Do you avoid Empty code blocks?

Empty Visual C# .NET methods consume program resources unnecessarily. Put a comment in code block if its stub for future application. Don’t add empty C# methods to your code. If you are adding one as a placeholder for future development, add a comment with a TODO.

Also, to avoid unnecessary resource consumption, you should keep the entire method commented until it has been implemented.

If the class implements an inherited interface method, ensure the method throws NotImplementedException.

public class Example
 {
       public double salary()
       { 
   
       }
 }

public class Sample
 {
       public double salary()
       {
               return 2500.00;
        }
 }

public interface IDemo
 {
       void DoSomethingUseful();
       void SomethingThatCanBeIgnored();
 }
public class Demo : IDemo
 {
       public void DoSomethingUseful()
       {
              // no audit issues
             Console.WriteLine("Useful");
       }
       // audit issues 
      public void SomethingThatCanBeIgnored()
      { 
      } 
 }

public interface IDemo
 {
       void DoSomethingUseful();
       void SomethingThatCanBeIgnored();
 }
public class Demo : IDemo
 {
       public void DoSomethingUseful()
       {
              // no audit issues
              Console.WriteLine("Useful");
       }
       // No audit issues 
       public void SomethingThatCanBeIgnored() 
       {
              // stub for IDemo interface
       } 
 }
