无法在Xamarin上加载System.Reflection.TypeExtensions [英] Cannot load System.Reflection.TypeExtensions on Xamarin
问题描述
我需要在某些Nuget软件包中使用System.Reflection.TypeExtensions.我希望此软件包可在Xamarin Forms项目中使用. 根据 System.Reflection.TypeExtensions ,这应该适用于Xamarin.
I need to use System.Reflection.TypeExtensions in some of my Nuget packages. I want this package to be used within a Xamarin Forms project. According to the nuget package page of System.Reflection.TypeExtensions , this should work with Xamarin.
但是,当我出于测试目的编译我的Android项目时,出现此错误:
However, when I compile my Android project for testing purpose, I got this error :
加载程序集时发生异常:System.IO.FileNotFoundException:无法加载程序集'System.Reflection.TypeExtensions,版本= 4.0.1.0,区域性=中性,PublicKeyToken = b03f5f7f11d50a3a'.也许在Mono for Android配置文件中不存在?
Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'System.Reflection.TypeExtensions, Version=4.0.1.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. Perhaps it doesn't exist in the Mono for Android profile?
我无法弄清楚如何解决此错误,特别是因为其他无法删除的其他人需要此软件包...
I cannot figured it out how to fix this error, especially because this package is required by some other that I cannot remove...
有什么办法解决吗?
这是我的包中的project.json/frameworks:
Here my project.json/frameworks of my package :

}
PS:重新启动Visual Studio无法解决任何问题
PS : rebooting Visual Studio doesn't fix anything
推荐答案
弄清楚会发生什么:我从dotnet5.2输出中选择了DLL. 如果我从net45文件夹中选择DLL,则没有编译问题.
Figured out what happens : I picked the DLL from the dotnet5.2 output. If I choose the DLLs from net45 folder, I have no compilation issue.
尽管如此,我必须搜索为什么在创建nuget包时会选择错误的框架并产生错误.
Altough, I have to search why, when create nuget package, it picks the wrong framework and create errors.
