Question

我已经关注了以下链接中的所有内容: https://developer.xamarin.com/guides/xamarin-forms/user-interface/navigation/master-detail-page/我写的代码可以在这里找到:http://github.com/foyzulkarim/XamarinFormsDrawer我使用 UWP 项目在我的 Windows 10 本地计算机中成功部署了相同的项目，但是每当我想在模拟器或我的设备中部署时，它都会抛出以下异常。

解决方案是，我需要更新包，只更新 Xamarin.Forms 包。就像下图一样。

更新后，packages.config 文件应该如下所示

<?xml version="1.0" encoding="utf-8"?>
<packages>
  <package id="Xamarin.Android.Support.Animated.Vector.Drawable" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.Design" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v4" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.AppCompat" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.CardView" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.MediaRouter" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.v7.RecyclerView" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Android.Support.Vector.Drawable" version="23.3.0" targetFramework="monoandroid60" />
  <package id="Xamarin.Forms" version="2.3.2.127" targetFramework="monoandroid60" />
</packages>

并忽略下面的其余包。
