我也是windows phone开发的新手。我没有检查整个标签，但您可能会意外更改设计的内容。也许您可以尝试撤消更改或向项目中添加另一个屏幕？（a）我在一个新项目中尝试过。我似乎真的无法解决这个问题。我可以调用pushpin类并生成上面的imports命名空间，但是它的'location'属性没有出现在intellisense中。我希望知道答案，但我不知道。至于代码，您可能知道它很简单：GeoCoordinate myLocation=new GeoCoordinate（39.8666,32.866）；图钉销1=新图钉（）；pin1.位置=我的位置；但我从未在这么少量的学习中遇到过这样的问题：/
