4 Tenets of Service Orientation

Hi Folks,

This post is to show and describe the 4 tenets of SOA and how is it implemented in WCF Technology in a way,how can WCF to avoid the wellknown pitfalls of using current technologies such as (WSE):

1) Boundaries are explicit :
Applications is communicating to each other by sending and receiving messages to each other.

2) Services are autonomous: you can't control any service out of your organization boundaries.
Your solution should be loosly coupled ,so it can tolerate these changes and continue running if one or more services are un available.

3) Services share schema,contracts not classes or types: simply each service publish the schema of the data which will be exchanged between the service and clients and how can be binded to the clients,these information is used by clients to consume the published services.

4)Compatability is based on policy:Schemas and contracts exposed by the service is define the "Shape" of the service.

if you familiar with WS Enhancements,it has its specification on WS-Security,WS-Interoperability....etc which has been encapsulted into the WCF unified platform.

Deploy WSS 3.0 Web Part

Hi Folks,

This post i will explain how can you dpeloy a wss 3.0 webpart to your shareporint server.

the steps as follows:

1) on your class library,open project properties.
2) select signing tab.
3) check sign assembly check box and select new,and give your snk file a proper name , Close and save.

You will notice that a new snk file has been added to your solution which is used to sign your assembly and give it a strong name.

4) Dont forget to build the dll to be signed with the created strong file name.
5) add your strong name assemly to the GAC using VS command line

GacUtil -i MyAssembly.dll

You can check that the file assemly has been imported to GAC y navigating to :

you will find your dll,this means that your string name dll has been imported successfully to GAC (Global Assembly Cache)

6) Right click on your srong name assembly and select properties,and copy the public token.

7) Create a manafiset file in your project "Manifest.xml"

8) Paste the public token you have saved to the PublickKeyToken attribute under safeControls element in Manifest.xml file.

9) Manifest.xml file should be Content file on the build action property on VS.

on the above steps,your web part is ready to be packaged up to the shareporint server,to create the cab file of this webpart do the following:

10) add a new project, Cab Project.
11) add the primary output / content files to the Cab Project.
12) Build the CaB Project.
13) after building the CAB Project,Rename it to wsp (SharePoint solution file).
14) Take this file (wsp) and insert it using SBS admin tools :
stsadmin -c addsolution -filename MyWebPartCab.wsp

15) On Solution Management on SharePoint Central administration site, you will see the imported solution file which oyu have did on the previous step.

16) Select the solution and click on Deploy Button.

Now you have finished deploying your webpart and you can add it to any web application in your WSS Sites.

Add our webpart to your site on any webpart page,if you didnt find it,add it by clicking on new button on the web parts gallery list.

DataContract Vs. Service Contract

Hi All,
In WCF,Some new terminolgies are come up for .Net Developers,but not for COM,DCOM developers,Since the developers who are familiar with developing Dist. Application used to divide their code to interface and implementations.

The same concept is exist on WCF Tech.,Since the devleopers should divide his servce to :
1- Data 2- Operations.

**Data represented by creating DataContract which expose the data which will be transefered /consumend from the serive to its clients.

**Operations which is the functions provided by this service.

To write an operation on WCF,you have to write it as an interface,This interface contains the "Signature" of the methods tagged by ServiceContract attribute,and all methods signature will be impelemtned on this interface tagged with OperationContract attribute.

and to implement these serivce contract you have to create a class which implement the interface and the actual implementation will be on that class.

Code Below show How to create a Service Contract:

Public Interface IEmpOperations
Decimal Get EmpSal(int EmpId);


Class MyEmp: IEmpOperations
Decimal Get EmpSal()
// Implementation of this method.

Hope now you can differentiate between Data Contract,Service Contract and OperationContract.

DataContract attribute in WCF

Hi Folks,
This is the First post of WCF in my blog,i was little busy with Team System Blogging :),anyway,let's assure one of the first important aspects of WCF programming which is "Contract First" Approach,This approach let the developer or Architect to design his service before starting developing it.
First thing you will do when you create a WCF is creating the Data Contract,which is the Contract that specifies the data will be exchanged between the service and it clients,suppose we need to create a WCF serice which expose Employee Data,The Data Contract will be as follows:

namespace Emp

Class Employee
int EmpId;

string EmpName;

string DeptName;

DataMember attribute you have to put it on each data member in the class in case you want to serialize and deserialize this member which is used on passing or retireving data from this data contract.

DataContract Attribute can be applied on :
1) Classes.
2) Enumerations.
3) Structures.

Hope This helps.
