What is STA in .NET?
Single-threaded apartments or the apartment model process offers a message-based
paradigm for dealing with multiple objects running concurrently. It enables one
to write more efficient code by allowing an awaiting thread to wait for another
time-consuming operation to complete before it can be executed. Each thread in
a process that is initialized as an apartment model process which retrieves and
dispatches window messages, is a STA thread. Every thread lives within its own
apartment. Within an apartment interface pointers can be passed without
marshaling allowing all objects in a STA thread to communicate directly. It
forms a logical grouping of related objects that execute on the same thread and
therefore must have synchronous execution. That’s why the name apartment or
single-threaded apartments.
