Deploying ASP.NET site in IIS

Deploying your web application into  IIS is one of the major tasks for  a developer before moving into UAT or testin. I found the following link useful

It has  a lot of screenshot to help your to easily understand the process. It talk of deploying asp.net site into IIS 7.0 server but also applicable to later versions of IIS servers.

Reflection and Attributes

Attributes describe the behavior of .net objects like class, method, function, interface etc to the runtime.
There predefined attributes and custom attributes that can be defined by user. The custom attributes are used to store the information.

Reflection is a set of classes that one uses to explore the .net objects during the runtime itself.

Working with Generics

Generics in C# help you to create light weight class that can take any type of parameter as input. This sort of helps in maximum code reuse.
I came across an excellent explanation on Generics and its uses on MSDN.

Below is the link :-

Here is a brief tutorial on using generics :-

Isolation Levels in SQL server 2008 onwards

There are 5 isolation levels supported in SQL server 2008:-

1. Read Uncommitted
2. Read Committed 
3. Repeatable Read
4. Serializable
5. Snapshot  

Isolation levels protect data during sql server transaction against dirty reads.

Found an excellent and simple post on this:-
