Remarks

During the wait, the IDE is placed in a modal state to prevent reentrancy. If the wait takes more than 2 seconds, a wait dialog is presented to the user which can be canceled (by default). Callers can use the default behavior, which will show default text in the wait dialog, or they can provide custom values for things like the dialog text, status bar text, timeout values, and so on.

Callers can also provide a custom implementation of IVsCommonMessagePumpClientEvents, which allows the client to run code when certain events occur such as messages being processed, a timeout, or a handle being signaled. This interface can also be used to determine if the wait should continue or return.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
