Streaming Photo Data Service Sample

arunganesh@gmail.com (G. Gnana Arun Ganesh) — Mon, 24 Jan 2011 08:47:00 +0000

Through Open Data Protocol (OData) one can expose data feeds of binary large object (BLOB) data, such as photos, videos, and documents. This sample demonstrate how to use the IDataServiceStreamProvider interface in WCF Data Services to implement an OData service that uses a streaming provider to store and retrieve image files, along with information about each photo.

WCF Data Services

arunganesh@gmail.com (G. Gnana Arun Ganesh) — Mon, 24 Jan 2011 04:45:00 +0000

WCF Data Services

The Open Data Protocol, referred to as OData, is a new data-sharing standard that breaks down silos and fosters an interoperative ecosystem for data consumers (clients) and producers (services) that is far more powerful than currently possible.

WCF Bindings

arunganesh@gmail.com (G. Gnana Arun Ganesh) — Tue, 26 Jan 2010 14:34:00 +0000

Binding: How do I communicate to the service?

· Binding provides information on how a service can be accessed including transport method (HTTP / HTTPS / TCP / Named pipe / MSMQ), encoding format (Text / Binary /MTOM), security mechanism, reliability requirement etc...

- A service to be accessible, at least it should be associate with either one or more bindings.

- A contract can support many bindings and a binding can support many contracts.
· Out of the box, Indigo support following bindings which covers most of the common scenarios.
- Developers can create their own custom binding based on their requirement with the mix of functionality.

Bindings ship with WCF

basicHttpBinding - Suitable for communicating with WS-Basic Profile conformant Web services
wsHttpBinding - Secure and interoperable binding that is suitable for nonduplex service contracts.
wsDualHttpBinding - Secure and interoperable binding that is suitable for duplex service contracts.
wsFederationHttpBinding - Secure and interoperable binding that supports the WS-Federation protocol
netTcpBinding - Secure and optimized binding suitable for cross-machine communication between WCF applications.
netNamedPipeBinding - Secure, reliable, optimized binding that is suitable for on-machine communication between WCF applications.
netMsmqBinding - A queued binding that is suitable for cross-machine communication between WCF applications.
netPeerTcpBinding - A binding that enables secure, multimachine communication.
msmqIntegrationBinding - A binding that is suitable for cross-machine communication between a WCF application and existing Message Queuing applications.
webhttpbinding is a new Web Friendly Binding which is used for services that are exposed through HTTP requests (Not through SOAP).

Let's see a quick example:

In the above configuration, you can see we have multiple endpoints which expose the contract: MyExample.IBook.

Endpoint 1 : Address is Empty, which means which will take the base address. Binding is wsHttpBinding.
End Point 2: Address is having "/basic" which implies the address is: http://localhost:8000/example/service/basic. Binding is basicHttpBinding.
Endpoint 3: NamedPipe Address and binding.
Endpoint 4: TCPIP Address and related binding.

The above simple configuration is enough to expose your service different way.

WCF provides key characteristics like Transport Neutral (Http, TCP, MSMQ and Named Pipes), various security features, multiple messaging patterns (simplex, duplex and request reply), encodings (text, binary or MTOM), network topologies, and hosting models (Windows, Windows NT Service, Console and IIS).

The above example shows you the that how WCF is one single programming model and runtime which unifies of existing .NET Framework communication technologies like ASMX, Remoting, Enterprise Services, WSE, MSMQ etc...

RESTful Services

arunganesh@gmail.com (G. Gnana Arun Ganesh) — Tue, 26 Jan 2010 11:51:00 +0000

What is REST?
REST defines an architectural style for building services in the “Web” way. It is one of the Buzz word, all together a different thought process!
REST is not tied to any particular technology or platform – it’s just another way to design things to work like the Web. Again this is not something new. REST concept exists for a long time but not utilized to its full power.

Definition:
"Representational state transfer (REST) is a style of software architecture for distributed hypermedia systems such as the World Wide Web. The term Representational State Transfer (REST) was introduced and defined in 2000 by Roy Fielding^[1][2] in his doctoral dissertation. Fielding is one of the principal authors of the Hypertext Transfer Protocol (HTTP) specification versions 1.0 and 1.1." - From wikipedia.org

Why REST Popular?

Is Web Popular?! ;) Web - WWW, which is omnipresent everywhere now. Almost every one knows about Web. RESTful architecture simply follows the tenets of the web which provides the same reach to people.
I will give you a specific example - Just think of accessing a Service as below:

You can access whatever the book detail of any author you want through HTTP GET itself! No Soap Messages, Proxy etc.

amazon.com/authors/{author}/{book}
Ex: amazon.com/authors/ArunGanesh/VS2010

amazon.com/authors/{author}?book={book}
Ex: amazon.com/authors/ArunGanesh?book=VS2010

Key Items to remember:

1. In Web, every resource being referred by a unique identifier, also known as a universal resource identifier (URI). URL+URN = URI

URI / Segment of a URI map to Application Logic. In the above example you can see that the segment of the URL itself being mapped to an application logic.

2. Utilize HTTP Verbs - HTTP GET, POST, PUT, DELETE etc.

3. Utilize HTTP Headers for representing what content type is required and services is returning. For instance, you can represent things like: languages, authentication, authorization, accepted encoding, char set, content type, length etc...

WebHttpBinding Class

arunganesh@gmail.com (G. Gnana Arun Ganesh) — Tue, 26 Jan 2010 02:31:00 +0000

Check this out, if you are new to word - Binding: WCF Fundamentals - One should Know!

WebHttpBinding is a new Web Friendly Binding which is used for services that are exposed through HTTP requests (Not through SOAP).

The WCF Web Programming Model allows developers to expose services through HTTP requests instead of SOAP-based messaging.

Key Items:
1. Binding to build RESTful Servcices
2. HTTP - No to SOAP
3. HTTP and HTTPS Transport.

Support Several Formats like: XML, JSON (Javascript Object Notations) and Binary Streams

New WCF Feature Areas in .NET 4

arunganesh@gmail.com (G. Gnana Arun Ganesh) — Sun, 24 Jan 2010 17:55:00 +0000

1. Simplified Configuration - In each .NET release you can see some rich developer experience and better tool support. With .NET 4.0, support for default endpoint, behavior and bindings. If you didn't metnion anything about configuration settings for a particular service, the WCF runtime automatically configures your service with some standard endpoints and default binding/behavior configurations. Hence for beginers, they can make a WCF service up and running with minimal code!

2. Discovery - Support for WS-Discover protocol which support for both ad-hoc and managed service discovery behaviors.

3. Routing Service - New Routing Service call using which one can implement the required routing features in their services with out writing any custom code.

4. Few REST releated enhanchments.

5. Now Support for implementing declarative long-running workflow services

WCF Service Configuration Editor

arunganesh@gmail.com (G. Gnana Arun Ganesh) — Fri, 30 Jan 2009 18:03:00 +0000

Do you really know there is a WCF configuration editor tool with the entire feature that you are looking for including diagnostics?

Go to this path:

C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin

You can see a tool name - SvcConfigEditor.exe

With this tool, you can manage almost all configuration settings (Both client and Service) including WCF bindings, behaviors, services, and diagnostics without having to directly edit XML files. Isn’t it cool?! Try it.
