I have a C# Visual Studio project that implements a connect four game that I need help with. The program should correspond with the given GUI:

For this assignment, you are to build a program that plays the game, Connect Four. While expert level play is not required, it should provide a challenge for those who are only casual players of the game. User Requirements Connect Four is a two-player game played on a vertical board. The board is a grid af six rows and seven columns. Players take turns dropping their game pieces into one of the columns. Because the columns are vertical, each piece drops to the lowest unoccupied cell in that column. Each player's goal is to get four of his or her pieces in a straight line of adjacenct cells, either horizontally, vertically, or diagonally. If the board is filled before either player wins, the game is a draw. More information, including an animation of the game, can be found on the game's Wikipedia pagee The user is a company that wants to market a version of the game. This implementation needs to support user play against the program. It must allow the user the option of having either the first or second play. It also needs to support seven levels of play difficulty. Because this is a first release of the game, expert play is not required, but each successive level should play a stronger game. At the end of the game, it must report the winner, or that the game was drawn. It only needs to support playing a single game (the program can be restarted for a rematch), but it needs to leave the final board visible until the user exits the progran For this assignment, you are to build a program that plays the game, Connect Four.
