c# - 元素 中的属性 "Include"无法识别

Question

我创建了一个 Directory.Build.props通过右键单击“解决方案资源管理器”上的“解决方案”，创建一个 XML 文件并为其命名。然后我输入此 XML 并尝试构建，但遇到了错误:

<Project>
    <PropertyGroup>
        <Version>1.2.3</Version>
        <Authors>John Doe</Authors>
        <PackageReference Include="Microsoft.CodeAnalysis.NetAnalyzers" Version="6.0.0">
            <PrivateAssets>all</PrivateAssets>
            <IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
        </PackageReference>
    </PropertyGroup>
</Project>

错误说: The attribute "Include" in element <PackageReference> is unrecognized.和

Project "C:\redacted\Directory.Build.props" was not imported by "C:\Program Files\Microsoft Visual Studio\2022\Enterprise\MSBuild\Current\Microsoft.Common.props" at (33,3), due to the file being invalid. ProjectName C:\Users\me\source\redacted\ProjectName\Directory.Build.props   33  

我在这里很困惑。其他文章说要找到 MSBuild，我知道它在我的计算机上。在我添加 XML 之前，构建工作得很好。任何指导将不胜感激!顺便说一句，我目前使用的是 Visual Studio 2022。

PackageReference 元素需要位于 ItemGroup 中 - 您已将其置于 PropertyGroup 中。它应该看起来像这样:

<Project>
    <PropertyGroup>
        <Version>1.2.3</Version>
        <Authors>John Doe</Authors>
    </PropertyGroup>

    <ItemGroup>
        <PackageReference Include="Microsoft.CodeAnalysis.NetAnalyzers" Version="6.0.0">
            <PrivateAssets>all</PrivateAssets>
            <IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
        </PackageReference>
    </ItemGroup>
</Project>
