本文介绍了将 dotnetcore 项目迁移到 1.0.4 后出现“dotnet build"错误的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我一直在尝试在迁移的 .net 核心项目(从 1.0.0-preview2-003131 到 1.0.4)上运行 dotnet build 命令.我按照此处中提到的迁移项目的步骤进行了操作，并且解决方案使用 Visual Studio 2017 构建.但是，使用 dotnet CLI 命令dotnet build"给我以下错误:

<块引用>

C:程序Filesdotnetsdk1.0.4Microsoft.Common.CurrentVersion.targets(2867,5):错误 MSB4216:无法运行GenerateResource"任务，因为MSBuild 无法创建或连接到具有运行时CLR4"的任务主机和架构x86".请确保 (1) 请求的运行时和/或架构在机器上可用，并且 (2)所需的可执行文件C:Program Filesdotnetsdk1.0.4MSBuild.exe"存在并且可以运行.

我之前迁移了几个其他服务，在整理了几个包依赖项后，CLI 命令运行得很好.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 命令来为我拥有的 CI/CD 设置工作.非常感谢您对破译和修复此错误的任何帮助.

系统详细信息:

  1. Visual Studio 2017 社区
  2. dotnet --version --> 1.0.4

我遵循的迁移步骤:

  1. 更改 global.json 中的 sdk 版本
  2. 运行 dotnet migrate 命令
  3. 在 VS 2017 中打开解决方案并构建它.构建成功.

我认为这是一个 dotnet 核心项目.显然(甚至在运行 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:

原始解决方案编译和构建没有任何问题.我对此有点陌生，但我对一个解决方案如何针对两个单独的 dotnet 版本进行编译(以及为什么在迁移时构建过程失败)感到困惑.我应该单独运行迁移命令吗?(仅适用于 .xproj 项目)?

解决方案

包含在 .NET Core CLI 中的 MSBuild .NET Core 构建能够在 Windows 机器上构建经典项目，只要它们面向 .NET Framework >= 4.0，安装了参考程序集并且没有使用特殊的目标/任务.

在您的情况下，您尝试编译与主机 MSBuild 实例架构不同的资源.从即将推出的 2.0 工具开始，这在基于 SDK 的项目中得到解决，但经典项目依赖 MSBuild 使用不同的 CLR 启动附加进程 - 这在 .NET Core 上不受支持.

解决这个问题的简单方法是不使用 dotnet 命令来恢复/构建解决方案，而是使用与 Visualstudio 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，将其添加到旧"项目中的 :

<GenerateResourceMSBuildArchitecture>CurrentArchitecture</GenerateResourceMSBuildArchitecture><GenerateResourceMSBuildRuntime>CurrentRuntime</GenerateResourceMSBuildRuntime></PropertyGroup>

MSBuild 的 GitHub 存储库上有一个关于此问题的问题.

I've been trying to run the dotnet build command on a migrated .net core project (from 1.0.0-preview2-003131 to 1.0.4). I followed the steps for migrating the project mentioned here, and the solution builds using Visual Studio 2017. However, using the dotnet CLI command 'dotnet build' gives me the following error:

C:Program Filesdotnetsdk1.0.4Microsoft.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 Filesdotnetsdk1.0.4MSBuild.exe" exists and can be run.

I have migrated a couple of other services earlier, and after sorting out a couple of package dependencies, the CLI commands worked just fine. I checked the sdk location mentioned in the error, and I couldn't find MSBuild.exe (I did find the MSBuild.dll and the MsBuild.deps file though). I need the CLI commands to work for the CI/CD setup that I have. Any help with deciphering and fixing this error is much appreciated.

System Details:

  1. Visual Studio 2017 Community
  2. dotnet --version --> 1.0.4

The migration steps I followed:

  1. Changed the sdk version in global.json
  2. Ran the dotnet migrate command
  3. Opened the solution in VS 2017 and built it. The build was successful.

Edit: I assumed that this was a dotnet core project. Apparently (even before running the dotnet migrate command), one of the projects inside this solution was already targeting .Net 4.5.2. The relevant .csproj file is below:

The original solution compiles and builds without any problems. I'm a bit new to this, but I'm a bit confused as to how a solution which has projects targeting two separate vesions of dotnet compiles (and why, on migrating, the build process fails). Should I be running the migrate commands separately? (only on .xproj projects)?

解决方案

The .NET Core build of MSBuild that is included in the .NET Core CLI is capable of building classic projects on windows machines as well as long as they target .NET Framework >= 4.0, reference assemblies are installed and no special targets / tasks are used.

In your case, you tried to compile a resource with a different architecture than the host MSBuild instance is. This is worked around in SDK-based projects beginning in the upcoming 2.0 tools but classic projects rely on MSBuild to launch an additional process using a different CLR - which is not supported on .NET Core.

The easy way to work around it is to not use the dotnet commands to restore / build the solution, but their msbuild equivalents using the msbuild.exe installed with visual studio using the developer command prompt. (e.g. => msbuild /t:Restore, msbuild, msbuild /t:Publish /p:Configuration=Release etc.).

Another workaround would be to edit the problematic csproj file to add this to the <Project> in the "old" project:

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

There is an issue on MSBuild's GitHub repo about this problem.
