Announcement: SocialShare Starter Kit (v1.0) is Released
SocialShare Starterkit v1.0 Relaesed. SocialShare Starter Kit is a kick start application that illustrate a wide range of features that needed to build a social site. And includes features like Status sharing,Blogs,Forums & more. Any one need a lightweight quick solution for his social portal,SocialShare Starter Kit is the savior.SocialShare Starter Kit uses T-4 templates to build logical layers (i.e. DAL/BLL) .

Software Architecture Cheat Blog 1: Design Principles
This blog series will gather summary of all the software architecture design principles under one roof. Intention is to keep in touch with these principles.
First one is called “SOLID”, which is combination of five basic designing principles,
Single Responsibility Principle
Example: http://blog.sanaulla.info/2011/11/16/solid-single-responsibility-principle/
There should never be more than one reason for class to change.
Open – Closed Principle
Example: http://blog.sanaulla.info/2011/11/19/solid-open-closed-principle/
Software Entities (Classes, Modules, Functions, etc.) should be open for extension but closed for modifications.
Liscov Substitution Principle
Example: http://lassala.net/2010/11/04/a-good-example-of-liskov-substitution-principle/
Functions that use pointers or references to base classes must be able to use objects of derived classes without knowing it.
Interface Segregation Principle
Clients should not be forced to depend upon interfaces that they don’t use.
Dependency Inversion Principle
A. High level modules should not depend on low level module. Both should depend on abstraction. Both should depend on Abstraction.
B. Abstraction should not depend on details. Details should depend on Abstraction.
Other important principles are
DRY (Don’t Repeat Yourself)
Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.
Aimed at reducing repetition of information of all kinds, especially useful in multi-tier architectures.
YAGNI – You ain’t gonna need it
Always implement things when you actually need them, never when you just foresee that you need them.
KISS – Keep it simple, Stupid!
Most systems work best if they are kept simple rather than made complex, therefore simplicity should be a key goal in design and unnecessary complexity should be avoided.
Seven Principles Of Software Development
- The Reason It All Exists
- KISS (Keep It Simple, Stupid!)
- Maintain the Vision
- What You Produce, Others Will Consume
- Be Open to the Future
- Plan Ahead for Reuse
- Think

Mark a class or method as deprecated in c#
Background
The attribute Obsolete is used to mark types and members of types that should no longer be used. the Obsolete attribute is found in the System namespace; which means you can specify the type as Obsolete or ObsoleteAttribute—the suffix “Attribute” is automatically added at compile-time. A class or function can be made deprecated in c# by using obsolete attribute.For class/function use this attribute at top of the class/function. You can call attribute constructor by two ways,
[System.Obsolete("WARNING_MESSAGE")]
[System.Obsolete("WARNING_MESSAGE",[show compiler error true|false])]
Below is the example that shows usage of both constructor,
[Obsolete("Method1 is deprecated, please use Method2 instead.")]
public string Method1()
{
//function body
}
Upon calling this function compiler wont produces warning or error.
[System.Obsolete("Class1 is deprecated, use class2"),true]
class Class1
{
public void Method() { //function body }
}
Upon calling instantiating this class, compiler wont produces warning or error.
Places I want to see in my lifetime
I often wonder how amazing the world we live in.There is so many things to do, so many things to see, but its a shame that life is too short. As an occasional traveler I also want explore the world to its end, but it could only possible in a life time until unless if I suddenly became a jumper!! . So recently an idea came up to my mind that I should list all the places that I die to see in my life time (professional obligation need specification before start working). So this is the list of my destination
First place I want to go is Darjeeling @india. I heard so many awesome stuffs about darjeeling that I am absolutely fascinated to go there. Also I like to see Ghoom rail station which was declared a World Heritage Site by UNESCO.
Second place I want to go is maldives. I am absolutely fantasized to see the beaches and one particular thing I want to do is scuba diving and according to me the finest place is Manta point at Maldives. The best time of year to see the mantas is between June and November.
Next stop is Pangong Tso @India, china border. First I came to know about this place at movie called three idiots, I was absolutely stunned to see the beauty of that lake. This spectacular lakeside is open during the tourist season, from May to September, but can’t reach there at winter. why ??? because that time this place is cut off from world due to snow.
My next destination should be Mount Bromo @Indonesia.This area consists of two main volcanic peaks, Mount Bromo and the continually active Mount Semeru!! (kidding me?? I am definatly going).
My fourth destination is Abu-Simbel Temples @Egypt. The most remarkable feature of the temple of Abu-Simbel is that the construction is oriented in a way that twice a year, the morning sun rays shine through the length of the inner temple cave and illuminate the statues of the four gods seated at the end of the cave.
My fifth destination is Machu Picchu @Peru, it is the most familiar icon of the Inca civilization. Specially the intihuatana is believed to have been designed as an astronomic clock or calendar by the Incas.
Fixing database is in use error while restore database from backup
Background
When performing a full restore over an existing database, SQL Backup sometime report that the database cannot be restored because it is currently in use, like shown below
This error shows not only during restore backup, also for drop database or alter database as well.
Workaround
In this situation database administrator needs to disconnect all the connected users from a SQL Server Database to get exclusive access of the Database.In the situation where a full restore is blocked because users are currently connected to the database, the best solution to this problem is to take the database offline prior to running the restore, as this is the easiest way to kill all connections to the database.
Before restore attempt
Database administrator can execute the below mentioned TSQL command to get a Single User access to a database. SINGLE_USER WITH ROLLBACK IMMEDIATE command is used only one user can connect to the database at a time.
use master
alter database DB_NAME set offline with rollback immediate;
After restore
Database administrator can execute the below mentioned TSQL command to give Multiple User access to a database. MULTI_USER command is used any number of users who have rights to connect to the database will be able to connect to the database.
use master
alter database DB_NAME set online with rollback immediate;
So now all authenticated database user can connect to the database again.
IIS deployment error There is a duplicate scriptResourceHandler section defined
Background
Few days back I was attempting to deploy a .net 3.5 website on the default app pool in IIS7 having the framework section set to 4.0, I get the following error,
There is a duplicate 'system.web.extensions/scripting/scriptResourceHandler' section defined.
Solution
The problem occurs because when you use framework 4.0 the machine config already has some of the section defined that were used in previous asp.net versions. So replace the sectionGroup of your existing web.config with the below configs
<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
<sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
<section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication"/>
<sectionGroup name="webServices" type="System.Web.Configuration.ScriptingWebServicesSectionGroup, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
<section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="Everywhere"/>
<section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication"/>
<section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication"/>
<section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" allowDefinition="MachineToApplication"/>
</sectionGroup>
</sectionGroup>
</sectionGroup>
Another work around is to rebuild website/web application using framework 4, and the problem went away.
