Create Google API - GMail Parser

We are looking for a simple Gmail parser class that we can use to download messages in a readable format. The class must do the following: 1. Log in to a single Gmail account (Provided Username/Password and any API keys required) 2. Download all messages after a specific date or message id in the following format: - string From - string To - DateTime ReceivedOn (UTC or local time) - string Subject - string HTMLBody - string TextBody - List<string> AttachmentNames - string MessageID - The ID provided by Google - string TicketID - TicketID will be parsed from the subject and/or body if it exists (Regex Match) 3. Either maintain a connection and be notified of new messages OR disconnect and we will run the process again after a minute or two Finally, attachments can be downloaded from the message using the following method: byte[] GetFileAttachment(string attachmentname) Additional Requirements / Information: - We will only be receiving messages through this API and NOT sending. - You will be reporting to a senior developer. - Project is due ASAP - All source code / Intellectual property will belong to us - Google API must be used - 3rd Party components are not allowed unless explicitly approved by the project manager
