InvalidOperationException：动态操作只能在同源AppDomain中执行 [英] InvalidOperationException: Dynamic operations can only be performed in homogenous AppDomain

问题描述

我在使用moles和DLR同时引发此异常时遇到问题：InvalidOperationException：动态操作只能在同类AppDomain中执行

I have an issue when using moles and the DLR at the same time that causes this exception to be thrown: InvalidOperationException: Dynamic operations can only be performed in homogenous AppDomain

我猜它正在抛出，因为Moles测试主机不会创建一个同质的AppDomain。导致异常的代码可以在下面找到。

I guess it's throwing because the Moles test host doesn't create a homogenous AppDomain. The code that will cause the exception can be found below.

using System.IO; 
using System.IO.Moles; 
using Microsoft.VisualStudio.TestTools.UnitTesting; 

[TestClass] 
public classFileWrapperTest 
{ 
 [TestMethod, HostType("Moles")] 
 publicvoid TestMethod1() 
 { 
  // arrange 
  var fileWrapper = new FileWrapper(); 
  MFile.ExistsString = path => false; 

  // act
  dynamic exists = fileWrapper.DoesExist(@"C:\temp\test.txt"); 

  // assert
  Assert.IsFalse(exists); 
 } 

 public classFileWrapper 
 { 
  public bool DoesExist(string path) 
  { 
   return File.Exists(path); 
  } 
 } 
}
