//C# program to demonstrate the 
//CLSCompliant attribute.

using System; 

[assembly:CLSCompliant(true)]   
public class Sample
{ 
    public uint num; 
} 
  
class Program
{ 
    public static void Main(string[] args) 
    { 
        Console.WriteLine("Hello world"); 
    } 
} 

Output:

Compilation succeeded - 1 warning(s)
Hello world

Explanation:

In the above program, we created the two classes Sample and Program. Here, we used the CLSCompliant attribute with Sample class. Here, the declaration of num data member will generate a warning. Because the CLSCompliant attribute is used to generate a warning message when a code element is not CLS compliant.

The Program class contains the Main() method. The Main() method is the entry point for the program. Here, we printed the "Hello world" message on the console screen.
