistanceInKm" /> </Columns> </asp:GridView>

48. LINQ for SQL • Maps .NET classes to relational SQL data • Translates LINQ queries to SQL execution • Supports change tracking for insert, update, delete operations • Built on top of ADO.NET and integrates with connection-pooling and transactions

49. LINQ for SQL Basics public partial class Product { public int ProductID; public string ProductName; public Nullable<int> SupplierID; public Nullable<int> CategoryID; } public class NorthwindDataContext : DataContext { public Table<Product> Products; } NorthwindDataContext db = new NorthwindDataContext(); DataList1.DataSource = from product in db.Products where product.UnitsInStock > 0 select product; DataList1.DataBind();
