我正在为我的项目处理一组常量，我想使用 roslyn在源代码级别验证其中一些。为了实现这一点，我正在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 中:
// load workspace, i.e. solution from Visual Studio
var workspace = Roslyn.Services.Workspace.LoadSolution(solutionFile);
带有 Roslyn 的 x86 平台的 NCrunch 和 NUnit 测试运行器
但是 同时使用 ncrunch 1.45 或 nunit 2.6.2
nunit-console-x86.exe使用平台配置 x86 作为测试运行器，我不断关注 System.Security.SecurityException :
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 ，但我尝试了以下所有选项都没有成功:
[assembly: AllowPartiallyTrustedCallers]到 AssemblyInfo.cs [assembly: SecurityRules(SecurityRuleSet.Level1)]到 AssemblyInfo.cs <NetFx40_LegacySecurityPolicy enabled="true" />到 app.config [SecuritySafeCritical] 装饰单元测试和实现AppDomain并提供PermissionState.Unrestricted , SecurityPermissionFlag.AllFlags和 DataProtectionPermissionFlags.AllFlags SecurityZone.MyComputer , System.Security.Policy.Hash和 System.Security.Policy.StrongName fullTrustAssemblies在创建 AppDomain 时更新 #2
此异常仅在我在 x86 配置下运行测试时发生，在我切换到 x64 平台配置后，一切似乎都正常
题
app.config 是否有任何其他属性或配置更改？或
AppDomain这可能有助于在 .NET Framework 远程处理中启用反序列化
System.Runtime.Remoting.ObjRef在 x86 配置下运行时？
临时解决方案
仅为单元测试项目切换到 x64 构建配置
源代码
IntrospectionTests.Introspection_SearchForComplexityGt10_ApprovedList 在单元测试之后重现错误运行附加信息
我也注意到...
Roslyn.Services.dll的大量实例在所有测试完成后卡在后台。 System.Security.Policy.Hash和 System.Security.Policy.StrongName带有测试运行程序组件名称 nunit-console.exe测试运行器工作正常，所以看起来像 Roslyn 配置/远程处理/安全配置问题 . 请您参考如下方法:
它看起来像 ncrunch在部分信任中执行测试，而 Resharper 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。
我没有使用过 ncrunch，但也许有一种方法可以将它配置为在完全信任中运行测试？
