This document summarizes a webinar about developing customizations for Microsoft Teams using the SharePoint Framework (SPFx). The webinar will cover how any SPFx web part can be used as a custom tab in Teams, leveraging SPFx APIs and functionalities. It will also discuss the options for deploying SPFx-based Teams apps by packaging and deploying to the Teams app catalog from SharePoint, or by manually creating a Teams app manifest and package. The goal is to demonstrate how developers can build custom solutions for Teams using the existing SPFx tools and infrastructure.
