title: Error Message "CS5001 Program does not contain a static 'Main' method suitable for an entry point", have multiple classes
body: <p>So here's the deal, I have 2 classes at the moment (planning on adding multiple), and I get this error when i'm trying to call functions from both classes. Same namespace. I double-checked and look at my properties tab to see that it's set to compile.</p>
  
  <pre><code>using System;
  
  namespace Game
  {
  public class SecondSet
  {
  
      public void SituationSecondOne()
      {
          Console.WriteLine(" ");
          Console.WriteLine("Choices:");
          Console.WriteLine("1: First");
          Console.WriteLine("2: Second");
          Console.WriteLine(" ");
  
          int ChoiceOne = Convert.ToInt32(Console.ReadLine());
  
          switch (ChoiceOne)
          {
              case (1):
                  Console.WriteLine("TEST2");
                  break;
              case (2):
                  Console.WriteLine("TEST2");
                  break;
              case (1337):
                  Console.WriteLine(" ");
                  Console.WriteLine("Thank you for playing");
                  Console.ReadLine();
                  Environment.Exit(1);
                  break;
              default:
                  Console.WriteLine(" ");
                  Console.WriteLine("Now, let's try that again ... (¬_¬)");
                  SituationSecondOne();
                  break;
          }
      }
   }
  }
  </code></pre>
  
  <p>Now, when I call the function from the second to the first, I get no error.  What type of Main() method do I need for this? (I also tried to add the original <em>public void Main(string[] args)</em>, once added, I can no longer add <em>public</em> to the function I want to call to the first class)</p>
  
  <p>NOTE: I added this to the first class</p>
  
  <pre><code>SecondSet s2 = new SecondSet();
  </code></pre>
  
  <p>And it works fine as the code is posted above, but I get the compile error mentioned. valve pls fix <em>:/</em></p>
