如何使用Roslyn的OpenSolutionAsync解决所有引用？

Question

我正在尝试使用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和解决参考。 通过这个问题和这个问题的结合 ，我得出了这个部分解决方案：

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();
    }
  }
}

这个程序的日志对我来说太大了，但是工作只适用于某些项目。 例如，rosyln \\ src \\ compilers \\ Core \\ Desktop \\ CodeAnalysis.Desktop.csproj没有错误，但roslyn \\ src \\ Compilers \\ CSharp \\ Portable \\ CSharpCodeAnalysis.csproj具有：

......还有很多其他人。 在我看来，任何方式我都可以为任意项目/解决方案做这项工作会非常hacky。 我错过了什么吗？

Answer 1

我正在考虑在MSBuild目标中修复此问题，但与此同时，以下解决方法应解决此问题。 而不是使用：

MSBuildWorkspace.Create();

使用：

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

Answer 2

如果项目针对的是“完整”.NET框架，则只需添加façade引用。 因此，如果您首先查看现有引用，如果有任何引用来自Reference Assemblies \\ Microsoft.NETPortable \\ v4.5 \\ Profile \\ ...那么您不需要添加它们。
