MEF部分的依赖性

Question

I have a problem regarding MEF. In essence:

assembly my.main {
  class Main {
    <Import>
    Lazy<IMyType> prop;

    public static void Main(...) {
      ComposeParts(this);
      prop.DoStuff();
    }
  }
}

assembly my.interfaces {
  interface IMyType {
    void DoStuff();
  }
}

assembly my.parts {
  using 3rdParty;
  <Export>
  class MyType : IMyType {
    void DoStuff() {
      3rdParty.DoStuff();
    }
  }
}

Both my.main and my.parts reference my.interfaces assembly. In addition to that, my.parts assembly references a 3rd party .dll, which my other two do not. When I try to execute the above, a CompositionException is thrown in Main() when calling prop.DoStuff() with the message saying the class 3rdParty could not be found.

In other words, MEF part is injected, but the dll it requires is not injected/copied.

Does anyone know a solution or workaround to this problem?

Answer 1

在执行期间，显然3rdParty程序集文件与my.parts程序集不在同一目录中（或装入程序探查的任何其他位置）。
