Xamarin 表单链接器和 Prism.Dryioc

Question

所以，当我们使用 Xamarin Forms 时，我们想要一个小的 apk 大小。为了实现这一点，我们有 Linker 和 Proguard。

但是使用 Prism.Dryioc 我卡住了，我真的不知道如何正确设置我的 Link 配置文件。

<?xml version="1.0" encoding="utf-8" ?>
<linker>
  <assembly fullname="Prism.Forms">
      <type fullname="Prism.Common.ApplicationProvider" preserve="all" />
      <type fullname="Prism.Services.PageDialogService" preserve="all" />
      <type fullname="Prism.Services.DeviceService" preserve="all" />
  </assembly>

   <assembly fullname="Prism.DryIoc.Forms" >
      <namespace fullname="Prism.DryIoc" preserve="all" />
   </assembly>
   <assembly fullname="Prism">
      <namespace fullname="Prism.Ioc" preserve="all" />
   </assembly>
   <assembly fullname="netstandard">
      <namespace fullname="System.Reflection" preserve="all" />
      <namespace fullname="System.Xml" preserve="all" />
   </assembly>
 </linker>

通过上面我得到了这个异常：

谁能帮我找到让 Linker 工作的方法？

我的链接器文件非常错误。我几个小时后修好了。
