如何将接口方法实现与mono.cecil别名?

我在用 Mono.Cecil (0.6.9.0版)对实现接口方法的方法进行别名。为此,我必须添加一个 Override 指向指向接口方法的目标方法(与vb.net非常类似),如下所示:

using System;
using System.Reflection;
using Mono.Cecil;

class Program {

  static void Main(string[] args) {
    var asm = AssemblyFactory.GetAssembly(Assembly.GetExecutingAssembly().Location);

    var source = asm.MainModule.Types["A"];
    var sourceMethod = source.Methods[0];
    var sourceRef = new MethodReference(
      sourceMethod.Name,
      sourceMethod.DeclaringType,
      sourceMethod.ReturnType.ReturnType,
      sourceMethod.HasThis,
      sourceMethod.ExplicitThis,
      sourceMethod.CallingConvention);

    var target = asm.MainModule.Types["C"];
    var targetMethod = target.Methods[0];
    targetMethod.Name = "AliasedMethod";
    targetMethod.Overrides.Add(sourceRef);

    AssemblyAssert.Verify(asm); // this will just run PEVerify on the changed assembly
  }

}

interface A {
  void Method();
}

class C : A {
  public void Method() { }
}

我得到的是 PEVerify.exe 指示类不再实现接口方法的错误。似乎在更改的程序集中,重写引用和接口中的方法之间存在令牌不匹配:

[MD]: Error: Class implements interface but not method (class:0x02000004; interface:0x02000002; method:0x06000001). [token:0x09000001]

我知道如果我使用 MethodDefinition 直接起作用:

targetMethod.Overrides.Add(sourceMethod);

但我真的需要用 MethodReference 因为我可能在涉及的类型中有泛型参数和参数,并且 方法定义 不行。

更新 :根据建议 Jb Evain 我已经 migrated 到0.9.3.0版。但是,同样的错误仍然会发生。迁移的代码如下:

var module = ModuleDefinition.ReadModule(Assembly.GetExecutingAssembly().Location);

var source = module.GetType("A");
var sourceMethod = source.Methods[0];

var sourceRef = new MethodReference(
  sourceMethod.Name,
  sourceMethod.ReturnType) {
    DeclaringType = sourceMethod.DeclaringType,
    HasThis = sourceMethod.HasThis,
    ExplicitThis = sourceMethod.ExplicitThis,
    CallingConvention = sourceMethod.CallingConvention 
};

var target = module.GetType("C");
var targetMethod = target.Methods[0];
targetMethod.Name = "AliasedMethod";
targetMethod.Overrides.Add(sourceRef);
