BE0075: For MS Help Viewer builds, the HtmlHelpName property cannot contain periods

Error BE0075: For MS Help Viewer builds, the HtmlHelpName property cannot contain periods, ampersands, or pound signs as they are not valid in the help file name.

This error occurs if there are periods, ampersands, or pound signs in the HtmlHelpName project property value.

The HtmlHelpName value is used as the MS Help Viewer help file name when building an MS Help Viewer file. Periods, ampersands, and pound signs are not valid in MS Help Viewer filenames apart from the period used to separate the filename and the extension and must be removed from the property value.
