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>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.jsonin the root directory. - Add a
IronQR.LicenseKeykey 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"
}Step 3: Test your key
Test if your key has been installed correctly using the following code:
// Validate the license key
bool result = IronQr.License.IsValidLicense("IronQR-MYLICENSE-KEY-1EF01");
// Check if IronQR is licensed successfully
bool isLicensed = IronQr.License.IsLicensed;' Validate the license key
Dim result As Boolean = IronQr.License.IsValidLicense("IronQR-MYLICENSE-KEY-1EF01")
' Check if IronQR is licensed successfully
