EPPlus 6 Beta

Announcement: new license model from version 5

EPPlus has from this new major version changed license from LGPL to Polyform Noncommercial 1.0.0.

With the new license EPPlus is still free to use in some cases, but will require a commercial license to be used in a commercial business.

This is explained in more detail here.

Commercial licenses, which includes support, can be purchased at (https://www.epplussoftware.com/).

The source code of EPPlus has moved to a new github repository

LicenseContext parameter must be set

With the license change EPPlus has a new parameter that needs to be configured. If the LicenseContext is not set, EPPlus will throw a LicenseException (only in debug mode).

This is a simple configuration that can be set in a few alternative ways:

1. Via code

// If you are a commercial business and have
// purchased commercial licenses use the static property
// LicenseContext of the ExcelPackage class :
ExcelPackage.LicenseContext = LicenseContext.Commercial;

// If you use EPPlus in a noncommercial context
// according to the Polyform Noncommercial license:
ExcelPackage.LicenseContext = LicenseContext.NonCommercial;
    
using(var package = new ExcelPackage(new FileInfo("MyWorkbook.xlsx")))
{

}

2. Via appSettings.json

{
    {
    "EPPlus": {
        "ExcelPackage": {
            "LicenseContext": "Commercial" //The license context used
            }
        }
    }
}

3. Via app/web.config

<appSettings>
    <!--The license context used-->
    <add key="EPPlus:ExcelPackage.LicenseContext" value="NonCommercial" />
</appSettings>

4. Set the environment variable 'EPPlusLicenseContext'

This might be the easiest way of configuring this. Just as above, set the variable to Commercial or NonCommercial depending on your usage.

Important! The environment variable should be set at the user or process level.
