c# - 如何配置 Roslyn CustomWorkSpace 不为 Visual Basic 而哭泣？

Question

我有一个简单的 Roslyn 代码行如下:

var workspace = new CustomWorkspace();

此行抛出(并在内部处理)如下异常:

"Could not load file or assembly 'Microsoft.CodeAnalysis.VisualBasic.Workspaces, Version=0.6.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified."

请注意，仅当您在调试器中运行代码并配置 VS 以不仅显示未处理的异常时，异常才可见。

我根本不想使用 Visual Basic 的功能。我已经查看了 Workspace 构造函数重载，最有前途的是接受 FeauterPack 的重载，但不幸的是

 public class CSharpWorkspaceFeatures : FeaturePack

当前不存在(并且在当前 Roslyn 源代码中也被完全注释掉)

我错过了什么吗？

提前致谢

E D I T:对于@SLaks:(我没有使用 Roslyn 源代码运行，只是使用 NuGet 包。所以这是我拥有的所有异常信息:

Answer 1

在//build/2014 期间发布的当前预览版中，您需要执行以下操作:

var customWorkspace = new CustomWorkspace(new MefExportPack(catalog));

目录是 MEF 目录。您可以看到一些代码来构建目录 here .

自那次预览以来，我们已经 renamed a bunch of the types .如果您来自 future (欢迎过去的我!)并使用包含该更改的预览，请改为尝试此操作:

var customWorkspace = new CustomWorkspace(MefHostServices.Create(assemblies));

其中 assemblies 是您希望我们包含在 MEF 组合中的程序集的列表。您可以Assembly.Load 您关心的那些，在本例中为 Microsoft.CodeAnalysis.Workspaces.dll 和 Microsoft.CodeAnalysis.CSharp.Workspaces.dll。您可能还需要包括功能 DLL，具体取决于您正在做什么。
