Cards Game Library

A library for creating a cards games with Silverlight, with two sample Solitaire games.



This is a C# class library for card games; it’s very useful for anyone who is thinking of developing a cards game especially with Silverlight, though it could be used with other .NET technologies as well. It’s also useful as a complete example for anyone who wants to learn Silverlight.

I’ve built two games (Solitaire and Spider Solitaire) using this library, and you can see from the source code that the code written in the individual game projects is minimal and only represent the game rules.

You can see the games on action in my blog:

The actual Silverlight applications are hosted on, which is a great free service from Microsoft.


The solution contains the following projects:

  • Cards.Data

    This is a library for card games, only contains card data and logic, and doesn’t contain anything that is specific to Silverlight.

    Contains the following classes:

    • Game: a class that represents the card game, which contains decks and cards. From this class, you can traverse all the other data classes.
    • Deck: a stack of cards that could be initialized and used as the full cards deck (52 cards) and drawn from it to other decks like player hands or ground stacks.
    • Card: the actual card object.
  • Cards.Silverlight

    This is a library that has Silverlight controls that represent each of the above classes. Each control has a pointer to its associated data class, and provides event handlers to its events and responds with graphics and animations.

    Contains the following controls:

    • GameShape: This is the graphical representation of the Game class. Doesn’t have a lot of graphics logic, but it contains a list of other graphical representations of the decks and cards that exist in the associated game. It provides utility functions to find a shape that represents a card or deck data object.
    • DeckShape: This is the graphical representation of the Deck class. Handles the positioning of its contained cards according to a set of rules. Like drawing vertically and with a fixed space between cards and a maximum space for the whole deck.
    • CardShape: This is the graphical representation of the Card class. Provide animations to card events, mouse events, and drag and drop behaviors.
  • Solitaire

    This is the Solitaire game. It only contains the main page with the logic of the game in the code-behind.

  • SpiderSolitaire

    This is the Spider Solitaire game. It only contains the main page with the logic of the game in the code-behind.


I’m thinking of expanding these libraries to include game logic that facilitates computer AI players and multiplayer network options. I’ll do this if I have time, but if anyone of you can implement these features, that would make me very happy to know.

QuestionPorting to WPF? Pin

This was an excellent article, very well done.
I am trying to port this library to WPF for use in desktop applications.

I had to make a few modifications just to get the app to build & run with WPF. For instance, I have to access the storyboard via this.Resources["aniFlipStart"] and so forth. Also, WPF wanted to stretch your cards image to fit the entire size of the canvas so I had to specify the dimensions for the image and set the FillMode to Uniform to get that to work.

Finally, had to set the Canvas.Top and Canvas.Left values for the CardShape user control because the animations were erroring out saying that NaN was not a valid point of origin.

I have now run into a major snag:

It seems that under WPF, after animating an object, subsequent calls to Canvas.SetLeft or Canvas.SetTop no longer work (i.e. they have no effect). Thus, I am unable to drag a card from one deck to another.

Essentially, the card position is never updated because SetLeft and SetTop have no effect.

It seems that the aniFlipStart and aniFlipEnd storybards are holding onto the objects or preventing their left & top coordinates from changing.

I tried implementing the completed events and setting the FillBehavior of the storyboards to Stop but that did not help.

Do you have any ideas?
