The annotation entity represents an annotation (note) and contains information that includes: the annotation (note) text, who created and modified the annotation (note), and if a file is attached to the annotation (note).
An attached file can be any standard PC file format, including Microsoft Word documents, Microsoft Excel spreadsheets, CAD files, and PDF files. An attachment can be associated with any object, other than an annotation (note), in the Microsoft Dynamics CRM system.
To upload or remove an attachment, use the Update message, setting the filename and mimetype properties. This uploads an attachment that has been decoded into a base64 string format. The System.Convert.ToBase64String method can be used to convert the contents of a data file into base64 formatted string. There is a maximum file size limit on the uploaded file data. That limit is defined in the system registry. For more information, see maxuploadfilesizeV4d0_SP5700r_maxrecordsforexporttoexcel.
