Not Yet Implemented and Known Gaps

Gap	Details
Handle-based image import/load	The C API exposes WslcImportSessionImage and WslcLoadSessionImage from a HANDLE; the WinRT metadata exposes path-based ImportImage / ImportImageAsync and LoadImage / LoadImageAsync.
Explicit container start flags	Container::Start() takes no parameters. In winrt_Container.cpp, the wrapper automatically sets WSLC_CONTAINER_START_FLAG_ATTACH when the init process output mode is Event or Stream.
Raw process callback plumbing	The C API exposes WslcSetProcessSettingsCallbacks, WslcGetProcessExitEvent, and raw I/O handles. The WinRT projection hides that behind ProcessSettings::OutputMode, OutputReceived, ErrorReceived, Exited, GetInputStream, and GetOutputStream.
