Upgrade to Latest Version

To upgrade a GcPdf license from a previous major version to the current major version, you will need to obtain a new license key from the GrapeCity Sales team. Once you have received a new license key through email, follow these steps:

1. Open an existing application created using GcPdf license.

2. Right-click the project in Solution Explorer and choose Manage NuGet Packages.

3. In the Package source on top right, select nuget.org.

4. Click Updates tab on the top. A list of all the installed NuGet packages is displayed.

5. On the left panel, select the Select all packages checkbox and click Update.

6. In the Preview Changes dialog, click OK and choose I Accept in the next screen.

7. Switch to the code view and replace the old key with new key received through email.

   • To upgrade the license of a particular instance:

     var doc = new GcPdfDocument("new key")

   • To upgrade the license of all the instances:

     GcPdfDocument.SetLicenseKey("new key");
