I´m new at programming with c#.
I have a problem generating a class Diagram?
I had made a console application and I cant generate a Class Diagram.
I´ve heard that I go to Solution Explorer and right-click on the project and then select View Class Diagram menu item.
I cant select "View Class Diagram menu item" anywhere?
Can someone help me?
This is the console application:

public abstract class MyBase
{
}
internal class MyClass : MyBase
{
}
public interface IMyBaseInterface
{
}
internal interface IMyBaseInterface2
{
}
internal interface IMyInterface : IMyBaseInterface, IMyBaseInterface2
{
}
internal Sealed class MyComplexClass : MyClas, IMyInterface

class program

static void Main(string[] args)

MyComplexClass myObj = new MyComplexClass();
Console.Writeline(myObj.ToString()):
Console.Readkey();

Class diagram is a static diagram and it is used to model static view of a system. The static view describes the vocabulary of the system.

Class diagram is also considered as the foundation for component and deployment diagrams. Class diagrams are not only used to visualize the static view of the system but they are also used to construct the executable code for forward and reverse engineering of any system.

Generally UML diagrams are not directly mapped with any object oriented programming languages but the class diagram is an exception.

Class diagram clearly shows the mapping with object oriented languages like Java, C++ etc. So from practical experience class diagram is generally used for construction purpose.

So in a brief, class diagrams are used for:
Describing the static view of the system.
Showing the collaboration among the elements of the static view.
Describing the functionalities performed by the system.
Construction of software applications using object oriented languages.
