I was trying to follow the example in article 252152 (Solitaire) and entering the third cs fie I got an error. The code segment was in the module "PlayingCard.cs" where the code was attemping to derive the "Suit" based on the int position of an enumerated type.

----------------
The line is :

int enumval = (int)CardType;

The word "CardType has a red underline.

-----------------
When hovering over it, the error message reads:

enum Sol.CardType
The Card Type.

Error
"Sol.CardType" is a "Type" but is used like a variable.

---------------------

I checked the spelling paying particular attention to upper vs lower case. and the example code I downloaded (and placed in a different folder) has the exact same code. So why does this line show NO error in the example code, BUT in mine has an error? I mean I do see in CardTpye.cs where the enum type of the same name is declared so I understand the error message. I don't understand why it works in your example code?
