In your build pipeline, include a step that verifies the license key does not expire during your test suite.
Install-Package Xceed.Words.NET
The NuGet package includes a trial key for initial testing.
If budget is the constraint, replacing the library with an open-source alternative is often superior to using a pirated version of Xceed. Open source is free to use legally and often supported by a large community.

If your goal is "high quality" output and stable software, the following approaches are recommended over searching for unauthorized keys.
In scenarios where configuration files are not desirable, the key can be set directly in the code. This must be executed at the very start of the application (e.g., in the Main method or Application_Start event).
C# Code Example:
using Xceed.Words.NET;
namespace DocumentAutomation
class Program
static void Main(string[] args)
// Set the license key before calling any other Xceed methods
Xceed.Words.NET.License.LicenseKey = "YOUR_LICENSE_KEY_STRING_HERE";
// Proceed with document creation
using (var document = DocX.Create("Report.docx"))
document.InsertParagraph("Hello, Licensed World!");
document.Save();
To ensure high-quality performance and avoid runtime errors, the license key must be set before any document operations are performed. The standard implementation involves adding the key to your configuration file or setting it directly in code.
This is where most confusion happens. You do not need an external license file. Instead, you set the key at application startup.
using Xceed.Words.NET;// High-quality license key validation Licenser.LicenseKey = "YOUR-PURCHASED-KEY-HERE"; xceedwordsnetlicenserlicensekey high quality
// Now use any feature without limitations using (DocX document = DocX.Create("output.docx")) document.InsertParagraph("Hello, licensed world!"); document.Save();
Important: Store the key in a secure configuration (e.g., environment variable, Azure Key Vault, or encrypted appsettings.json). Never hardcode it in client-side code if distributing a desktop app—use obfuscation or server-side validation. In your build pipeline, include a step that
