在 TFS 中将具有多个目标框架的项目作为 NuGet 包生成

Question

我想在其中一个 TFS 生成步骤中生成我的 NuGet 包。

由于 TFS NuGet 步骤当前不支持 .NET 标准 2.0，因此我在 MSBuild 调用中使用/t:pack作为生成参数。

当我只使用一种TargetFramework它工作正常时。我的程序集也获得一个版本和我的 NuGet 包。 即使我在.NET Standard 2.0中使用AssemblyInfo.cs - 在本答案中进行了解释。

到目前为止没问题，但是如果我现在想在两个不同的TargetFrameworks上构建，例如<TargetFramework>netstandard2.0;net45</TargetFramework>我的NuGet包将不会获得版本。

所以最终这是有效的，并且正在生成一个版本化的NuGet文件。

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>netstandard2.0</TargetFramework>
<GeneratePackageOnBuild>false</GeneratePackageOnBuild>
<GenerateNuspecDependsOn>$(GenerateNuspecDependsOn);ReadPackageVersionFromOutputAssembly</GenerateNuspecDependsOn>
<GenerateAssemblyInfo>false</GenerateAssemblyInfo>
</PropertyGroup>
<Target Name="ReadPackageVersionFromOutputAssembly" DependsOnTargets="Build">
<GetAssemblyIdentity AssemblyFiles="$(TargetPath)">
<Output TaskParameter="Assemblies" ItemName="PackAssembly" />
</GetAssemblyIdentity>
<PropertyGroup>
<PackageVersion>%(PackAssembly.Version)</PackageVersion>
</PropertyGroup>
</Target>
<ItemGroup>
<Compile Remove="AccessControl**" />
<EmbeddedResource Remove="AccessControl**" />
<None Remove="AccessControl**" />
</ItemGroup>
<ItemGroup>
<Compile Include="..commonVersion.cs" Link="PropertiesVersion.cs" />
</ItemGroup>
<ItemGroup>
<PackageReference Include="System.Threading.Tasks.Dataflow" Version="4.8.0" />
</ItemGroup>
<ItemGroup>
<Reference Include="MyEngine">
<HintPath>..libsNetStandardMyEngine.dll</HintPath>
</Reference>
</ItemGroup>
<ItemGroup>
<Folder Include="Properties" />
</ItemGroup>
</Project>

所以这是我当前的 .csproj 文件。这也会生成，还会生成 NuGet 文件。但在这种情况下，我的 NuGet 文件未版本控制。为什么会这样，我该如何解决？

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFrameworks>netstandard2.0;net45</TargetFrameworks>
<GeneratePackageOnBuild>false</GeneratePackageOnBuild>
<GenerateNuspecDependsOn>$(GenerateNuspecDependsOn);ReadPackageVersionFromOutputAssembly</GenerateNuspecDependsOn>
<GenerateAssemblyInfo>false</GenerateAssemblyInfo>
</PropertyGroup>
<Target Name="ReadPackageVersionFromOutputAssembly" DependsOnTargets="Build">
<GetAssemblyIdentity AssemblyFiles="$(TargetPath)">
<Output TaskParameter="Assemblies" ItemName="PackAssembly" />
</GetAssemblyIdentity>
<PropertyGroup>
<PackageVersion>%(PackAssembly.Version)</PackageVersion>
</PropertyGroup>
</Target>
<ItemGroup>
<Compile Remove="AccessControl**" />
<EmbeddedResource Remove="AccessControl**" />
<None Remove="AccessControl**" />
</ItemGroup>
<ItemGroup>
<Compile Include="..commonVersion.cs" Link="PropertiesVersion.cs" />
</ItemGroup>
<ItemGroup>
<PackageReference Include="System.Threading.Tasks.Dataflow" Version="4.8.0" />
</ItemGroup>
<ItemGroup Condition="'$(TargetFramework)' == 'netstandard2.0'">
<Reference Include="MyEngine">
<HintPath>..libsNetStandardMyEngine.dll</HintPath>
</Reference>
</ItemGroup>
<ItemGroup Condition="'$(TargetFramework)' == 'net45'">
<Reference Include="MyEngine">
<HintPath>..libsNET45MyEngine.dll</HintPath>
</Reference>
</ItemGroup>
<ItemGroup>
<Folder Include="Properties" />
</ItemGroup>
</Project>

可以调整目标以支持多目标，如下所示：

<Target Name="ReadPackageVersionFromOutputAssemblySingleTfm" Returns="@(PackAssembly)" Condition="'$(IsCrossTargetingBuild)' != 'true'">
<GetAssemblyIdentity AssemblyFiles="$(TargetPath)">
<Output TaskParameter="Assemblies" ItemName="PackAssembly" />
</GetAssemblyIdentity>
<PropertyGroup>
<PackageVersion>%(PackAssembly.Version)</PackageVersion>
</PropertyGroup>
</Target>
<Target Name="ReadPackageVersionFromOutputAssemblyMultipleTfms" Condition="'$(IsCrossTargetingBuild)' == 'true'">
<PropertyGroup>
<FirstTargetFramework>$([System.String]::Copy($(TargetFrameworks)).Split(';').GetValue(0))</FirstTargetFramework>
</PropertyGroup>
<MSBuild Projects="$(MSBuildProjectFullPath)" Targets="ReadPackageVersionFromOutputAssemblySingleTfm" Properties="TargetFramework=$(FirstTargetFramework)">
<Output TaskParameter="TargetOutputs" ItemName="PackAssembly" />
</MSBuild>
<PropertyGroup>
<PackageVersion>%(PackAssembly.Version)</PackageVersion>
</PropertyGroup>
</Target>
<Target Name="ReadPackageVersionFromOutputAssembly" DependsOnTargets="Build;ReadPackageVersionFromOutputAssemblySingleTfm;ReadPackageVersionFromOutputAssemblyMultipleTfms" />
