Mix08

MIX08-The Recapping the love that was.

mikedopp — Sun, 09 Mar 2008 15:05:06 GMT

This past MIX was my sophomore year. I had the chance to go to MIX07 last year. In fact have a glance at my RSS feed for that. I traveled once again with Joe Levi, courtesy of Lifetime Products.

The great things about MIX was the sessions. I did however enjoy the keynotes as they do always get you fired up for the rest of the conference as well as giving you a chance to see what and where Microsoft is going with the .NET framework as well as ASP.NET.

My feet are still blistered and I still am morning the loss of my Hacked Zune.

However the experience was awesome. I am hoping to be at MIX09 for my Junior year there.

I can’t forget to give a friendly shout out to my new friends in the .NET community. I even made some friends from company’s like:

WeatherBug Tamir Melamed

Godaddy David Koopman

Jinx.com Scott "Brolo" Benner

Yahoo! Joshua Jacobson

CodeSmith Eric Smith

MotionCloud Pureum Kim

Koda Software Tor Langlo

RogerGuess

Geoffrey Emery

Alec Bryte

And More...

Favorite Session:

ASP.NET MVC - Scott Hanselman

Least Favorite:

WPF Development. Not because it was bad but it was the last session and I was exhausted.

Overall it was a great experience.

By the way check out a great Elvis/Johnny Cash impersonator

Thanks again Lifetime and Microsoft.

MIX08- Developing ASP.NET Applications Using the Model View Controller Pattern.

mikedopp — Fri, 07 Mar 2008 06:52:38 GMT

http://www.hanselman.com

scotths@microsoft.com

New web project type for asp.net
More control over your </html>
Testable framework
Not for everyone

Master Cheif GU!

.NET 3.5 MVC web application template.

Options:

Enable testing right out the gate. NVUnit or any Unit.
No testing option

System.Web.MVC System.Web.Extension System.Web.Routing [Namespace]

Controllers Models and Views

Controller is a base class Index and about public class’s {controller/action} Direct relationship.

Flexible Fundamental, Plays well with others, Dry or Simple don’t repeat yourself.

Clean Separation of Concerns

Easy Testing
Red/Green TDD
Highly maintainable applications by default

Extensible and Pluggable

Support replacing any component of the system

Driving Goals:

Enable clean URLS and HTML

-SEO and REST freindly URL structures

Great integration within ASP.NET

MVP vs. MVC

Presenter: Up front presentation

Controller: Component

AJAX with MVC? Cannot Drag the ajax controls to the page.

-AJAX can be used but all code behind.

MVC RTM: When Duke Nukem Forever comes out.

Security: Is it safe? Same as ASP.NET!

Performance/Scalability Only as good as you write it.

MVC what is it?

Browser requests /Products/
Route is determined
Controller is activated
Method on Controller is invoke
Controller does some stuff
Renders View, passing in custom ViewData
URLs are rendered, pointing to other Controllers

Request->HTTP Routing->Route->Route Handler->Http Handler-> Controller-> View Engine-> View-> Response

Clean code!

URL Routing Pretty URIs -Developer adds routes to a global RouteTable -Mapping creates a RouteData -a bag of key/values

Route Testing for URLs Very SEO friendly.

Views

Controllers

Models

Routes

are all Pluggable

ViewEngineBase

View Engine render output

You get WebForms by default

Implement your own.

MVCContrib Brail Nvelocity
NHaml

View Engines can be used to offer new DSLs to make Html easier.

Making Microformats.

<% { %>

code between

<%}%>

Mockable Intrinsics:

HttpContextBase, HttpResponseBase, HttpRequestBase

Extensibility:

IController, IControllerFactory, IRouteHandler,ViewEngineBase

RhinoMocks or TypeMock

Create Tests of the runtime.

For loop on front end?

MIX08-Building Applications and Services with .NET Framework 3.5

mikedopp — Fri, 07 Mar 2008 01:02:26 GMT

Using new features in .NET 3.5 Framework. blogs.msdn.com/justinsmith

What in .NET 3.5 for services:

The New HTTP Programming model:
New support JSON Services
Syndication in .NET 3.5

Service Stack Evolution

-Sockets->HttpListener->ASP.net->ASMX->WCF

WCF

one stop shop for services

Myth:WCF is only for enterprise services

Reality:WCF gets around(enterprise and web)

.NET 3.5 WCF web-centric upgrades:

Make REST a 1st class citizenish
Embrace SOAP-less representations
JSON messaging capabilities
Simple working with POX
RSS & Atom syndication support

Run in partial trust (hosting) cool!

Promote web concepts to top status by simplifying the (mapping URIs to application logic, working with HTTP methods and working with Response codes & HTTP Headers)

Support for SOAP/RPC & REST from one or same application.

