Hello, we are using WindowsAppRuntime (indirectly) from an winui3 desktop application. We noticed that the application does not start when calling SetDefaultDllDirectories. I managed to track the issue to this LoadLibraryExW call when calling it with a relative path (dcompi.dll during my tests)
).
The documentation of LoadLibraryExW states about LOAD_WITH_ALTERED_SEARCH_PATH that:
If this value is used and lpFileName specifies a relative path, the behavior is undefined.
A minimally reproducible example of the behavior (without the entire winui infrastructure, just for demonstration purposes):
int main()
{
SetDefaultDllDirectories(LOAD_LIBRARY_SEARCH_DEFAULT_DIRS);
HMODULE mod = LoadLibraryExW(L"dcompi.dll", nullptr, LOAD_WITH_ALTERED_SEARCH_PATH);
return 0;
}
Steps to reproduce the bug
Run any WindowsAppRuntime app that calls SetDefaultDllDirectories. It should just work.
