Storage Client Library for Windows Phone (Version 7.0)

Initiates an asynchronous operation to create an empty append blob. If the blob already exists, this operation will overwrite it. To throw an exception if the blob exists, instead of overwriting, pass in an AccessCondition object generated using GenerateIfNotExistsCondition.
