11 ASP.NET: Future Directions Developing Rich Web Applications With “Atlas”

12 ASP.NET “Atlas” Goals Increased productivity Fewer concepts, fewer lines of code Application and UI building blocks for common scenarios Easier to author, debug, and maintain Clean separation of content, style, behavior, and code Well integrated with design and development tools Seamlessly integrated application model Works with ASP.NET pages and server controls Allows access to ASP.NET-hosted web services and components Works everywhere – cross-browser, standards based A FRAMEWORK FOR BUILDING RICHER, MORE INTERACTIVE, MORE PERSONALIZED WEB EXPERIENCES A FRAMEWORK FOR BUILDING RICHER, MORE INTERACTIVE, MORE PERSONALIZED WEB EXPERIENCES

13 “Atlas” Architecture ‘Atlas” Client Script Library Built-in Controls and Behaviors Built-in Controls and Behaviors Script Core Base Class Library Component and UI Model Browser Compatibility “Atlas” Client Application Services Local Store Browser Integration Browser Integration ASP.NET “Atlas” Server Extensions “Atlas” Server Controls “Atlas” Server Controls ASP.NET “Atlas” Application Services “Atlas” Web Services Bridge “Atlas” Web Services Bridge ASP.NET 2.0 ASP.NET Application Services ASP.NET Application Services Page Framework And Server Controls Page Framework And Server Controls “Atlas”-enabled ASP.NET Pages “Atlas”-enabled ASP.NET-hosted Web Services (ASMX or WCF) ASP.NET-hosted Web Services (ASMX or WCF) ASP.NET “Atlas” Server “Atlas” HTML Page Page “Atlas”ServiceProxies“Atlas”ServiceProxies “Atlas” Client

14 Script-Based Type System Scenario: Script code can be ad-hoc, unmaintainable, etc. Solution: Encapsulate data and logic into classes and components Expose intuitive object model “Atlas” OOP constructs built on top of standard script constructs and techniques Namespaces Classes, Interfaces, and inheritance Properties, methods, events Private and public members Delegates Enumerations and Flags

15 API Samples var myArray = new Array(‘abc’, ‘ghi’); myArray.push(‘jkl’); myArray.splice(1, 0, ‘def’); var myObject =...; var s = ‘’; for (var name in myObject) { var value = myObject[name]; s += name + ‘ = ‘ + value + ‘\r\n’; } var myArray = new Array(‘abc’, ‘ghi’); myArray.add(‘jkl’); myArray.insert(1, ‘def’); var myObject =...; var s = ‘’; for (var name in myObject) { var value = myObject[name]; var value = myObject[name]; s += String.Format(‘{0} = {1}\r\n’, s += String.Format(‘{0} = {1}\r\n’, name, value, value.length); name, value, value.length);} var myObject = ‘...’; var sb = new Web.StringBuilder(); for (var name in myObject) { var value = myObject[name]; var value = myObject[name]; sb.append(name); sb.append(name); sb.append(‘ = ‘); sb.append(‘ = ‘); sb.appendLine(value); sb.appendLine(value);} var s = sb.toString();

34 The.NET Language C# 3.0 Integrated Query Project

35 Getting productive Today we program against relational and hierarchical data using a language that does not support this natively Data != Objects We are busy describing how things need to get done in stead of what we want

36 C# 3.0 Design Goals Integrate objects, relational, and XML Build on foundation laid in C# 1.0 and 2.0 Run on the.NET 2.0 (“Whidbey”) CLR Remain 100% backwards compatible

37 The LINQ Project Standard Query Operators Objects DLinq (ADO.NET) XLinq(System.Xml) XML.NET Language Integrated Query C# 3.0 VB 9.0 Others… SQLWinFS

