Xaml 在WPF7中创建圆形按钮

我正试图得到一个圆形的播放按钮，就像音乐中心中的按钮一样（即，带有triancle的圆圈）。 我在App.Xaml中定义了两个资源

• PlayIcon-定义图标的路径
• RoundButton-从中拉出的圆形按钮

按钮在按钮外部呈现，路径在按钮外部呈现，但我无法在按钮内部呈现图标。我很确定我错过了一些简单/愚蠢的东西，但我看不出有什么问题。我在下面包含了一个简单的page.xaml和我的app.xaml

您可以节省一些时间和精力，并使用来自的

RoundButton

控件，这也是主题友好的。也就是说，我认为问题可能是您试图在多个位置使用路径，而我认为您在Silverlight中无法为WP7使用路径（很高兴在这里被证明是错误的）。因此，您可以只使用Windows Phone Toolkit附带的播放图标。
