C# Roslyn没有对System.Runtime的引用

C# Roslyn没有对System.Runtime的引用,c#,roslyn,C#,Roslyn,我正在做一个项目，我们正在使用Roslyn为我们编译一些模板。现在，当我编译模板时，我在CompileResult.Diagnostics中收到多个错误错误是： (21,6): error CS0012: The type 'System.Attribute' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0

我正在做一个项目，我们正在使用Roslyn为我们编译一些模板。现在，当我编译模板时，我在

CompileResult.Diagnostics

中收到多个错误

错误是：

(21,6): error CS0012: The type 'System.Attribute' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
(21,6): error CS0012: The type 'System.Type' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Runtime, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

看到这些错误，我假设我没有正确添加对

System.Runtime

程序集的引用。但是，在检查加载的程序集后，这似乎是正常的

private IEnumerable<MetadataReference> GetGlobalReferences()
{
    var assemblies = new [] 
        {
            typeof(System.Object).Assembly,                         //mscorlib
            typeof(System.Composition.ExportAttribute).Assembly,    //System.Composition (MEF)
            typeof(System.CodeDom.Compiler.CodeCompiler).Assembly,  //System.CodeDom.Compiler
        };

    var refs = from a in assemblies
                select new MetadataFileReference(a.Location);

    return refs.ToList();
}

我错过了什么明显的东西吗？看起来成功编译的所有先决条件都满足了，但显然没有

作为参考，这是我试图编译的（模糊的）代码：

namespace Project.Rules.Generated
{
    using System;
    using System.Runtime;
    using System.Composition;
    using System.CodeDom.Compiler;

    [Export(typeof(IProject))]
    [GeneratedCode("Project Template Compiler", "1.0")]
    public sealed class ProcessPriorityValue : ProjectConcreteClass
    {
        public override void Execute(ProjectExecutionContext ctx)
        {
            CurrentContext = ctx;
        }
    }
}

编辑我在搜索方面有点进步。错误消息中指定的PublicKeyToken与System.Composition程序集的PublicKeyToken匹配。我猜添加所有的程序集可能会解决这个问题。这是正确的，或者至少是解决方案的一部分。通过使用dotPeek，我能够检查不同程序集中存在哪些对象。有了这些知识，我将

GetGlobalReferences（）

方法更改为：

private IEnumerable<MetadataReference> GetGlobalReferences()
{
    var assemblies = new [] 
        {
            typeof(System.Object).Assembly,                                     //mscorlib
            typeof(System.Composition.ExportAttribute).Assembly,                //System.Composition.AttributeModel
            typeof(System.Composition.Convention.ConventionBuilder).Assembly,   //System.Composition.Convention
            typeof(System.Composition.Hosting.CompositionHost).Assembly,        //System.Composition.Hosting
            typeof(System.Composition.CompositionContext).Assembly,             //System.Composition.Runtime
            typeof(System.Composition.CompositionContextExtensions).Assembly,   //System.Composition.TypedParts
            typeof(System.CodeDom.Compiler.CodeCompiler).Assembly,              //System.CodeDom.Compiler
        };

    var refs = from a in assemblies
                select new MetadataFileReference(a.Location);

    return refs.ToList();
}

出于某种原因，代码现在希望使用

System.Composition.Runtime.Export

，而不是

System.Composition.AttributeModel

程序集中定义的ExportAttribute

edit2

我可以确认上面的代码使用的是

System.Composition.Export

，而不是

ExportAttribute

。我通过将

[Export（typeof（IProject）]

更改为

[ExportAttribute（typeof（IProject）]

发现了这一点。由于此更改，返回了原始错误。看起来程序集

System.Composition.AttributeModel

没有正确加载/引用，但是在检查

编译后，我可以看到程序集被引用了，ok
我目前得到的引用程序集包括：

似乎您正在引用一个可移植类库。可移植类库从“System.Runtime.dll”中提取一些基本类型（如object/string/etc）。但是，在桌面框架中，这些类型来自mscorlib.dll。当您使用typeof（object）时.Assembly
，您将获得Roslyn自己版本的对象
。由于Roslyn不是作为可移植类库构建的，这是一个来自mscorlib的类库，并且与您的其他引用的标识不匹配。
根据Dejan在评论部分的请求，我将把我的问题的答案作为真实答案发布

我发现了问题所在！编译器一直都是正确的。of触发了我尝试其他东西。与其使用Facade dll，不如尝试手动引用必要的dll。
GetGlobalReferences
方法现在如下所示：

    var assemblies = new []

    var refs = from a in assemblies 
                select new MetadataFileReference(a.Location);
    var returnList = refs.ToList();

    //The location of the .NET assemblies
    var assemblyPath = Path.GetDirectoryName(typeof(object).Assembly.Location);

    /*

    return returnList;
}

添加（新的MetadataFileReference（Path.Combine（assemblyPath，“System.dll”）））；
添加（新的MetadataFileReference（Path.Combine（assemblyPath，“System.Core.dll”））；
添加（新的MetadataFileReference（Path.Combine（assemblyPath，“System.Runtime.dll”））；
退货清单；
}

在反编译System.Runtime.dll
时，我还了解了为什么不能以任何其他方式引用它。dll是空的，它只包含一些对其他程序集的引用。因此，不能以任何其他方式引用此程序集。
您的评论可能会产生误导。据我所知，是在mscorlib
中，而不是在中>System.Runtime
assembly。你说得对，我自己也算出来了。似乎没有System.Runtime
assembly，所有东西都应该在mcorslib
中可用。只是从文章和源代码中删除了行，所以它更干净了。这听起来像是在使用/NostLib
选项进行csc.你的回答帮助解决了我的问题。谢谢！你不想把它作为一个真实的答案而不是作为问题的一部分来发布吗？我几乎忽略了它…P.S.祝贺你获得2226分；）说得好！我将把它作为一个单独的答案发布。这个答案听起来很有效。你怎么看得出我引用的是PCL，是引用的mscorlib中的publickkey吗？我在问，因为我不是故意引用任何PCL的在我的应用程序中。我真的想引用mscorlib的实际桌面/IIS版本。我发现在添加System.Runtimefacade dll（）时，Roslyn实际上编译了我的代码。太糟糕了，来自该帖子的程序集绑定重定向似乎无法正常工作，因为这是一个错误
