使用Roslyn编译解决方案时核心类型的错误

我正在尝试使用Roslyn（Microsoft.CodeAnalysis.CSharp 2.8.2和朋友）编译一个针对.NET Framework 4.6的几个C＃项目的解决方案 .

有问题的解决方案在VS2017中构建得很好，但是当我尝试通过Roslyn进行编译时，我遇到了大量基本核心类型的错误，例如“无法找到类型或命名空间名称'AssemblyTitleAttribute'” .

编辑：也许更重要的是，一旦解决方案打开，MSBuildWorkspace本身就会发出诊断信息 . 它们看起来像这样：

使用以下消息处理文件'C：\ dev \ MySolution \ My.Assembly.Name \ My.Assembly.Name.csproj'时Msbuild失败：C：\ Program Files（x86）\ Microsoft Visual Studio \ 2017 \ Professional \ MSBuild \ 15.0 \ Bin \ Microsoft.Common.CurrentVersion.targets：（1603,5）：无法从程序集“C：\ Program Files（x86）\ Microsoft Visual Studio \ 2017 \ Professional \ Common7中实例化”GetReferenceNearestTargetFrameworkTask“任务\ IDE \ CommonExtensions \微软\的NuGet \ NuGet.Build.Tasks.dll” . 请验证是否使用与计算机上安装的Microsoft.Build.Framework程序集相同的Microsoft.Build.Framework程序集版本构建了任务程序集，并确保主机应用程序没有缺少Microsoft.Build.Framework的绑定重定向 . 无法将“NuGet.Build.Tasks.GetReferenceNearestTargetFrameworkTask”类型的对象强制转换为“Microsoft.Build.Framework.ITask” . C：\ Program Files（x86）\ Microsoft Visual Studio \ 2017 \ Professional \ MSBuild \ 15.0 \ Bin \ Microsoft.Common.CurrentVersion.targets：（1603,5）：“GetReferenceNearestTargetFrameworkTask”任务已被声明或使用不正确，或者施工期间失败 . 检查任务名称和程序集名称的拼写 .

这是我正在使用的代码：

var solution = await MSBuildWorkspace.Create().OpenSolutionAsync(@"C:\path\to\solution.sln");
var project = solution.Products.Single(p => p.Name == "ProjectName");
var compilation = await project.GetCompilationAsync();
var diagnostics = compilation.GetDiagnostics()
    .Where(d => !d.IsSuppressed && d.Severity == DiagnosticSeverity.Error)
    .ToArray();
foreach (var diagnostic in diagnostics) { /* print */ }

What am I doing wrong?

到目前为止我尝试过的事情：

• 添加外观DLL元数据引用：

var metadataReferenceDlls = Directory.GetFiles(@"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6\Facades\", "*.dll");
    var metadataReferences = metadataReferenceDlls.Select(f => MetadataReference.CreateFromFile(f)).ToArray();
    foreach (var projectId in solution.ProjectIds.ToArray())
    {
        solution = solution.AddMetadataReferences(projectId, metadataReferences);
    }

• 添加当前运行时元数据引用（与上面相同，但使用 Path.GetDirectoryName(typeof(object).Assembly.Location) 作为搜索路径） . 这个作品！但是，它感觉不理想，因为我仍然需要手动解析所有引用的DLL .

• 安装Microsoft.Build.Locator并提前调用 MSBuildLocator.RegisterDefaults();

同时发布在Roslyn的GitHub上：https://github.com/dotnet/roslyn/issues/29170
