Apply a license key in IronBarcode
The license key is a long string that ends with an expiry date. Please ensure this is copied correctly, with no spaces.
The most robust method of applying a license key is directly in your code, before the library is called.
IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-RENEW.SUPPORT.01.JAN.2050";
