问题描述
我在链接到 SDK 程序集并构建项目时遇到此异常:
I'm encountering this exception when linking to SDK assemblies and building the project:
Java.Interop.Tools.Diagnostics.XamarinAndroidException:错误 XA2006:无法解析对Microsoft.AspNetCore.Http.Features.Authentication.IAuthenticationHandler"的引用(在程序集Microsoft.AspNetCore.Http,版本=2.2.0.0,Culture=neutral,PublicKeyToken=adb9793829ddae60'),范围为'Microsoft.AspNetCore.Http.Features,Version=2.2.0.0,Culture=neutral,PublicKeyToken=adb9793829ddae60'.当作用域与定义的程序集不同时,通常意味着类型被转发.
为了在 Xamarin 中使用 Signalr,我添加了 Signalr.Client v. 3.1.2.
I've added Signalr.Client v. 3.1.2 for using Signalr in Xamarin.
这是 PCL csproj:

project.assets.json 文件对旧版本的 Microsoft.AspNetCore.Http.Features 有两个依赖
The project.assets.json file has two dependencies on older version of Microsoft.AspNetCore.Http.Features
"Microsoft.AspNetCore.Http.Abstractions/2.2.0": {
"type": "package",
"dependencies": {
"Microsoft.AspNetCore.Http.Features": "2.2.0",
"System.Text.Encodings.Web": "4.5.0"
},
"compile": {
"lib/netstandard2.0/Microsoft.AspNetCore.Http.Abstractions.dll": {}
},
"runtime": {
"lib/netstandard2.0/Microsoft.AspNetCore.Http.Abstractions.dll": {}
}
},
和
"Microsoft.AspNetCore.Hosting.Server.Abstractions/2.2.0": {
"type": "package",
"dependencies": {
"Microsoft.AspNetCore.Http.Features": "2.2.0",
"Microsoft.Extensions.Configuration.Abstractions": "2.2.0"
},
"compile": {
"lib/netstandard2.0/Microsoft.AspNetCore.Hosting.Server.Abstractions.dll": {}
},
"runtime": {
"lib/netstandard2.0/Microsoft.AspNetCore.Hosting.Server.Abstractions.dll": {}
}
},
其他都是指 3.1.2 版本.
All others refer to 3.1.2 version.
请帮助我确定是否应该使用任何其他版本的软件包,或者对其中任何一个使用跳过链接程序集".
Please help me on whether I should use any other versions of the packages, or maybe using "Skip linking assemblies" with any of them.
谢谢

错误信息
错误 XA2006:无法解析对'Microsoft.AspNetCore.Http.Features.Authentication.IAuthenticationHandler'(在程序集 'Microsoft.AspNetCore.Http, Version=2.2.0.0 中定义,文化=中性,PublicKeyToken=adb9793829ddae60') 与范围'Microsoft.AspNetCore.Http.Features, 版本=2.2.0.0,文化=中性,PublicKeyToken=adb9793829ddae60'.
以及 project.assets.json 中的条目:
and the entry in the project.assets.json:
"Microsoft.AspNetCore.Http.Abstractions/2.2.0": {
"type": "package",
"dependencies": {
"Microsoft.AspNetCore.Http.Features": "2.2.0",
"System.Text.Encodings.Web": "4.5.0"
},
"compile": {
"lib/netstandard2.0/Microsoft.AspNetCore.Http.Abstractions.dll": {}
},
"runtime": {
"lib/netstandard2.0/Microsoft.AspNetCore.Http.Abstractions.dll": {}
}
},
表明您仍然使用旧的 asp.net core 2.2 参考.
shows that you still use an old asp.net core 2.2 reference.
共享项目显示是否被引用:
<PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.2.0" />
并将其与 3.1.2 引用混合
and mixing it with 3.1.2 references
<PackageReference Include="Microsoft.AspNetCore.Http.Features" Version="3.1.2" />
导致您的问题.
在此处删除Microsoft.AspNetCore.Mvc"条目以修复它.
Remove here the "Microsoft.AspNetCore.Mvc" entry to fix it.
