Classes

AccountPickerOptions	Represents the options used to create an account picker.

BlockingTaskEventArgs	Event argument to be used with event that passes in blocking task information. The parameters identify the task that is being waited on UI thread (blocked task) and task that is blocking the wait (blocking task).
BulkFileOperation	BulkFileOperation provides functionality to safely perform operations with bulk of files, currently opened in the solution. One of the example is SCC. Before operation consumer should provide estimated set of files and folders where changes are expected. This class takes care about "hands-off" logic for all these files. Once operation done BulkFileOperation does all neccessary job for "hands-on" logic and make a decision on what to reload (project/solution/nothing). Order of operations is the following: QueryBulkFileOperationAsync BeginAsync (optional) EndAsync (optional, but BeginAsync is required to complete before this) Dispose This API is very strict to inappropriate usage, for example calling EndAsync without waiting for BeginAsync is done, or calling the same method twice and so on. In this case exception will be thrown.

During the wait the IDE will be placed in a modal state to prevent reentrancy. If the wait takes more than 2 secs a wait dialog is presented to the user which can be canceled (by default). Callers can call the default behaviour 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 etc. 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, timeout or a handle being signaled. This interface can also be used to detemine if the wait should continue or return.

ThreadHelper	Provide a generic dispatcher helper ensure that a method is invoked on the Application's main thread. We use the current Application's Dispatcher for convenient identification of the main thread. Note that this means that the Application's instance must be initialized. Currently, the WindowManager initializes it. However, we don't use DispatcherOperation because they are not RPC friendly. For example, if the UI thread is in the middle of an RPC call, and we need to run code on the UI thread, then DispatcherOperations will not get through. This is because DispatcherOperations are initiated by posting a message to the UI thread and the UI thread needs to dispatch that message. If the UI thread is making an RPC call, these messages will not be removed from the queue. The standard OLE message filter processes only a limited set of messages from the queue and even the Visual Studio message filter ignores most others. By going through the UIThreadInvokerPrivate service, the operation becomes a COM call on the UI thread. This operation will be allowed through our message filter IF it is part of the same logical call - the message filter will see it as a "nested call" and may not reject it.
