Hi Folks,
when you create a host for your service,this host manage the context of the service and its states,for this reason,you have to take care how can you configure your host to keep your service under control without any issues regarding the security or performance.
One point regarding the Service performance which is the Service Context:did u ask your self if 1000 Clients call your service ? how manay instances will be created from your service ?
To answer this question,you have to know which mode are your setting your service to work with.
1) Per Session Mode :
How to Implement : Mark your service class with this attribute
C# : [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
Answer : 1000 sessions will be created.
2) Per Call Mode :
How to Implement : Mark your service class with this attribute
C# : [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)]
Answer : Per call the host will create an instance for your service.
This mode give better performance incase the client still opened and not active rather than the prev. mode.
3) Single Mode :
How to Implement : Mark your service class with this attribute
C# : [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
Answer : 1 instance and all clients can share data between them.
Hope this helps.

Breaking and Non-Breaking change on WCF service
Hi Folks,
In this post i want to mention and differentiate between 2 types of changes on any WCF service.
when you are developing a wcf servive,the changes might occur,and before any change you have to test and examine does this change will affect the service clients ?
The changes you have done on a WCF Service,it will affect the client anyway,but the type of the change it might break the client which yield to the client will not work OR it might yield to the client can continues working in a healthy way.
NON Breaking Changes:
Implicit or Explict security checks,change on the logic of the function,add extra binding configuration...etc
Breaking Changes:
Change Method paramaters , Add new paramaeters,change return types,delete methods.
Any Change which will break the client,you have to inform the client owner with the change you have done,to keep the client working.
Hope this helps.

Mid function in VB.net for C# Guys
Hi C# Devs,
I want to convert one of the vb.net code functions to a c# solution for some requirments ,i found on the code the usage of Mid function as one of the important functions on the string manipulation for vb.net developers; as a C# guy,i need an equivelant to it,simply replace the mid function with the following :
VB.Net :
str2= Mid(str1, 1, Len(str1) - 1)
C# :
str2=str1.substring(1);
substring function is the equivelant to Left,Right,Mid functions for VB.Net developers.
VIVA C#.................. :)

Recover SQL 2005 DB passwords
Hi Folks,
I got an urgent request of one of my friends asking for a solution to recover SQL 2005 DB passwords,the situation was as follows:
He took a backup of SQL 2005 DB and set the password option on SQL 2005,and when he tried to restore the DB,SQL 2005 request the password which he forgot it.
My First question was: did he protect the bak file from SQL 2005 or not ? after i got that he protect the DB from SQL 2005,i started to search for third party solution to fix this problem since this DB contains very sensitive information.
I found a third party to recover the SQL 2005 user accounts passwords ,try it now :
http://www.safe-install.com/programs/sql-password.html
The security hole which i discovered that this program can't recover the SQL server passwords if the SQL Engine was configured to use only Windows Authentication Mode; and this is considered as an important security point when we use MS Products with Windows Authentication mode ONLY.
From this post,you have to take care of your SQL installation which mode is an appropriate to your organization.
Hope this helps.
In case you put the password on the bak file,then no way to do any kind of restore to this DB;see more on this article : http://mssqltips.com/tip.asp?tip=1108

Protecting your WCF Service
Hi Folks,
.Net Framework built a robust framework for building distributed application by providing different security means to protect your WCF Service.
you can protect your WCF Service by 3 different ways which is most requested for all different kind of applications :
1) Windows Role Token group based on Active Directory Group.
2) SQL Role Provider: user roles stroed in a DB.
3) Authorization Role Provider : using MS Authorization manager tool.
** This tool let you store the roles in the AD or XML file.
Happy .netting.

.Net 3.0 & .Net 2.0 Design Tips
On the above figure it shows the following:
1) New Technologies coming with .net 3.0 Framework (CF,WF,PF,CardSpace).
2) The Base of .Net Framework 3.0 working on the .Net Framework 2.0,this means any application on 2.0 will not have any interoperability issues or problem to work on .net 3.0 unlike the shift between .net 1.0 to 2.0.
3) Move from Web services to WCF :
-System.ServiceModel is the namespace which provides the whole funcaitonality of WCF.
-Implementing the interface and the implementaiton clsses to implement a WCF service.
(Service Contract,Operation Contract,DataContract)
- Binding information on the web.config,Transport protocol,Endpoints information.
- using svcUtil tool to create proxy classes and clients to your service.
-Integration with COM+,WS,MSMQ,.Net Remoting....etc with WCF

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 :
C:\Windows\assembly
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.
Hope this helps and descriptive.
