一．总结.声明
　　关于本WPF，本人也只能算是一个刚入门的，在学习中和工作中，学习、借鉴了很多网友的文章和开源的项目的知识。发现提供实际项目开发需要的基础控件、样式的文章大都比较散，不成系列。因此基于现在项目中使用的基础UI库，写了这个系列，希望对有需要的人有所帮助。
　　本系列包括本文共15篇，就到此为止了。关于一些问题再次说明一下：
每一篇文章中都给出了基本所有主要代码，目的仅供参考学习，由于目前还是公司在使用中的项目，因此不便提供完整项目源码，有需要的同学还是多动动手吧！

对于确实需要源码参考学的，推荐开源项目MahApps.Metro（http://mahapps.com/），我在那里面学习借鉴了很多，本系列中不少样式中都有她（就是她）的影子。

本文会把一些额外遗漏的资源或代码一并提供出来
二．附录.本系列补充资源
2.1附加属性
　　很多样式中使用了附加属性来对基础控件扩展，ControlAttachProperty.cs所有代码：

    /// 公共附加属性
    /// </summary>