38 LINQ Style programming var contacts = from c in customers from c in customers where c.State == "WA" where c.State == "WA" select new { c.Name, c.Phone }; select new { c.Name, c.Phone }; class Contact { … }; List contacts = new List (); foreach(Customer c in customers) { if(c.State == “WA”) { Contact ct = new Contact(); Contact ct = new Contact(); ct.Name = c.Name; ct.Name = c.Name; ct.Phone = c.Phone; ct.Phone = c.Phone; contacts.Add(ct); contacts.Add(ct);}}

39 Query Expressions Language integrated query syntax from id in source { from id in source | where condition } [ orderby ordering, ordering, … ] select expr | group expr by key [ into id query ]

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

41 Standard Query Operators RestrictionWhere Projection Select, SelectMany Ordering OrderBy, ThenBy GroupingGroupBy Quantifiers Any, All Partitioning Take, Skip, TakeWhile, SkipWhile Sets Distinct, Union, Intersect, Except Elements First, FirstOrDefault, ElementAt Aggregation Count, Sum, Min, Max, Average Conversion ToArray, ToList, ToDictionary CastingOfType<T>

42 DLinq For Relational Data SqlConnection c = new SqlConnection(…); c.Open(); SqlCommand cmd = new c.Name, c.Name, c.Phone FROM Customers c FROM Customers c WHERE c.City WHERE c.City "London“); DataReader dr = c.Execute(cmd); while (dr.Read()) { string name = dr.GetString(0); string name = dr.GetString(0); string phone = dr.GetString(1); string phone = dr.GetString(1); DateTime date = dr.GetDateTime(2); DateTime date = dr.GetDateTime(2);}dr.Close(); Accessing data today Queries in quotes Loosely bound arguments Loosely typed result sets No compile time checks

43 public class Customer { … } public class Northwind: DataContext { public Table Customers; public Table Customers; …} Northwind db = new Northwind(…); var contacts = from c in db.Customers from c in db.Customers where c.City == "London" where c.City == "London" select new { c.Name, c.Phone }; select new { c.Name, c.Phone }; DLinq For Relational Data Accessing data with DLinq Classes describe data Strongly typed connection Integrated query syntax Strongly typed results Tables are like collections

44 XLinq For XML Data XmlDocument doc = new XmlDocument(); XmlElement contacts = doc.CreateElement("contacts"); foreach (Customer c in customers) if (c.Country == "USA") { if (c.Country == "USA") { XmlElement e = doc.CreateElement("contact"); XmlElement e = doc.CreateElement("contact"); XmlElement name = doc.CreateElement("name"); XmlElement name = doc.CreateElement("name"); name.InnerText = c.CompanyName; name.InnerText = c.CompanyName; e.AppendChild(name); e.AppendChild(name); XmlElement phone = doc.CreateElement("phone"); XmlElement phone = doc.CreateElement("phone"); phone.InnerText = c.Phone; phone.InnerText = c.Phone; e.AppendChild(phone); e.AppendChild(phone); contacts.AppendChild(e); contacts.AppendChild(e); }doc.AppendChild(contacts); Programming XML today <contacts> Great Lakes Food Great Lakes Food (503) (503) …</contacts> Imperative model Document centric No integrated queries Memory intensive

45 XLinq For XML Data XElement contacts = new XElement("contacts", from c in customers from c in customers where c.Country == "USA" where c.Country == "USA" select new XElement("contact", select new XElement("contact", new XElement("name", c.CompanyName), new XElement("name", c.CompanyName), new XElement("phone", c.Phone) new XElement("phone", c.Phone) )); Programming XML with XLinq Declarative model <contacts> Great Lakes Food Great Lakes Food (503) (503) …</contacts> Element centric Integrated queries Smaller and faster

46 XLinq For XML Data Language integrated query for XML Expressive power of XPath / XQuery But with C# or VB as programming language Leverages experience with DOM Element centric, not document centric Functional construction Text nodes are just strings Simplified XML namespace support Faster and smaller

47 Benefits Of LINQ Unified querying of objects, relational, XML Type checking and IntelliSense for queries SQL and XQuery-like power in C# and VB Extensibility model for languages / APIs Describe What, not how boosts productivity
