如何解决与Roslyn的OpenSolutionAsync有关的所有引用？

Question

我试图用OpenSolutionAsync打开RoslynLight.sln，然后遍历所有项目。为了我的目的，我需要一个语义模型并解析引用。通过这种issue和this question组合，我已经到达此部分解决：

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using Microsoft.CodeAnalysis; 
using Microsoft.CodeAnalysis.MSBuild; 
using System.IO; 

namespace OpenRoslyn 
{ 
    class Program 
    { 
    static void Main(string[] args) 
    { 

     var msbw = MSBuildWorkspace.Create(); 
     var sln = msbw.OpenSolutionAsync(@"C:\Users\carr27\Documents\GitHub\roslyn\src\RoslynLight.sln").Result; 
     //var proj = sln.Projects.First(x => x.Name == "CodeAnalysis.Desktop"); 
     var messages = new List<string>(); 
     foreach (var p in sln.Projects) 
     { 
     Console.WriteLine(p.FilePath); 
     messages.Add(p.FilePath); 
     var facadesDir = @"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\.NETFramework\v4.6\Facades\"; 
     var proj = p.AddMetadataReference(MetadataReference.CreateFromAssembly(typeof(object).Assembly)); 
     proj = proj.AddMetadataReference(MetadataReference.CreateFromFile(facadesDir + "System.Runtime.dll")); 
     proj = proj.AddMetadataReference(MetadataReference.CreateFromFile(facadesDir + "System.Runtime.Extensions.dll")); 
     proj = proj.AddMetadataReference(MetadataReference.CreateFromFile(facadesDir + "System.IO.dll")); 
     proj = proj.AddMetadataReference(MetadataReference.CreateFromFile(facadesDir + "System.Threading.Tasks.dll")); 
     proj = proj.AddMetadataReference(MetadataReference.CreateFromFile(facadesDir + "System.Text.Encoding.dll")); 
     proj = proj.AddMetadataReference(MetadataReference.CreateFromFile(facadesDir + "System.Reflection.dll")); 
     try 
     { 
      var cu = proj.GetCompilationAsync().Result; 
      // here I would do useful work, but for know I just get diagnostics 
      foreach (var e in cu.GetDiagnostics().Where(x => x.Severity == DiagnosticSeverity.Error)) 
      { 
      Console.WriteLine("{0}: {1}", e.Location, e.GetMessage()); 
      messages.Add(String.Format("{0}: {1}", e.Location, e.GetMessage())); 
      } 
     } 
     catch (AggregateException e) 
     { 
      foreach(var ie in e.InnerExceptions) 
      { 
      Console.WriteLine(ie.Message); 
      messages.Add(ie.Message); 
      } 

     } 
     catch (Exception e) 
     { 
      Console.WriteLine(e.Message); 
      messages.Add(e.Message); 
     } 
     } 
     File.WriteAllLines("log.txt", messages); 
     Console.WriteLine("done."); 
     Console.ReadKey(); 
    } 
    } 
} 

日志对这一计划是太大了，我张贴，但工作只有大约可用于特定项目。例如，rosyln的\ src \编译\核心\桌面\ CodeAnalysis.Desktop.csproj没有错误，但罗斯林的\ src \编译\ CSHARP \便携式\ CSharpCodeAnalysis.csproj有：

...等等其他。在我看来，任何可以让这项工作成为任意项目/解决方案的方法都会非常黑客。我错过了什么吗？

Answer 1

如果项目的目标是“完整”.NET框架，则只需添加外观引用。因此，如果您首先查看现有的引用，如果有任何引用来自引用程序集\ Microsoft.NETPortable \ v4.5 \ Profile \ ...，那么您不需要添加它们。

Answer 2

我正在寻找解决这个问题的MSBuild目标，但与此同时，下面的解决方法应该解决这个问题。而不是使用：

MSBuildWorkspace.Create(); 

使用：

MSBuildWorkspace.Create(new Dictionary<string, string> { { "CheckForSystemRuntimeDependency", "true" } });
