VSCode 的 Omnisharp 1.9.0 扩展无法识别 DotNet Core 的 CSProj 文件

Question

当我尝试在 visual studio 代码中打开 dotNet core 1.1 mvc 项目时，无法识别 csproj 文件，我无法从项目中获取任何符号。

VSCode 显示 "Some projects have trouble loading, please review the output for more details" 的 [警告] 消息。在输出中我收到以下消息：

[warn]: OmniSharp.MSBuild.MSBuildProjectSystem Failed to process project file 'c:\Users\humam\Projects\AM\AM.csproj'. c:\Users\humam\Projects\AM\AM.csproj(1,1) Microsoft.Build.Exceptions.InvalidProjectFileException: The imported project "C:\Program Files (x86)\Microsoft Visual Studio17\BuildTools\MSBuild\Sdks\Microsoft.NET.Sdk.Web\Sdk\Sdk.props" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk. c:\Users\humam\Projects\AM\AM.csproj at Microsoft.Build.Shared.ProjectErrorUtilities.ThrowInvalidProject(String errorSubCategoryResourceName, IElementLocation elementLocation, String resourceName, Object[] args) at Microsoft.Build.Shared.ProjectErrorUtilities.ThrowInvalidProject(IElementLocation elementLocation, String resourceName, Object arg0) at Microsoft.Build.Evaluation.Evaluator4.ExpandAndLoadImportsFromUnescapedImportExpression(String directoryOfImportingFile, ProjectImportElement importElement, String unescapedExpression, Boolean throwOnFileNotExistsError, List1& imports) at Microsoft.Build.Evaluation.Evaluator4.ExpandAndLoadImports(String directoryOfImportingFile, ProjectImportElement importElement) at Microsoft.Build.Evaluation.Evaluator4.EvaluateImportElement(String directoryOfImportingFile, ProjectImportElement importElement) at Microsoft.Build.Evaluation.Evaluator4.PerformDepthFirstPass(ProjectRootElement currentProjectOrImport) at Microsoft.Build.Evaluation.Evaluator4.Evaluate() at Microsoft.Build.Evaluation.Project.Reevaluate(ILoggingService loggingServiceForEvaluation, ProjectLoadSettings loadSettings) at Microsoft.Build.Evaluation.Project.ReevaluateIfNecessary(ILoggingService loggingServiceForEvaluation, ProjectLoadSettings loadSettings) at Microsoft.Build.Evaluation.Project.Initialize(IDictionary2 globalProperties, String toolsVersion, String subToolsetVersion, ProjectLoadSettings loadSettings) at Microsoft.Build.Evaluation.Project..ctor(String projectFile, IDictionary2 globalProperties, String toolsVersion, String subToolsetVersion, ProjectCollection projectCollection, ProjectLoadSettings loadSettings) at Microsoft.Build.Evaluation.ProjectCollection.LoadProject(String fileName, IDictionary2 globalProperties, String toolsVersion) at OmniSharp.MSBuild.ProjectFile.ProjectFileInfo.Create(String projectFilePath, String solutionDirectory, ILogger logger, MSBuildOptions options, ICollection1 diagnostics, Boolean isUnityProject) at OmniSharp.MSBuild.MSBuildProjectSystem.CreateProjectFileInfo(String projectFilePath, Boolean isUnityProject)

知道这个问题的根源是什么吗？

我的环境是 Windows10，包括 VSCode 的 DotNet Core SDK 1.1.0、VSCode 1.12.2 和 Omnisharp 1.9.0 C# 扩展以及其他扩展。

项目是使用 dotnet core 命令创建的 "dotnet new mvc --auth Individual -o AM"。

Answer 1

OmniSharp 似乎加载了目前不支持 .NET Core 项目的 VS 2017 构建工具：https://github.com/Microsoft/msbuild/issues/1697。尝试安装具有 Web 开发/跨平台工作负载的 VS 2017 版本，或者在您的项目中创建一个 omnisharp.json 文件，其中包含：

{
    "msbuild": {
        "msbuildextensionspath": "C:\Program Files\dotnet\sdk\1.0.4\Sdks"
    }
}

然后您需要通过命令行 dotnet restore（因为构建工具也不包含 NuGet 版本）并在 VSCode.

中重新加载项目

Answer 2

我在制作 .NET core 3 项目时偶然发现了同样的问题，这对我有用。

我的 omnisharp.json 文件：

{
    "MSBuild": {
        "UseLegacySdkResolver": true
    }
 }

和我的 global.json（可选，通过 "dotnet --list-sdks" 检查您的 sdk 版本）

{
    "sdk": {
      "version": "3.0.100"
    }
}
