multi thread DLL will run in the thread that creates the object Different threads of a multithreaded application can thus each have DLL objects running in them quite independantly of any other DLL objects that may be running in other threads DLL objects of a
When that happens NET calls the underlying CoInitializeEx function which takes a flag indicating whether to join the thread to a multi threaded or single threaded apartment A multi threaded apartment MTA in COM is more efficient since any of a number of RPC threads from a pool can be used to handle a request

Multi threaded Apartments Multiple threads in a single free threaded apartment use COM and calls to COM objects are synchronized by the objects themselves A description of communication between single threaded apartments and multi threaded apartments within the same process is in Section Section 6 4
2020 8 21 nbsp 0183 32 While multiple objects can live on a single thread no apartment model object can live on more than one thread Each thread of a client process or out of process server must call CoInitialize or call CoInitializeEx and specify COINIT APARTMENTTHREADED for the dwCoInit parameter The main apartment is the thread that calls CoInitializeEx first

2021 12 7 nbsp 0183 32 No MTA is a property of a single thread just like STA You now make the exact opposite promise you declare that the thread does absolutely nothing to keep external code thread safe So no need to have a dispatcher and you can block as much and as long as you like This has consequences of course and they can be quite unpleasant
