Property Value

Type: System::Int64

An Int64 representing the total size of the download, in bytes.

For CheckForUpdateProgressChanged, the BytesTotal property refers to the downloading of the deployment manifest. For UpdateProgressChanged, the property refers to the download progress of the entire update, included the manifests, assemblies, and data files. For DownloadFileGroupProgressChanged, the property refers to the download progress of the entire set of files that are part of the named group.
