'dotnet build' 将 dotnetcore 项目迁移到 1.0.4 后出错

Question

我一直在尝试运行在已迁移的 .net 核心项目（从 1.0.0-preview2-003131 到 1.0.4）上使用 dotnet build 命令。我按照迁移项目 here 的步骤进行操作，解决方案使用 Visual Studio 2017 构建。但是，使用 dotnet CLI 命令 'dotnet build' 会出现以下错误：

C:\Program Files\dotnet\sdk.0.4\Microsoft.Common.CurrentVersion.targets(2867,5): error MSB4216: Could not run the "GenerateResource" task because MSBuild could not create or connect to a task host with runtime "CLR4" and architecture "x86". Please ensure that (1) the requested runtime and/or architecture are available on the machine, and (2) that the required executable "C:\Program Files\dotnet\sdk.0.4\MSBuild.exe" exists and can be run.

我之前已经迁移了几个其他服务，在整理出几个包依赖项之后，CLI 命令工作得很好。我检查了错误中提到的 sdk 位置，但找不到 MSBuild.exe（不过我确实找到了 MSBuild.dll 和 MsBuild.deps 文件）。我需要 CLI 命令才能为我拥有的 CI/CD 设置工作。非常感谢任何有关破译和修复此错误的帮助。

系统详情：

Visual Studio 2017 社区
dotnet --version --> 1.0.4

我遵循的迁移步骤：

更改了 global.json
运行 dotnet 迁移命令
在 VS 2017 中打开解决方案并构建它。构建成功。

编辑：我认为这是一个 dotnet 核心项目。显然（甚至在运行执行 dotnet migrate 命令之前），该解决方案中的一个项目已经针对 .Net 4.5.2。相关的 .csproj 文件如下：

原方案编译构建没有任何问题。我对此有点陌生，但我对一个解决方案如何针对两个不同的 dotnet 版本进行编译感到困惑（以及为什么在迁移时构建过程失败）。我应该运行单独执行迁移命令吗？（仅限 .xproj 项目）?

Answer 1

.NET Core CLI 中包含的 MSBuild 的 .NET Core 构建能够在 windows 机器上构建经典项目，只要它们以 .NET Framework >= 4.0 为目标，参考程序集已安装且未使用特殊目标/任务。

在您的情况下，您尝试使用与主机 MSBuild 实例不同的体系结构来编译资源。这在即将推出的 2.0 工具开始的基于 SDK 的项目中得到了解决，但经典项目依赖 MSBuild 使用不同的 CLR 启动额外的进程 - 这在 .NET Core 上不受支持。

解决它的简单方法是不使用 dotnet 命令来恢复/构建解决方案，而是使用 [=30] 安装的 msbuild.exe 等价物 msbuild =] 使用开发人员命令提示符。（例如 => msbuild /t:Restore、msbuild、msbuild /t:Publish /p:Configuration=Release 等）。

另一种解决方法是编辑有问题的 csproj 文件，将其添加到 "old" 项目中的 <Project>：

<PropertyGroup Condition="'$(MSBuildRuntimeType)' == 'Core'">
  <GenerateResourceMSBuildArchitecture>CurrentArchitecture</GenerateResourceMSBuildArchitecture>
  <GenerateResourceMSBuildRuntime>CurrentRuntime</GenerateResourceMSBuildRuntime>
</PropertyGroup>
