Build an event, that is usable from a C# program, which belongs to a C++ program.

I have a small C++ dll which creates a CLRCreateInstance and loads a C# dll. Here is the source: /////////////////////////////////////////////////////////////////////////////////////////////////////// #include <metahost.h> #pragma comment(lib, "[login to view URL]") DWORD WINAPI ControlThread(LPVOID lpParam) { ICLRMetaHost* metaHost = NULL; ICLRRuntimeInfo* runtimeInfo = NULL; ICLRRuntimeHost* runtimeHost = NULL; if (CLRCreateInstance(CLSID_CLRMetaHost, IID_ICLRMetaHost, (LPVOID*)&metaHost) == S_OK) if (metaHost->GetRuntime(L"v4.0.30319", IID_ICLRRuntimeInfo, (LPVOID*)&runtimeInfo) == S_OK) if (runtimeInfo->GetInterface(CLSID_CLRRuntimeHost, IID_ICLRRuntimeHost, (LPVOID*)&runtimeHost) == S_OK) if (runtimeHost->Start() == S_OK) { DWORD pReturnValue; runtimeHost->ExecuteInDefaultAppDomain(L"C:\\[login to view URL]", L"[login to view URL]", L"EntryPoint", L"asd", &pReturnValue); runtimeInfo->Release(); metaHost->Release(); runtimeHost->Release(); } return 0; } BOOL APIENTRY DllMain(HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { switch (ul_reason_for_call) { case DLL_PROCESS_ATTACH: CreateThread(NULL, NULL, (LPTHREAD_START_ROUTINE)ControlThread, hModule, NULL, NULL); break; case DLL_THREAD_ATTACH: case DLL_THREAD_DETACH: case DLL_PROCESS_DETACH: break; } return TRUE; } /////////////////////////////////////////////////////////////////////////////////////////////////////// And now here is the source code for the C# [login to view URL] /////////////////////////////////////////////////////////////////////////////////////////////////////// namespace ExampleProject { public class Example { public static int EntryPoint(string pwzArgument) { string processName = [login to view URL]().ProcessName; [login to view URL]("The current process is " + processName); return 0; } } } /////////////////////////////////////////////////////////////////////////////////////////////////////// What I want is to create a second thread in the C++ project and call it TickEvent /////////////////////////////////////////////////////////////////////////////////////////////////////// DWORD WINAPI TickEvent(LPVOID lpParam) { while (true) { Sleep(500); //[login to view URL](); } } /////////////////////////////////////////////////////////////////////////////////////////////////////// And use it like this in the C# [login to view URL] /////////////////////////////////////////////////////////////////////////////////////////////////////// namespace ExampleProject { public class Example { public static int EntryPoint(string pwzArgument) { [login to view URL] += OnTick; } private static void OnTick(EventArgs args) { string processName = [login to view URL]().ProcessName; [login to view URL]("Called every 500ms inside " + processName); return 0; } } } /////////////////////////////////////////////////////////////////////////////////////////////////////// The question from me is, can you make an event like this, which is controlled from the C++ dll and usable from any C# dll? If you can complete this task, I will be asking from you to also implement different C++ API which are usable in C# inside the events earlier created. Please take a moment and use the passw0rd "I am C# pr0grammer" to confirm you have read my post in general and are sure you can complete it.
