从 WPF 窗口中的托管 DLL 启动 WNDProc

我试图让托管 DLL 与我的 WPF 应用程序一起使用时难倒了自己。这个想法是从 WPF MainWindow 的代码后面调用该函数（这样我就可以获取窗口句柄）并传递该函数和另一个指针，该指针最终成为 wchar_t 类型的指针。

我可以调用 dll，但是 WNDProc 无法启动，我认为它与应用程序的实例甚至句柄有关，但我无法将手指放在它上面。项目生成成功，只是没有运行 WNDProc。

该应用程序的想法是使用 WPF 并调用 c++ 来启动一个服务器实例，该实例调用 Windows 中内置的远程协助 API。

这是我所拥有的：

关于为什么 Wndproc 不运行的任何想法或建议？

干杯。
