Upgrade to Latest Version

In This Topic

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

Open an existing application created using DsPdf license.
Right-click the project in Solution Explorer and choose Manage NuGet Packages.
In the Package source on top right, select nuget.org.
Click Updates tab on the top. A list of all the installed NuGet packages is displayed.
On the left panel, select the Select all packages checkbox and click Update.
In the Preview Changes dialog, click OK and choose I Accept in the next screen.
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");
```

Note: With v7.0, GrapeCity.Documents.Pdf (GcPdf) package is renamed to DS.Documents.Pdf (DsPdf). The namespaces and classes within DS.Documents.Pdf remain the same, which provide the same functionality and are backwards compatible with GrapeCity.Documents.Pdf, ensuring minimal impact on your existing projects.

To upgrade GcPdf package to DsPdf package in your existing projects, follow one of the below options:

Update package using Migration tool:
1. The migration tool is present in the package downloaded from the website. Follow the instructions displayed in the UI when using the tool for a seamless migration from GcPdf to DsPdf.
Update package manually from NuGet package manager:
1. In Solution Explorer, right-click either Dependencies or a project and select Manage NuGet Packages.
2. In Installed tab, click on GrapeCity.Documents.Pdf package and click Uninstall to remove it and its dependencies from the project.
3. In Browse tab, type "ds.documents" or "DS.Documents" in the search text box at the top and find the package "DS.Documents.Pdf".
4. Click Install to add the DS.Documents.Pdf package and its dependencies to the project.
