Framework Multitargeting

.NET Fx 2.0.NET Fx 2.0 Update.NET Fx 2.0 Update.NET Fx 2.0 Update.NET Fx 3.0 Update.NET Fx 3.0 Update.NET Fx 3.5 Whidbey Vista Orcas time Version = Assembly references + compilers No new CLR runtime Framework Multitargeting

 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

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

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

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

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

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

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

Core Language Enhancements

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

Handle Data

Problem: Data != Objects

The LINQ Project Objects XML.NET Language Integrated Query C# 3.0VB 9.0Others… Relational LINQ to Objects LINQ to SQL LINQ to XML LINQ to Entities LINQ to DataSets

LINQ Operators RestrictionWhere ProjectionSelect, SelectMany OrderingOrderBy, ThenBy GroupingGroupBy JoinsJoin, GroupJoin QuantifiersAny, All PartitioningTake, Skip, TakeWhile, SkipWhile SetsDistinct, Union, Intersect, Except ElementsFirst, Last, Single, ElementAt AggregationCount, Sum, Min, Max, Average ConversionToArray, ToList, ToDictionary CastingOfType, Cast

SqlConnection c = new SqlConnection(…); c.Open(); SqlCommand cmd = new c.Name, c.Phone FROM Customers c WHERE c.City ); " 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(); Data Access In APIs Today

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();

LINQ Architecture Objects XMLRelational LINQ enabled data sources LINQ enabled ADO.NET

LINQ Basics  Query Operators can be used against any.NET collection (IEnumerable )  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 sequences

Searching/Sorting an Array string [] cities = { “Auckland”, “Oslo”, “Sydney”, “Seattle”, “Paris”, “Los Angeles” }; IEnumerable places = from city in cities where city.Length > 5 orderby city descending select city; GridView1.DataSource = places; GridView1.DataBind();

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

Projections w/ Anonymous Types List 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();

Projections w/ Anonymous Types

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

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

Code Associations in Model public partial class Product { public int ProductID; public string ProductName; public Nullable SupplierID; public Nullable CategoryID; public Supplier Supplier; public Category Category; } public partial class Supplier { public int SupplierID; public string CompanyName; public EntitySet Products; } public partial class Category { public int CategoryID; public EntitySet Products; }

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

LINQ to XML XElement contacts = new XElement("contacts", from c in customers where c.Country == "USA" select new XElement("contact", new XElement("name", c.CompanyName), new XElement("phone", c.Phone) ) ); Declarative model Element-centric Integrated queries Smaller and faster

ADO.NET vNext  Data as Objects  The Entity Data Model (EDM), which allows developers to model data at a higher level of abstraction  Client-views/mapping engine to map to and from store schemas  Full query support over EDM schemas using Entity SQL and LINQ  Open provider model that allows other stores to plug into the ADO.NET Entity Framework  Data Integration to core languages  Language-Integrated Query (LINQ)  LINQ to Entities: formulate queries using LINQ against your EDM schemas  LINQ to DataSet: the DataSet with full query capabilities  LINQ queries can go against one or more DataTable objects

ADO.NET Entity Framework (1/2)  "Client Views" map existing relational schema to a rich conceptual entity model  Conceptual entity model exposes concepts that make sense to your application  Different apps may have different views of the same data  Application and storage schemas may evolve independently  Exposed as an "Entity Client" ADO.NET Data Provider  Common, familiar ADO.NET Programming pattern Compatible with existing applications/tools  Canonical Entity SQL “eSQL” used to query Conceptual Model  Supports 3rd party ADO.NET Data Providers

ADO.NET Entity Framework (2/2)  Entities presented as CLR Objects  Work with higher level "ObjectContext" Tracks object identity, changes  Query through Entity SQL or LINQ queries  Entity Data Model Designer  Integrated into the Orcas IDE  Create entities from scratch or generate EDM models from an existing database  Easily consume existing EDM models

Sync Services for ADO.NET  Simplifying the Client “Golden Nugget”  Application works against a local data cache and periodically synchronizes with the server  Experience unchanged on lost connectivity  “Want local caching, but can’t spend time getting the basics right”  All the heavy lifting handled by the Framework  “Want to leverage/extend your my ADO.NET knowledge”  “Want to build real world N tier Application”  Sync via services with pluggable proxy/service  Server Data Components can use any ADO.net Provider  Application supports Occasionally Connected Scenarios

Sync Component Architecture Data Forms SyncAgent Data Access Work against local database Sync keeps the local and remote stores in sync Can push changes directly or via services SyncTable SyncAdaptercommands SyncAdapter ServerSyncProvider DBCommand SQL Server Compact Edition 3.5 Transport Service ServiceProxy Client SyncProvider SyncGroup Server DB
