Convert XAP to APPX

Understanding XAP and APPX file formats

XAP is a file format used for packaging Silverlight applications. It is essentially a compressed archive containing the application’s DLLs, resources, and other necessary files. XAP files were primarily used for Windows Phone 7 and 8 applications.

APPX is the modern packaging format for Windows applications, introduced with Windows 8. It is used for distributing and installing applications on Windows 8, Windows 10, and later versions. APPX files provide a more secure and efficient way to package and deploy applications, supporting features like app updates and installation on multiple devices.

Converting XAP to APPX

Converting a XAP file to an APPX file involves repackaging the application to meet the requirements of the APPX format. This process may require updating the application code to be compatible with the newer Windows platforms.

Best software for XAP to APPX conversion

The best tool for converting XAP to APPX is the Microsoft Visual Studio. Visual Studio provides a comprehensive development environment that supports the conversion and updating of applications to the APPX format.

To convert a XAP file to APPX using Visual Studio, follow these steps:

• Open Visual Studio and create a new project.
• Import your existing XAP project files into the new project.
• Update the project to be compatible with the Universal Windows Platform (UWP).
• Use the File → Export → APPX option to package the application as an APPX file.

Ensure that all dependencies and resources are updated to be compatible with the APPX format and the target Windows version.
