使用Roslyn.Services.Workspace进行单元测试会导致在x86目标下工作时出现SecurityException

标签： nunit deserialization appdomain roslyn ncrunch

我正在处理我的项目的常量集，我想使用来验证源代码级别中的一些常量。为实现这一目标，我将使用以下代码段将整个解决方案加载到AppDomain with IsFullyTrusted == true and IsHomogenous == true, i.e. remoting is enabled with x86 platform target：

// load workspace, i.e. solution from Visual Studio
var workspace = Roslyn.Services.Workspace.LoadSolution(solutionFile);

使用带有Roslyn

的x86平台测试NCrunch和NUnit的跑步者

但同时使用 1.45或 2.6.2 nunit-console-x86.exe并将平台配置x86作为测试运行者时，我会不断关注System.Security.SecurityException < /强>：

System.Security.SecurityException : Type System.Runtime.Remoting.ObjRef and the types derived from it (such as System.Runtime.Remoting.ObjRef) are not permitted to be deserialized at this security level.

有a discussion on NCrunch forum，但我已尝试以下所有选项但未成功：

  • 将[assembly: AllowPartiallyTrustedCallers]添加到AssemblyInfo.cs
  • 将[assembly: SecurityRules(SecurityRuleSet.Level1)]添加到AssemblyInfo.cs
  • 将<NetFx40_LegacySecurityPolicy enabled="true" />添加到a​​pp.config
  • 以管理员身份运行VS2012
  • 使用[SecuritySafeCritical]
    • 装饰单元测试和实现
  • 更新：创建新AppDomain并提供
    • PermissionState.Unrestricted，SecurityPermissionFlag.AllFlags和DataProtectionPermissionFlags.AllFlags
    • 添加主机证据：SecurityZone.MyComputer，System.Security.Policy.Hash和System.Security.Policy.StrongName
    • 创建fullTrustAssemblies
      • 时，将所有程序集（我的和Roslyn CTP）添加到AppDomain

更新＃2

只有当我在x86配置下运行测试时才会发生此异常，在我切换到x64平台配置后，一切似乎都正常工作

问题

app.config或AppDomain是否有任何其他属性或配置更改可能有助于在x86配置下运行时在System.Runtime.Remoting.ObjRef的.NET Framework远程处理中启用反序列化？

临时解决方案

仅针对unittest项目切换到x64构建配置

源代码

其他信息

我也注意到了......

  1. 在所有测试完成后，很多Roslyn.Services.dll实例都在后台挂起。
  2. NCrunch缺乏主机证据：System.Security.Policy.Hash和System.Security.Policy.StrongName带有测试运行器程序集名称
  3. MSIL（应该是x64内部）和 2.6.2 nunit-console.exe测试运行器工作正常，所以它看起来像Roslyn配置/远程处理/安全配置问题即可。

2 个答案:

答案 0 :(得分：4)

看起来正在部分信任中执行测试，而Resharper正在完全信任中运行它们。

Roslyn尚未在部分信任方案中进行测试。可能会访问需要完全信任的API。

我没有使用ncrunch，但也许有一种方法可以配置它以完全信任的方式运行测试？

答案 1 :(得分：1)

我想添加一些内容！

升级NUnit实例后，我设法运行到软件的2.6.2和2.6.3，我的团队遇到了Akim看到的确切System.Security异常的类似问题。

我们正在创建一个IpcChannel，其中包含一些我们自定义的NUnit逻辑，这些逻辑并非使用正确的信任设置创建，因此我们不得不更改类似的内容：

IpcChannel channel = new IpcChannel(string.Format("localhost:{0}", portNum));

到 - 

BinaryServerFormatterSinkProvider serverProvider = new BinaryServerFormatterSinkProvider();
serverProvider.TypeFilterLevel = System.Runtime.Serialization.Formatters.TypeFilterLevel.Full;

BinaryClientFormatterSinkProvider clientProvider = new BinaryClientFormatterSinkProvider();

var properties = new System.Collections.Hashtable();
properties["name"] = "ipc";
properties["priority"] = "20";
properties["portName"] = string.Format("localhost:{0}", portNum);

IpcChannel channel = new IpcChannel(properties, clientProvider, serverProvider);

只是一个快速修复我注意到我想我会转发任何人看到类似的东西，不能只是切换他们的平台设置。公平地说，我花了大约四个小时来弄清楚所以我不想让这些知识浪费掉。
