【问题描述】：
在 Visual Studio 2017 项目 (netcoreapp1.1;net462) 中针对多个框架时
每次我尝试发布发布都会失败并出现错误：
“不指定目标框架不支持‘发布’目标。当前项目针对多个框架，请为发布的应用指定框架”
我的属性组条件已经到位，但我还需要做什么来“为已发布的应用程序指定框架”。我错过了什么吗？
进一步 - 项目编译良好。另外，值得注意的是，它是在 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>

</Target>
<ItemGroup>
<DotNetCliToolReference Include="BundlerMinifier.Core" Version="2.2.301" />
</ItemGroup>
</Project>
这里也是发布配置文件，它似乎指定了一个发布框架：
<?xml version="1.0" encoding="utf-8"?>

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，最后我最终意识到我的 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 prepublish 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。
