请帮我解决这个问题,我一直在使用 AsyncCtpLibrary 和 C#5 ctp 编译器编写控制台应用程序。我第一次实际运行等待的代码时,我得到了这个:
System.BadImageFormatException was unhandled
Message=An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
Source=AsyncCtpLibrary
StackTrace:

InnerException:
我是否缺少要引用的 dll?
重要的新东西
我的失败方法如下所示:
public async override Task<bool> Execute()
{
//do stuff
await stuff;
//do other stuff
await base.Execute()
//do other stuff
return true;
}
我遵循 Jon Skeet 的建议,试图一点一点地重现错误,现在我可以说 await base.Execute() 行是杀手!如果我注释掉那条线,一切都会运行,如果我把它留在里面,调用我的方法会立即失败(不是在到达 base.Execute() 时)。所以我假设 ctp 编译器做了一些奇怪的事情。为什么?我永远不应该做什么?虫子有多大?
老东西:
编辑:
至于 32 位/64 位问题,我的系统是 32 位(在虚拟机内,请注意),据我所知 AsyncCtpLibrary.dll 不包含非托管代码。我所有的项目(类库和单个控制台应用程序)都有这样的构建选项卡:
还有什么可能是错误的?
编辑:我还检查了Fusion 日志查看器,加载 AsyncCtpLibrary 时没有任何错误:

我还检查了编译器生成的类的 MoveNext() 方法的IL 代码<Execute>d__1c
,它引用的唯一程序集 ([assemblyName]) 是 mscorlib、System.Core 和 AsyncCtpLibrary。
我检查了我的 dll 和 AsyncCtpLibrary的清单.corflags 0x00000003 // ILONLY 32BITREQUIRED
,我说,AsyncCtpLibrary 说.corflags 0x00000009 // ILONLY
,我不确定这是否是问题所在。
请帮忙,我没有想法!
