【问题描述】：
在过去的几年里，我有很多使用 C++/CLI 的经验，如果我知道一件事，那就是混合模式 DLL 不利于设计。
我有一个 CSPROJECT 项目，它依赖于 CPPPROJECT（使用项目引用，copylocal=true，versionspecific=false，copylocalsattelitedpeendances=false）。
每当我尝试从 CSPROJECT 打开表单或用户控件时，我都会得到：system.exception 被抛出。
我试过 fuslogvw，它不会将任何故障绑定到磁盘。我尝试打开第二个 devenv 进行调试，但它只是在设计器在其调用堆栈中显示的同一位置中断。这是我的 CPPPROJECT 参考的 csproj sn-p：
<ProjectReference Include="..\dfResultsStructures\dfResultsStructures.csproj">
<Project>{D93C5625-0EB1-4645-95C8-F389758521EE}</Project>
<Name>dfResultsStructures</Name>
<Private>False</Private>
<SpecificVersion>False</SpecificVersion>
</ProjectReference>
下面是调用栈
Exception of type 'System.Exception' was thrown.

我有什么遗漏吗？此时我可以使用哪些调试策略？
我的 CSPROJECT 需要此 CPPProject 项目。如果我删除 CPPProject，我的应用程序会设计，但不会编译。我不想每次修改表单时都必须删除引用。

您是否尝试添加对您的 c++/CLI 项目的预编译 dll 的引用？此外，为了使其正常工作，您需要托管 c++ 方法签名以从 C# 代码调用，否则您必须创建一个包装器，在非 CLR c++ 本机代码上执行 DLL 导入。
