Developing a VSTO Office add-in can be a rewarding experience, but reaching a wider audience often involves publishing it on the Microsoft Store. This guide provides a step-by-step process to help you navigate the publishing process, ensuring your add-in is ready for the world.
The Problem: Reaching a wider audience
You've built an incredible VSTO Office add-in, offering valuable features and functionality to users. But how do you make it accessible beyond your immediate network? Publishing it on the Microsoft Store opens doors to a vast audience of Office users, increasing discoverability and potential adoption.
The Scenario: Publishing Your Add-in
Imagine you've developed a VSTO add-in for Excel that automates data analysis tasks. You're ready to share your creation, but the process of publishing on the Microsoft Store seems daunting. This guide walks you through the essential steps, providing clarity and guidance along the way.
Step 1: Prepare Your Add-in
- Target platform: Determine your target platform (Office 365 or a specific version).
- Packaging: Create a "ClickOnce" deployment manifest for your add-in. This file defines how your add-in is installed and updated.
- Certificate: Obtain a code-signing certificate to ensure the integrity and authenticity of your add-in.
- Manifest: Update your add-in's manifest file with necessary information, including publisher name, product name, description, and version number.
Example:
<!-- Add-in manifest for an Excel add-in -->
<?xml version="1.0" encoding="utf-8" ?>
