Visual Studio 2012

Waits for this task to reach a terminal state. It is possible for wait to execute the task inline, if all of the tasks dependencies are satisfied, and it has not already been picked up for execution by a background worker.

task_status wait() const;

Return Value

A task_status value which could be either completed or canceled. If the task encountered an exception during execution, or an exception was propagated to it from an antecedent task, wait will throw that exception.

Remarks

Important
In a Windows Store app, do not call wait in the body of a continuation that runs on the STA. Otherwise, the runtime throws concurrency::invalid_operation because this method blocks the current thread and can cause the app to become unresponsive. However, you can call the concurrency::task::get method to receive the result of the antecedent task in a task-based continuation.
