If you purchase a license key, it is valid for all versions released up to one year after the purchase date. If you upgrade your NuGet package to a version of GemBox.Document released after your maintenance period expired, your key will be rejected. You will need to either downgrade the package to a supported version or renew your license. Multi-threaded SetLicense Calls
Tied to an individual software developer. It allows the developer to use GemBox on any number of machines, provided they are the sole user.
The is a simple configuration string that unlocks full, enterprise-grade document manipulation capabilities in your .NET applications. By inserting your legitimate serial key into the application startup sequence, you eliminate free-tier thresholds and ensure smooth document conversions.
GemBox.Document offers three primary modes based on the key provided: : Use the key "FREE-LIMITED-KEY" Gembox.document License Key
Unlike some software that requires complex license servers or online activation, GemBox uses a simple, offline programmatic activation method. The key is embedded directly into your source code, making it highly compatible with modern CI/CD pipelines, cloud deployments (Azure, AWS), and containerized environments (Docker). 2. Free Mode vs. Professional Mode
Applying the license key in your .NET application is straightforward. You must execute the activation code before calling any other GemBox.Document methods or classes. The standard practice is to place this code in the application startup routine (e.g., Main method, Global.asax , Startup.cs , or Program.cs ). C# Code Example
: Free mode is limited to 20 paragraphs and 5 tables per document. If you purchase a license key, it is
// Set license key to use GemBox.Document in Free mode ComponentInfo.SetLicense("FREE-LIMITED-KEY");
class Program
GemBox.Document is a popular, high-performance .NET component that enables developers to read, write, convert, and print document files (DOCX, DOC, PDF, HTML, XPS, and RTF) without requiring Microsoft Word. It is widely used in enterprise environments to automate document processing. By inserting your legitimate serial key into the
using System; using GemBox.Document; class Program static void Main(string[] args) // Set your commercial license key here ComponentInfo.SetLicense("YOUR-GEMBOX-DOCUMENT-COMMERCIAL-KEY"); // Your document processing code follows DocumentModel document = new DocumentModel(); document.Content.Blocks.Add(new Paragraph(document, "Hello World!")); document.Save("Output.docx"); Use code with caution. 2. ASP.NET Core Web Applications
// Replace with your purchased serial key ComponentInfo.SetLicense("XXXX-XXXX-XXXX-XXXX");
Activating a license is a simple one-line method call before using any other classes from the GemBox.Document assembly.
