我正在开发一个AutoCAD插件，并且我正在使用PostSharp onMethodBoundaryAspect在插件引入每个命令之前执行一些任务。我已经使用属性声明了方面。
[PSerializable]
[MulticastAttributeUsage(MulticastTargets.Method, TargetMemberAttributes = MulticastAttributes.Public)]
public class OnCommandBoundaryAspect : OnMethodBoundaryAspect {
...
}
，然后在命令类中
[OnCommandBoundaryAspect]
public class AnnotationCommands {
[CommandMethod("MY_ACAD_COMMAND")]
public void MyCommand() {
doStuff();
}
}
在针对普通Acad DLL（带有普通的AutoCAD安装的DLL）编译插件时，一切正常。我们还拥有包括插件的AutoCAD OEM产品。现在，当使用AutoCAD OEM DLL编译插件时，我得到 PostSharp.sdk.CodeModel.BindingException ，请参阅stack

我已经知道，与AutoCAD安装程序的DLL相比，AutoCAD OEM DLL受到某种方式受到限制。
发生了什么事？为什么后肖普试图反映项目中的引用DLL？有任何建议如何解决问题？
如果GAC中存在组件并且在构建之前尚未删除，也可能会出现此问题。诸如方法签名更改之类的重大变化可以与后莎普目标拧紧，因为它希望从您的来源中找到一个签名，并在GAC中找到不同的签名。
从您的GAC文件夹中删除组件以帮助消除此原因。
好吧，我应该知道这一点，但是我们在命令类中也有一些lispfunctions， lispfunctionAttribute type type在AutoCAD OEM DLL中都不可用。<</
[LispFunction("GetProperties")]
public static ResultBuffer GetProperties(ResultBuffer args) {
....
}
排除后期方法的方法解决了问题。
如果可能的话，可以在异常中显示类型名称
