我将Microsoft Visual Studio 2015 Professional与Xamarin一起使用(我是Xamarin的新用户),当我打开Package Manager Console时,我收到错误消息:您可以在下图中看到You cannot call a method on a null-valued expression:
Microsoft Visual Studio 2015 Professional
Xamarin
Package Manager Console
You cannot call a method on a null-valued expression
关于如何解决这个问题的任何想法?
