Create Word (DOCX) or PDF file on Azure
GemBox.Document is a standalone .NET component that's ideal for web applications because of its fast performance and thread safety when working with multiple DocumentModel objects.
GemBox.Document can be used on various platforms including Azure Functions and Azure App Services. To create an Azure function, search for "Azure Functions" in a new project dialog. To avoid any potential issues with GemBox.Document, we recommend using the newer versions of Azure Functions (v3 or above). The following is an Azure function project file: Note that saving to XPS and image formats (like PNG and JPG) currently works only on Azure Functions that target .NET Framework. The following example shows how you can create a Word document using GemBox.Document in an Azure Function. App Service is a fully managed platform for building, deploying and scaling web apps. GemBox.Document can be used from applications that run on an App Service. To build an ASP.NET Core application, check out our ASP.NET Core example. To publish an application to Azure App service you need to: 1. Pick Azure as publish target. 2. Pick Azure App Service as a specific target. 3. Specify existing App Service or create a new one. You can use the full functionality of GemBox.Document on Azure Virtual Machine, Azure Cloud Services, and Azure Functions. But for App Services, there are few rendering limitations: These features currently have WPF dependencies which means they require a .NET Windows Desktop Runtime. However, we do have plans for providing cross-platform support for them in future releases.Azure Functions
