Apply a License Key in IronBarcode

The license key is a long string that includes an expiration date, marking the end of support. The license is perpetual, meaning you can continue using it for versions released before this date. Please ensure it is copied correctly, without any spaces.

IRONBARCODE-MYLICENSE-KEY-1EF01-RENEW.SUPPORT.01.JAN.2050

The most robust method of applying a license key is directly in your code before the library is called.

// Apply the IronBarCode license key directly in your code before using the library
IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-1EF01-RENEW.SUPPORT.01.JAN.2050";
// Apply the IronBarCode license key directly in your code before using the library
IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-1EF01-RENEW.SUPPORT.01.JAN.2050";
' Apply the IronBarCode license key directly in your code before using the library
IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-1EF01-RENEW.SUPPORT.01.JAN.2050"
