You are building a mobile app for Android and iOS and manage work items and release cycles in Azure DevOps. You need crash reporting, beta distribution to testers, and a way to collect user feedback on new functionality. Which of the following must be included in your solution?

The Microsoft Test & Feedback extension (formerly Exploratory Testing extension) integrates directly with Azure DevOps to provide crash reporting, beta distribution, and user feedback collection for mobile apps. It allows testers to provide rich feedback, including screenshots, annotations, and crash logs, directly linked to work items in Azure DevOps. OWASP ZAP is a security testing tool, not for crash reporting or beta distribution. The TFS Integration Platform is an older tool for synchronizing data between Team Foundation Server and other systems, not relevant for mobile app testing. Code Style refers to coding conventions and static analysis, not crash reporting or beta distribution.
