c# - 我的 Winforms C# 项目设计器被我的 C++/CLI 项目消灭了

Question

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(bind)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 引用的 csproj 片段:

<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.

有什么我想念的吗？此时我可以使用哪些调试策略？

我的 CSPROJECT 需要这个 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。

我猜这是来自堆栈跟踪的 c++/cli 和/或 c# 引用问题:

VSLangProj.Reference.get_Path()

尝试删除您的 c++/cli 和/或 c# 项目中的任何无效引用。 (无效的引用在项目属性中用感叹号图标标记)
