Developing applications for Teams means placing your tools at the center of company collaboration. ## Types of Teams Apps Teams offers several extension surfaces: - Tabs: Embedded web pages (similar to iframes) that can be contextual to a channel or chat. - Bots: Conversational interfaces to automate tasks and answer questions. - Message Extensions: Allow searching and sharing information from external systems directly in the message composition box. - Meeting Extensions: Apps that enrich the experience during meetings. ## Teams Toolkit Microsoft has greatly facilitated development with the Teams Toolkit for VS Code. This plugin offers templates, automatic resource configuration in Azure and Microsoft 365, and a simplified debugging experience. ## Design for Collaboration Creating an app for Teams is not just porting a web app. You need to think about collaboration scenarios: - How does my app help a team make decisions? - How can notifications (Adaptive Cards) be actionable? - How can I use user context (Graph API) to pre-fill information? At [Avantit](https://www.avantit.pt/en/about/), we create solutions that transform Teams from a simple chat tool into a productivity hub integrated with the company's business processes. #### Editorial Policy At Avantit, we value authenticity and human expertise.
