Microsoft Build 2023: Strengthening Developers via Microsoft 365 Copilot Plug-ins

Microsoft’s famous Build conference, held from May 23 to 25 in Seattle, Washington, brought exciting announcements for developers. This year’s focus was on artificial intelligence (AI) with announcements about innovative AI projects and future plans.

The first day saw some big reveals, including the collaboration between Microsoft and OpenAI to enrich and grow the AI plug-ins ecosystem. Microsoft has chosen an open standard for plug-ins that integrate seamlessly with OpenAI’s ChatGPT and Microsoft’s Copilot solutions such as Bing Chat, Dynamics 365 Copilot, Windows Copilot and Microsoft 365 Copilot. These are exciting times for AI and plug-in development!

Microsoft 365 Copilot – The future of natural language

There is a plethora of plug-ins available to Microsoft 365 Copilot users. These include Microsoft Power Platform connectors, Teams message extensions and ChatGPT plug-ins. The plug-ins are designed to make your life as a developer easier by integrating with your existing software, tools, knowledge and skills. There is always a plug-in waiting for you to improve your development skills, whether you prefer ChatGPT, Teams or the Power Platform.

Effortless plug-in creation with Teams Toolkit

Developers can use the Teams Toolkit for Visual Studio, Visual Studio Code and CLI to create Teams message extensions that work like Microsoft 365 Copilot plug-ins. With added functionality in the Teams Toolkit, Microsoft aims to simplify the process of developing, testing and debugging plug-ins. Developers can easily add any API of the OpenAPI specification to Microsoft 365 Copilot through the plug-in creation experience of the Teams Toolkit. This functionality is currently available in a private preview.

Customizing the user experience with adaptive maps

By using Adaptive Cards, developers can have complete control over user interface customization when their plug-in is used. Based on the metadata in the OpenAPI specification, the Teams Toolkit creates a plug-in consisting of a manifest and declarative Adaptive Cards, which define the Copilot user experience. Before testing their plug-in in Copilot, developers can further customize the manifest and maps to their specific scenario, including specifying login settings.

Enrich your data with the semantic index for Copilot

Microsoft Graph provides access to customer data related to compliance, security, privacy, productivity and collaboration. Copilot uses Microsoft Graph data to generate user prompts and responses, while providing permissions and security at runtime. Importantly, this data remains solely within the client’s tenants and is not used to train Microsoft’s base models.

Introduction of the semantic index for Copilot

The semantic index for Copilot is a complex map of user and business data that enables Copilot to display Microsoft Graph data. The semantic index captures semantics and relationships around content and users by constructing vector inclusions based on Microsoft Graph data. This allows Copilot to quickly search through billions of objects in a vector index using semantic search. To use the semantic index for Copilot, developers can use Graph connectors to upload their data to Microsoft Graph and receive personalized and useful results.

Access enterprise data with Microsoft Dynamics 365 and Power Platform Microsoft 365

Copilot now provides access to structured data from Microsoft Dynamics 365 and Microsoft Power Platform stored in Microsoft Dataverse, in addition to productivity and collaboration data in Microsoft Graph. Customers in the Microsoft 365 Copilot Early Access program will have the opportunity to test out this feature as Microsoft 365 Copilot is rolled out.

Developers shape the future of work with Microsoft 365 Copilot

As customers start using Microsoft 365 Copilot with connected apps and services, developers will be crucial in establishing new work patterns. In a simulation scenario, this potential is illustrated by a user at Dentsu Inc. using Microsoft 365 Copilot in conjunction with Atlassian’s Jira plug-ins and a line-of-business Dentsu app plug-in, and data from Atlassian’s Confluence integrated via a Microsoft Graph connector.

Accelerate success for any developer

With the new extension architecture for Microsoft 365 Copilot, developers can leverage their AI skills and reach millions of Microsoft 365 users. With comprehensive support for the entire app lifecycle, including tooling, distribution, management, commerce and enterprise readiness, developers can create plug-ins for Copilot with their existing knowledge, code and resources.

More innovations to improve app development

In addition to the extensibility of Copilot, there are other exciting developments to improve app development. Thanks to the Live Share SDK, Teams meetings can now collaborate in real time. Microsoft Teams’ configurable avatars and reactions and immersive spaces, both currently in private preview, increase engagement and transcend physical boundaries. Microsoft Mesh, also currently in private preview, allows developers to create unique, immersive experiences that promote connection and cohesion, no matter where users are physically located.

Explore the future of work with Microsoft 365 Copilot

If Microsoft 365 Copilot participates in the Early Access program, customers will soon be able to test the expansion features announced at Microsoft Build. By preparing for the release of Copilot, developers and partners can use all available tools and resources to get the most out of Microsoft 365 Copilot.
