警告 NETSDK1080：面向 .NET Core 3.0 或更高版本时，不需要对 Microsoft.AspNetCore.App 的 PackageReference

Question

如何修复在通过dotnet test从命令行运行 .NET Core 测试时收到的令人讨厌的警告？

dotnet --version返回3.1.101 。

 $ dotnet test watch : Started C:\\Program Files\\dotnet\\sdk\\3.1.101\\Sdks\\Microsoft.NET.Sdk\\targets\\Microsoft.NET.Sdk.DefaultItems.targets(151,5): warning NETSDK1080: A PackageReference to Microsoft.AspNetCore.App is not necessary when targeting .NET Core 3.0 or higher. If Microsoft.NET.Sdk.Web is used, the shared framework will be referenced automatically. Otherwise, the PackageReference should be replaced with a FrameworkReference.

这是我的SmartHome.API.Test.csproj样子。

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>

    <IsPackable>false</IsPackable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="FluentAssertions" Version="5.10.0" />
    <PackageReference Include="Microsoft.NET.Test.Sdk" Version="16.2.0" />
    <PackageReference Include="MongoDB.Driver" Version="2.10.1" />
    <PackageReference Include="xunit" Version="2.4.0" />
    <PackageReference Include="xunit.runner.visualstudio" Version="2.4.0" />
    <PackageReference Include="coverlet.collector" Version="1.0.1" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\SmartHome.API\SmartHome.API.csproj" />
    <ProjectReference Include="..\SmartHome.Models\SmartHome.API.Models.csproj" />
  </ItemGroup>

</Project>

这就是SmartHome.API.csproj ，它似乎是问题的根源。

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="FluentValidation" Version="8.6.1" />
    <PackageReference Include="Microsoft.AspNetCore.App" Version="2.2.8" />
    <PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="3.1.1" />
    <PackageReference Include="MongoDB.Driver" Version="2.10.1" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\SmartHome.Models\SmartHome.API.Models.csproj" />
  </ItemGroup>

</Project>

Answer 1

将Microsoft.AspNetCore.App (2.2.8) 中的包依赖项更改为SmartHome.API.csproj的FrameworkReference为我解决了这个问题，但代价是引入了一个新的问题。

初始修复

+  <ItemGroup>                                                                                                                         
+    <FrameworkReference Include="Microsoft.AspNetCore.App" />                                                                         
+  </ItemGroup>                                                                                                                        
+                                                                                                                                      
   <ItemGroup>                                                                                                                         
     <PackageReference Include="FluentValidation" Version="8.6.1" />                                                                   
-    <PackageReference Include="Microsoft.AspNetCore.App" Version="2.2.8" />                                                           
     <PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="3.1.1" />                                      
     <PackageReference Include="MongoDB.Driver" Version="2.10.1" />                                                                    
   </ItemGroup>                                                                                                                        

新警告

我开始看到一个新警告：

 C:\\Program Files\\dotnet\\sdk\\3.1.101\\Sdks\\Microsoft.NET.Sdk\\targets\\ Microsoft.NET.Sdk.FrameworkReferenceResolution.targets(39,5): warning NETSDK1086: A FrameworkReference for 'Microsoft.AspNetCore.App' was included in the project. This is implicitly referenced by the .NET SDK and you do not typically need to reference it from your project. For more information, see https://aka.ms/sdkimplicitrefs

最终修复

...所以我最终完全删除了"Microsoft.AspNetCore.App"引用。 现在构建是无警告的！

即文件看起来像这样：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="FluentValidation" Version="8.6.1" />
    <PackageReference Include="Microsoft.AspNetCore.Authentication.JwtBearer" Version="3.1.1" />
    <PackageReference Include="MongoDB.Driver" Version="2.10.1" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\SmartHome.Models\SmartHome.API.Models.csproj" />
  </ItemGroup>

</Project>
