What is the advantage of static class over class ?

.1  When we have a normal class and its methods being used very frequently in a given app, then it would speed up things if we made this class a static class with static methods. This is because there is always a cost incurred in terms of resource usage ( CPU, memory, time) EVERY TIME a normal class is instantiated, whereas for static class its only a ONE-TIME cost when static constructor is FIRST called. 

2. The main advantage of Static Classes come when there is a need to use WebMethod or a webservice, so that the application can call the static method without creating an object.

Claims Class For security in .NET4.5 with C#

What is Claim ? A claim in the world of authentication and authorization can be defined as a statement about an entity, typically a user.

This external trusted entity is called an  Issuer . The KEY in the key-value pairs is called a  Typ...

Design Patterns

                                                      Design pattern 1. Factory Design Pattern  In Factory pattern, we create object without exposing the creation logic to the client and refer to newly created object using a common interface. Step 1 Create an interface IShape.cs public interface I Shape { void draw (); } Step 2 Create concrete classes implementing the same interface. Rectangle.cs public class Rectangle : I Shape { @Override public void draw () { C onsole.WriteLine ( "Inside Rectangle::draw() method." ); } } Square.cs public class Square : I Shape { @Override public void draw () { C onsole.WriteLine ( "Inside Square::draw() method." ); } } Circle.cs public class Circle : I Shape { @Override public void draw () ...
