This guide covers everything you need to know about implementing your license key, troubleshooting common validation issues, and ensuring your document generation workflows remain uninterrupted. 🛠️ What is Xceed.Words.NET.Licenser.LicenseKey?
By setting this property at the entry point of your application, you unlock the full version of the software, removing: Trial watermarks on generated documents. The "Evaluation Version" pop-ups or text injections. Execution limits or trial expiration locks. 💻 How to Set Your License Key
Since the Xceed.Words.NET.Licenser.LicenseKey is a sensitive asset, avoid hardcoding it directly into your source code if you are working in a public repository (like GitHub). Store it in appsettings.json or Web.config . xceed.words.net.licenser.licensekey
For high-security environments, encrypt the key at rest and decrypt it only during the application startup routine.
using Xceed.Words.NET; namespace MyProject { class Program { static void Program() { // Set your license key here Licenser.LicenseKey = "WDNXX-XXXXX-XXXXX-XXXX"; // Now you can safely use DocX methods using (var document = DocX.Create("HelloWorld.docx")) { document.InsertParagraph("Hello World!"); document.Save(); } } } } Use code with caution. VB.NET Implementation This guide covers everything you need to know
Place the initialization in the constructor of your main app class.
Hidden spaces or newline characters copied from an email can invalidate the key. It is best to paste the key into a plain text editor (like Notepad) first to strip formatting before moving it into your code. 4. Expired Subscription The "Evaluation Version" pop-ups or text injections
Xceed licenses are often version-specific. If you have a license for version 2.0 but are using NuGet to pull version 3.5, your key will be rejected. Check your for the supported version range. Verify the Assembly Version in your project references. 3. Whitespace and Formatting
If you have entered a key but are still seeing trial limitations, check the following common pitfalls: 1. Key Placement
The license key must be set before any other call to the Xceed library is made. The best practice is to place this code in your application's startup logic (e.g., Main method, Global.asax , or App.xaml.cs ). C# Implementation
