Set your license using code

Add the following code at the startup of your application, before using IronQR, to set your license key:

:path=/static-assets/qr/content-code-examples/how-to/license-keys-set-license.cs

// Set the license key for IronQR before using the library
IronQr.License.LicenseKey = "IronQR-MYLICENSE-KEY-1EF01";

IRON VB CONVERTER ERROR developers@ironsoftware.com

Set your license using Web.Config or App.Config

To apply a key globally to your application using Web.Config or App.Config, add the following key to your config file in appSettings:

<configuration>
  ...
  <appSettings>
    <!-- Add your IronQR License Key here -->
    <add key="IronQR.LicenseKey" value="IronQR-MYLICENSE-KEY-1EF01"/>
  </appSettings>
  ...
</configuration>

<configuration>
  ...
  <appSettings>
    <!-- Add your IronQR License Key here -->
    <add key="IronQR.LicenseKey" value="IronQR-MYLICENSE-KEY-1EF01"/>
  </appSettings>
  ...
</configuration>

Note: There is a known licensing issue with IronQR versions released before 2024.3.2 on projects:

• ASP.NET projects
• .NET Framework version >= 4.6.2

The key stored in a Web.config file may NOT be picked up and used by the product. Visit the troubleshooting article to learn more.

Ensure that IronQR.License.IsLicensed returns true to verify the license is applied successfully.

Set your license key using a .NET Core appsettings.json file

To apply a key globally to your .NET Core application:

• Add a JSON file to your project called appsettings.json in the root directory.
• Add a IronQR.LicenseKey key to your JSON config file. The value should be your license key.
• Ensure the file property Copy to Output Directory is set to Copy always.

File: appsettings.json

{
    "IronQR.LicenseKey": "IronQR-MYLICENSE-KEY-1EF01"
}
