ABSTRACT:
A computer-based method and system for accessing objects of different thread types in a single process. The system provides single-threaded apartments (STAs) for loading apartment-threaded objects and a multi-threaded apartment (MTA) for loading free-threaded objects. Each STA has a single thread, and the MTA has multiple threads. When an STA thread requests to access a free-threaded object, the system creates an MTA thread and requests the MTA thread to instantiate the free-threaded object. The STA thread then receives a marshalled pointer to the free-threaded object and unmarshals the received pointer. The STA thread then accesses the free-threaded object using the unmarshalled pointer so that the MTA thread accesses the free-threaded object on behalf of the STA thread. When an MTA thread requests access to an apartment-threaded object, the system creates an STA thread and requests the STA thread to instantiate the apartment-threaded object. The MTA thread then receives a marshalled pointer to the apartment threaded object and unmarshals the received pointer. The MTA thread then accesses the apartment-threaded object using the unmarshalled pointer so that the STA thread accesses the apartment-threaded object on behalf of the MTA thread.
