There is a known licensing issue with IronQR version released before 2024.3.2 on project:

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

The key stored in a Web.config file is NOT being picked up and used by the product. Visit the 'Setting License Key in Web.config' troubleshooting article to learn more.

Ensure that IronQR.License.IsLicensed returns true to verify.

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

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

  • Add a JSON file to your project called appsettings.json in the root directory of your project
  • Add a IronQR.LicenseKey key to your JSON config file. The value should be your license key.
  • Ensure that the file properties include Copy to Output Directory: Copy always

File: appsettings.json

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

Step 3: Test your key

Test if your key has been installed correctly.

bool result = IronQR.License.IsValidLicense("IronQR-MYLICENSE-KEY-1EF01");

// Check if IronQR is licensed successfully 
bool is_licensed = IronQR.License.IsLicensed;
bool result = IronQR.License.IsValidLicense("IronQR-MYLICENSE-KEY-1EF01");

// Check if IronQR is licensed successfully 
bool is_licensed = IronQR.License.IsLicensed;
Dim result As Boolean = IronQR.License.IsValidLicense("IronQR-MYLICENSE-KEY-1EF01")

' Check if IronQR is licensed successfully 
Dim is_licensed As Boolean = IronQR.License.IsLicensed
