Windows Phone 7.1的活动瓷砖背景图像未设置

我想改变背景图像（正面和背面）的活动瓷砖的Windows Phone 7.1应用程序，但背景图像从未设置。我已经将图像添加到项目中，并确保在Uri（）构造函数中正确指定它们的名称。我似乎无法检测到问题。这是代码。Windows Phone 7.1的活动瓷砖背景图像未设置

只有当瓦片翻转时才会看到'BackBackgroundImage' – csharpwinphonexaml

@verdesrobert是的。但是，在发生翻转时，“BackBackgroundImage”仍然是默认的红色颜色 – Fourth

请编辑此代码，以便其他任何碰到它的人更容易。对于这个特殊问题，将Bulid Action设置为“content”是解决方案。您仍然可以在此之后提供链接 – Fourth

您应该在问题中发布构建操作的屏幕截图，当它不起作用时。 – csharpwinphonexaml
