Small and easy to use framework for .NET to manage contact data of organizations and natural persons, including a data model and classes to persist it as vCard (*.vcf) or CSV.
IMPORTANT: On some systems the content of the CHM file is blocked. Before opening the file right click on the file icon, select Properties, and check the "Allow" checkbox - if it is present - in the lower right corner of the General tab in the Properties dialog.
(For the sake of better readability exception handling is ommitted in the following examples.)
