Briefly explain about the different types of threading models n Vb.net?

There are different types of threading models that are available, let us look into the Threading models that are common to win32 based environments.

SingleThreaded: It includes only one thread within the process, and it is responsible for performing all the work for the process. The process must be patient to wait for the completion of the current execution of the thread before it can start performing another action.

Apartment Threading (Single Threaded Apartment): Apartment threading includes multiple threads within the application. In a single-threaded apartment (STA), each thread is associated in a separate apartment under the process. The process can have various numbers of apartments that are capable of sharing the data through a proxy. The application will be defining when and for how long the thread in each apartment should perform the execution. All the requests will be serialized through the Windows message queue such that only a single apartment is allowed to be accessed at a time and thus only a single thread will be executed at any one time.

Free Threading (Multi-Threaded Apartment): Free threaded applications are specifically limited to the different programming languages such as C++ until the release of Microsoft .NET. The free threaded/Multi-Threaded Apartment (MTA) model has a single apartment created under a process rather than multiple apartments. This single apartment is responsible for holding multiple threads rather than just a single thread. There is no requirement of a message queue because all of the threads are a part of the same apartment and are allowed to share data without any proxy.

The developer must ensure that thread synchronization as part of the coding to make sure that the threads will not simultaneously access the same resources.
