New User Needs Help with Console Application

Question

I'm a front end developer who wanted to learn C#.  I'm taking this class and we were presented with a project and I'm having a major disconnect and I am hoping that some kind soul will help me out.  This is very basic and I am so frustrated that I don't understand how to set this up.  I need to create a console application where you can make a bet, then play coin toss or roulette.  I figured I should make each piece seperate and then put them together.  I made the Coin Toss first and then the menu and now I don't know how to call the coin toss app from the menu!!!  Please help me.

I actually was on the right track with coin toss:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace PlayCoinToss

{

    class Program

    {

        static void Main(string[] args)

        {

            string user;

            int user1; // User 1 is the input--what I'm selecting 

            Random numberGenerator = new Random();

            bool playAgain = true;

            string userChoice;

            string houseChoice;

            int house;

            string outcome;

            //Below I'm changing what the console looks like:

            // set background to white

            Console.BackgroundColor = ConsoleColor.White;

            // set foreground to blue

            Console.ForegroundColor = ConsoleColor.Red;

            // clear the screen

            Console.Clear();

            //greeting players

            Console.WriteLine("The user is betting against the house");

            

            while (playAgain == true)

            {

                Console.Write("Please Make Your Selection (1 = Heads and 2 = Tails): ");

                user = Console.ReadLine();

                house = numberGenerator.Next(1, 3);

                while (!int.TryParse(user, out user1) || user1 <= 0 || user1 >= 3) //this is the houses selection.  I'm going to be betting against the house

                {

                    Console.Write("Please Make Your Selection (1 = Heads and 2 = Tails): ");

                    user = Console.ReadLine();

                }

                //below are the rules for me the player

                if (user1 == 1)

                {

                    userChoice = "Heads";

                }

                else

                {

                    userChoice = "Tails";

                }

                //below are the rules for me the house --or whatever I'm playing against

                if (house == 1)

                {

                    houseChoice = "Heads";

                }

                else

                {

                    houseChoice = "Tails";

                }

                //Below I have to figure out who wins and who loses instances of this game

                if (house == user1)

                {

                    outcome = "lose"; //if there is a tie then no money is won or lost

                }

               //need to put how I lose here

                else

                {

                    outcome = "win";

                }

                //Below I have to figure out how to print results and if they want to play again

                Console.Write("You chose " );

                Console.Write(userChoice);

                Console.Write(", the house chose ");

                Console.Write(houseChoice);

                Console.Write("You ");

                Console.Write(outcome);

                Console.WriteLine("Do you want to play again? (yes/exit)");

                user = Console.ReadLine();

                while (user != "YES" && user != "yes" && user != "EXIT" && user != "exit") //They can input all caps or all lowercase since I wrote it this way 

                {

                    Console.WriteLine("Error Please enter yes or exit");

                    user = Console.ReadLine();

                }

                if (user == "YES" || user == "yes")

                {

                    playAgain = true;

                }

                else

                {

                    playAgain = false; //the only important thing is that they enter yes

                }

            }

        }

    }

}

I kind of started getting confused reading the requirements after that.  Then I repurposed a menu here

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

namespace ConsoleApplication1

{

 class Program

 {

 static void Main(string[] args)

    {

       

        const int maxMenuItems = 4

            ;

           int selector = 0;

           bool good = false;

            while (selector != maxMenuItems)

           {

              Console.Clear(); 

               DrawTitle();

               DrawMenu(maxMenuItems);

               good = int.TryParse(Console.ReadLine(), out selector);

                if (good)

              {

                   switch (selector)

                   {

                        case 1:

                            Console.WriteLine("// code for case 1 here");

                           break;

                        case 2:

                            Console.WriteLine("// code for case 2 here");

                          break;

                        case 3:

                         Console.WriteLine("// code for case 3 here");

                          break;

                        case 4:

                         Console.WriteLine("Exit");

                         break;

                    

                      default:

                         if (selector != maxMenuItems)

                            {

                                ErrorMessage();

                            }

                            break;

                   }

               }

                else

                {

                   ErrorMessage();

              }

               Console.ReadKey();

            }

        }

       private static void ErrorMessage()

        {

            Console.WriteLine("Typing error, press key to continue.");

       }

        private static void DrawStarLine()

       {

           Console.WriteLine("************************");

        }

        private static void DrawTitle()

       {

            DrawStarLine();

            Console.WriteLine("+++   Lets Play a Game   +++");

            DrawStarLine();

        }

       private static void DrawMenu(int maxitems)

       {

            DrawStarLine();

            Console.WriteLine(" 1. Add Funds");

            Console.WriteLine(" 2. Coin toss");

            Console.WriteLine(" 3. Roulette");

            Console.WriteLine(" 4. Exit program");

            DrawStarLine();

            Console.WriteLine("Make your choice: type 1, 2, 3, 4", maxitems);

            DrawStarLine();

        }

 }

}

  

and now I have managed to totally confuse myself and I'm lost.  Please please help
