There are usually two different scenarios for using aspNetPOP3, either you are using it from Visual Studio .NET or you aren’t. Below you will find some brief tutorials for using aspNetPOP3 from either of these scenarios.
When you are using aspNetPOP3 in Visual Studio .NET it is recommended you IMPORT the aspNetPOP3.dll to the project. Once inside of the project, then set a reference to the IMPORTED copy, not the GAC copy. We recommend this, because in case aspNetPOP3 is uninstalled from the server, your application will still run off of the imported aspNetPOP3.dll copy.
Please note that licensing requires a purchased license from aspNetPOP3 for each copy installed on a different server or computer. The option of a site license is also available, where aspNetPOP3 can be installed on an unlimited number of systems, at a single, physical (mailing address) location. Please visit www.aspNetPOP3.com for the latest licensing terms.
