task_continuation_context::use_default Method


Creates the default task continuation context.

static task_continuation_context use_default();

The default continuation context.

The default context is used if you don't specifiy a continuation context when you call the then method. In Windows applications for Windows 7 and below, as well as desktop applications on Windows 8 and higher, the runtime determines where task continuations will execute. However, in a Windows Store app, the default continuation context for a continuation on an apartment aware task is the apartment where then is invoked.

An apartment aware task is a task that unwraps a Windows Runtime IAsyncInfo interface, or a task that is descended from such a task. Therefore, if you schedule a continuation on an apartment aware task in a Windows Runtime STA, the continuation will execute in that STA.

A continuation on a non-apartment aware task will execute in a context the Runtime chooses.
