在 VS2017 中针对多个框架时发布失败

Question

在 Visual Studio 2017 项目 (netcoreapp1.1;net462) 中针对多个框架时

每次我尝试发布时都会失败并出现错误：

"The 'Publish' target is not supported without specifying a target framework. The current project targets multiple frameworks, please specify the framework for the published application"

我已经准备好属性组条件，但我还需要对 'specify the framework for the published application' 做些什么。我错过了什么吗？

进一步 - 项目编译正常。另外，值得注意的是，它是一个在 VS 2015 中创建并转换为 VS 2017 项目的项目。

这是.csproj:

<Project Sdk="Microsoft.NET.Sdk.Web">
  <PropertyGroup>
    <TargetFrameworks>netcoreapp1.1;net462</TargetFrameworks>
    <PreserveCompilationContext>true</PreserveCompilationContext>

    <OutputType>Exe</OutputType>
    <PackageId>Project.WebApp</PackageId>
    <RuntimeFrameworkVersion Condition=" '$(TargetFramework)' == 'netcoreapp1.1' ">1.1.1</RuntimeFrameworkVersion>
  </PropertyGroup>
  <ItemGroup>

    <ProjectReference Include="..\Proj.Web.Models\Proj.Web.Models.csproj" />
    <ProjectReference Include="..\Proj.Services.Client\Proj.Services.Client.csproj" />

  </ItemGroup>
  <ItemGroup Condition=" '$(TargetFramework)' == 'net462' ">
    <Reference Include="System" />
    <Reference Include="Microsoft.CSharp" />
  </ItemGroup>
  <Target Name="PrepublishScript" BeforeTargets="PrepareForPublish" Condition=" '$(IsCrossTargetingBuild)' != 'true' ">
    <Exec Command="bower install" />
    <Exec Command="dotnet bundle" />
  </Target>
  <ItemGroup>
    <DotNetCliToolReference Include="BundlerMinifier.Core" Version="2.2.301" />
  </ItemGroup>
</Project>

这里还有发布配置文件，它似乎指定了发布框架：

  </PropertyGroup>
</Project>

编辑：对我有用的解决方案 我尝试了仅使用命令行并指定要发布的版本的@Stan88 解决方案。这对我不起作用，因为我的 PrepublishScript 由于某种原因失败了。

最后对我有用的基本上是编辑我的 .csproj 文件以仅针对 netcoreapp1.1 框架。然而，最后我意识到我的 PrepublishScript 有问题并最终删除了 .csproj 文件中对它的引用 - 所以最后我认为如果不是因为预发布疯狂，Stan88 的命令行解决方案会起作用，因此，标记为正确.

这是我的 .csproj 最终的样子。

Answer 1

您一次只能发布一个框架，因此您必须在执行 dotnet publish 命令时指定要发布的目标框架。

dotnet publish -f=netcoreapp1.1

或

dotnet publish -f=net462

在 VS2017 中针对多个框架时发布失败
