I m new to c# and facing problem in own custom namespace .

Hi,

    I am new to C#  and I made own custom namespace lets say "namespace1" and referred in another namespace lets say "namespace2". When i run them , error comes like:

"Error 1 Program 'c:\c#_projects\namespace1\namespace1\obj\Debug\namespace1.exe' does not contain a static 'Main' method suitable for an entry point C:\c#_projects\namespace1\namespace1\CSC namespace1" .

 

 

Please rectify it.

 

 

 

Source Codes are given below:

 

1. namespace1 :

 

 

using System;


namespace namepspace1
{
class n1
{
public void Hello()
{
Console.WriteLine("Hello, C# World!");
}
}
} 

 

 

 

 2. namespace2 : 

 

 

 using System;
using namespace1;

namespace namespace2
{
class n2
{
static void Main()
{
n1 cls = new n1();
cls.Hello();
}
}
}