.NET 3.5 additions:

System.UriTemplate

Type for modeling URI to app semantics
Bind Data to a template, output to URI
Match a URI to a template, retrieve data

System.UriTemplateMatch

Returned from UriTemplate "match"
Get relative paths

System.UriTemplateTable

Simple URI-to-application mapping -Defaults to query string parameters

Http verbs in WCF Contracts

All HTTP GET POST PUT DELETE
View it vs Do it separation mimics web

Specify Data Format in WCF:

WebOperationContext.Current provides access to incoming request headers

Can also set outgoing response headers

Bindings and ServiceHosts:

WebHttpBinding and WebServiceHost

Use WebServiceHost/Factory in most cases

WebHttpBinding endpoint on a ServiceHost

Add webhttpBehavior to the endpoint

Interpretive dance of solution for DEMO.

Cassini for services. Sounds fun.

How to reverse a string demo. *you need to know this if you want a job at Microsoft.

public string someMethod(string, input)

{

char[] chars = input.ToCharArray();

Array.Reverse(chars);

return new string(chars);

}

Go ahead and cheat. its ok.

0 config setup. Service host holds your config info.

use imperative 'approach"or web.config is by default.

JSON-centric Types:

JsonReaderWriterFactory

-creates XmlDictionaryReader/Writer objects

DataContractJsonSerializer

-Bridges objects & JSON

JSON messaging:

Set requestsFormat/ ResponseFormat

WebHttpBehavior to endpoint

Intergrates with ASP.net AJAX

WebScriptEnablingBehavior to endpoint

Use WebScriptServiceHost/Factory for automatic endpoint creation (0 config)

I have got to get working on this.

MIX08- Introducing SQL Server Data Services (SSDS)

mikedopp — Thu, 06 Mar 2008 23:33:49 GMT

Microsoft Data Platform

Rich data services from SQL Server

Using of course SOAP REST and APP within SQL Server SSDS.

Live contacts has ADO.NET Connections...

SYNC Framework synchronize contacts between endpoints.

pulling or GET from url into xml or web service.

Metadata file with Vcard info.

No invoke needed within browser just service on box?

SQL Server Data Services:

Application Agility
Scales without limits
Business Ready SLA

Scalable or downgradable to 2005 or 2000?

SQL Server Data Services Layers:

SQL Server Data services
SQL Server Data Services Platform
Global Foundation Services

'ACE' concepts:

Authority - Dns Name

Container - Unit of consistency/search. No schema required.

Entity - Property of name/value pairs. Update/change

Syntax:

<Entity>

   <s:container>

      <s:Id />

      <s:version>

       <strprop/>

    </s:container>

</Entity>

Need to find SSDS explorer.

data.sitka.microsoft.com

SSDS syntax is very close to LINQ syntax.

Demo was a Simple REST POST

Service runs on SYNC framework

Entity:

Flexible Entity Model

Smallest unit of measure(unit of update)

Metadata Properties

ID- unique within parent container
Kind-track user type ex:Joblisting, resume, etc.
Version- update timestamp on each operation

Flex Properties

Can change instance type or add additional properties
Support for simple types:decimal, string, bool, etc
All properties are indexed.

When you add a property to an entity automatically searchable.

*Entity properties may differ in type and instance.

*Container stores flexible entities, Unique name within parent.

*Authority holds DNS name, unit or billing and geo-location, analog to namespace.

Web Service API (SOAP/REST)

Both supported, Endpoint secured by SSL

Each authority has single owner

Secured using single owner credetials

Operations

Authority: Create Update and Delete

Container provisioning

Entity storage, update, delete, and query

Query uses simple LINQ-like syntax

Exposes URI for each resource:

Service: https;//data.sitka.microsoft.com/v1CreateAuthority(post)

Authority: https://auth.data.sitka.microsoft.com/v1

FetchAuthority (GET)

QueryContainers(GET) with query

CreateContainers(POST)

Container:

DeleteContainer(DELETE)

Create(POST)

So Sync Framework takes away the middle tier to a web service app. Write your front end with all your <%#Eval("INFO")%> from datasource = to url of sql server. Is that exactly safe?

Beta by invite only!

Live not available until first quarter 2009... So is this just a service from Microsoft or a true add on to your own SQL Server?

Live will be pay per use. Wow this just went another direction. Hate paying for services.

To sign up for beta:

www.microsoft.com/sql/dataservices

http://blogs.msdn.com/ssds

nigel dot ellis at microsoft dot com

This looks like Microsoft’s answer to Amazon S3 or Simple DB Services.

MIX08- Second Day Early Morning

mikedopp — Thu, 06 Mar 2008 22:31:31 GMT

I have a ton of video from the keynote. However it is all grainy and well even Microsoft expressions is have a hard time with it. So I will try to get some better pictures. A couple of great apps that have been discovered:

cetwit- windows mobile twitter application

feedslide - One click application for turning rss feeds into jpegs for zune or ipod.

Images from the Luxor.

Had to add Yesterdays lunch.

Yes I twitter. Maybe too much.

MIX08-Restful Data Services with the ADO.NET Data Services Framework.

mikedopp — Thu, 06 Mar 2008 08:33:52 GMT

I am a huge fan of Pablo Castro(the presenter).

