C#: I need to create a memory matching game in C#

Some details the game needs to include are:

-Keep track of the number of guesses made (a guess is a 2 unique card click). This value should be updated after every 2 card click

-Keep track of how long the game has been running from first card clicked until the game is won. This should be updated every 2 card click

-Cards should be randomized so no two games are the same (random selection of characters and random placement of characters).

-The game is over when all 16 matches have been made.
