VS2008 & .NET V3.5 RecapJavascript Debugging, XElement class for building XML, ListView - a powerful designer supported repeater control, Javascript Debugging, additional refactorings, SQL DB publishing, Ajax is a first class citizen, IQueryable, and Javascript Debugging

Anonymous types var dt = DateTime.Today; var anon = new { Name = "Terry", Age = 34 };

Automatic Properties public string FirstName {get; set;} public int Age { get; private set; }

Object Initalizers Person person = new Person { FirstName="Chris", LastName="Green", Age=33 };

Collection Initalizers List<Person> people = new List<Person> { new Person { FirstName = "Chris", LastName = "Green", Age = 33 }, ... };

Extension Methods public static int LastDay (this DateTime dt) { return DateTime.DaysInMonth(dt.Year, dt.Month); }

Lambda Expressions Func<int, int> Square = x => x * x; int nSquare = Square(5); int[] numbers = { 5, 4, 1, 3 }; int oddNumbers = numbers.Count(n => n % 2 == 1);

LINQ var initials = from person in people where person.City == "Galway“ select person.FirstName.Remove(1) + person.LastName.Remove(1);

Did I mention Javascript Debugging?

VS2008 & .NET V3.5 SP 1 Overview

ADO.NET Entity Framework releaseVery similar to Linq To SQL

Generate data model

conceptual model < mapping > static (actual db) model

Data ServicesExposes and takes IQueryable<T> so datasets very easy to work with in a LINQ like way

Routing lets URI act like a Linq query

http://Root/my.svc/Customers/35/FirstName

VS2008 & .NET V3.5 SP 1 Overview

Ajax enhancementsHistory Points

Addresses problem that users lose ability to hit back button

Script combiningTo improve performance allows combining libraries

Other EnhancementsImproved javascript intellisense

Improved web designer performance (bugs/regressions addressed)

11

VS2010: IDE Enhancements

Quick Search

Call Hierarchy

Code GenerationTest-driven development

New WPF text editor

More reliable & modular

VS2010: Web Features

Document Outline extended

HTML Snippets

Jscript Intellisense V2See dynamically created members

File reference hints

XML document comments

Web Deployment

Improved CSS 2.1 Support & Standards Compliance

14

C# v4.0

HistoryV1 – Managed Code big emphasis

V2 – Generics; finished the language

V3 – LINQ

V4 – DynamicCall any method of a dynamic object and the compiler won’t complain

No intellisense possible

Will call during runtime

Lots of power to be explored here

15

C# v4.0

Optional ParametersNamed parameters

Can also skip optional parametersPublic StreamReader OpenTextFile(string sFile, bool bReadOnly = true, int nBufferSize = 1024);

sr = OpenTextFile(“foo.txt”, buffersize:4096);

COM InteroperabilityNo more “ref dummy”!

Will get: doc.SaveAs(“Test.docx”); //Winword SaveAs

Versus: doc.SaveAs(“Test.docx”, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy, ref dummy);

16

C# v4.0

COM Interoperability (cont.)Automatic dynamic mapping so less unnecessary casting

Interop type embedding

No more bringing in PIA; includes in your assembly

Deploy office solutions to SharePoint

Safe Co and Contra-variance

Compiler as a serviceCompiler black box opened up to be used and extended

C# and VB to co-evolve in the future

17

Parallelism

Need to start thinking about parallelismUnderstand goals vs. usage

Measure existing performance. VS2010 has tools to do this

Tuning Performance

Typically we start with sequential programming and add parallelism later

VS2010 has Profiler tool for tuning performance

Identify opportunities for parallelism

18

Parallelism

IDE Tools to make life easier

Parallel ExtensionsFirst class citizen in VS2010 (v3.5 CTP Preview available)

Parallel.For and Parallel.ForEach

Still need to use critical sections around shared resources inside loop

Parallel extended IEnumerable to perform queries much faster

var q = from n in arr.AsParallel() where IsPrime(n) select n;

19

AJAX: Overview of Usage Patterns1. Server-Side ASP.NET

Using server-side controls

2. Server-Side ASP.NET AJAXUsing the UpdatePanel control (wisely!)

3. Client-Side ASP.NET AJAXUsing the Microsoft AJAX Library (services and scripts)

4. Client-Side ASP.NET AJAXUsing client-side templates and controls

5. Client-Side ASP.NET AJAXUsing declarative client-side controls

20

AJAX v4.0

New FeaturesDeclarative Controls

XML is eXtensible!

xmlns:dataview=“javascript:Sys.UI.DataView”

Data Source Control

Command Bubbling

Live BindingsUsed to execute JavaScript in the context of the current data item