Astoria has become ADO.NET Data Services Framework.

Data in the web:

Ajax applications
Silverlight applications
Online Services
Mashups

Restful Interface for Data:

Just Http
Data as resources, HTTP methods to act on it.
Uniform URL syntax
Every piece of info is addressable
Multiple representation
Use regular HTTP content-type negotiation
Atom, JSON, Plain XML

Book: Restful Web Services

Drill down data using Astoria(http request or get)

Model and Operation Semantics

Underlying data model
Entity Data Model
Entities -> Resources
Associations -> Links

Operation semantics

      Usual mapping of HTTP methods

      Get -> retrieve resource

      Post -> create resource

      Put -> update resource

     Delete -> delete resource

URL Conventions

Addressing entities and sets

Entity-set /Bookmarks

Single entity /Bookmarks(123)

Member access /Bookmarks(123)/Name

Link Traversal /Bookmarks(123)/Tags

Deep access /Bookmarks(123)/Tags/('abc')

Raw value access /Bookmarks(123)/Names/

Key words and syntax:

$value get rid of (goo) xml or data tags

$filter = Color eq Red Get color red by filter Dollar signs so you don’t use names?

$orderby

= or eq

$paging

$top

$skip

$expand (=has to be a link)

Format your data just using a http strings

Data Services

Various data sources
Entity Framework
Linq providers

Model-driven

Structural description in Entity Data Model
Metadata shapes service

Create a linq provider use Astoria to turn it into service and you have http data access.

Set your rules in your class or web.config.

"config.SetEntitySetAccessRule("",EntitySetRights.All);"

Refining and Securing Services

Visibility

Read, Query, and Write options.

Authentication
Interceptors

Execute before HTTP GET/PUT/POST/DELETE

Service Operations

Custom entry points /MyTags?startDate='2002-28-08'

Astoria is:

Ajax integrated

Silverlight supported

Astoria is the future of data mining!

Lower server resource usage

Supports Secure sockets Layer(SSL)

Firewalls

Cons:

No Live

No advanced

No buffer

Streaming Download:

Pros:

Basic and advanced media features

Bandwidth optimization

Enables Live broadcasting

Cons:

Requres management infrastructure

Cant deliver content encoded at a higher bitrate than connection speed.

IIS7 Media Pack

Media delivery on top of IIS7
Bit rate throttling
web server playlist
adds basic streaming
Free www.iis.net

Distribution services

Outsource

Silverlight.live.com
Content Delivery Networks
For Public consumption
Do it yourself server 2008

Using IIS7

Using Windows Media Services 2008
Very popular on internal networks
Push internally to CDN(outside/inside)

"Silverlight is the future of streaming on the web"

WMV ecosystem:

Mature live streaming
Big Ecosystem
intergration into major editing platforms

Why WMV and VC-1?

Greater quality
Better decode performance
up to 2x pixels/second of H.264
Large existing libraries of content

It is just windows media

Most existing files urls work
Media features baked into runtime
no OS codecs
Video codecs
wmv7/8/9 9advanced profile

Mix08- Working with Data and Web Services in Silverlight2.

mikedopp — Thu, 06 Mar 2008 03:09:30 GMT

Applications interact with the outside world. mmm?

Mashups and such. ok

Many types of outside data....

Images
RSS
Business services
Intranet services
Mashup API’s

silverlight1.1 xaml and fun

-no easy way to connect to other services.

What does client code look like?

Custom services.

Recommended uses of services in silverlight

Using silverlight front end connecting to webservice or database directly.

Using C#

void list<product>getproducts (string searchstring)

Create service
Define What does
Add Service reference
Use the service

Silverlight-Enabled WCF Service

ServiceContract
OperationContract
DataContract

Reference the service

var proxy = new ShoppingServiceClient() [service]

Default address chosen if no parameters given
canpass in addresss manually
but what if the service moves?
Config support after beta1

Only uses async methods

migrate from silverlight1.1 on client side

Remove web references
do add service reference
Data format is now SOAP, not JSON

Server-side no need to change!

Using cookie or session data to pass authentication.

silverlight consumes web page authentication.

HttpContext.Current.User = current user

Pull in outside service

Add Service Reference

include:

Services
Soap
Soap internet
SQL Server Data services

WSDL connection... nice!

No cross domain applications!

mysite.com cannot call yoursite.com using the same authentication mysite.com.

you can hack it using the policy files:

silverlight policy file clientaccesspolicy.xml
adobe policy file crossdomain.xml

3rd party authentication using browser based authentication is looked down upon.

Allowed Urls Http and https subject to cross domain rules no ftp or file://URLs

Sockets support for non-HTTP Services:

-originating server only.

Download code:http://code.msdn.microsoft.com/silverlightws

Restrictions:

No Put,Delete
Only get success of failure. No debugging? That’s not so cool.
- -403 and 404 will not be displayed.
Redirects:Work(may be blocked in cross-domain)
Cannot override the browser
Caching turned off
http authentication
read/write cookies.

Access to XML
