Calling the COM-API directly via P/Invoke

Why isn't it possible to call the COM-API (CoInitialize,
CoCreateInstance, etc.) directly via P/Invoke instead of writing a
unmanaged+managed wrapper or using a library like CFCOM?

Which DLL exports the COM functions?

Sorry I'm a newbe with COM Interop.
 
CoCreateInstance will only create you an instance of a COM interface, you
can call this function from managed code, the problem then is that there is
no way to directly invoke functions on the object, which is why its
necessary to provide an interop layer in native code to expose standard C
functions to call these COM methods.
..NETCF v2.0 will support calling COM code directly from your managed code by
producing a runtime callable wrapper around a COM interface, as you can do
with the desktop .NET v1.x framework.
