[fabianwilliams]

Motivation and Context

Why is this change required?

The change is required to empower developers with intuitive, flexible tools that strengthen Copilot extensibility. This enables the creation of seamless GenAI experiences that meet users' unique needs, bringing joy and accomplishment as their vision comes to life with a faster journey to F51.

####What problem does it solve?

It solves the problem of navigating thousands of endpoints and methods in the Microsoft Graph OpenAPI document, which exceeds 800K lines. Traditional methods are inefficient and lack precision1.

####What scenario does it contribute to?

It contributes to scenarios where developers need to create, manage, and deploy CRUD (Create, Read, Update, Delete) plugins for M365. This includes operations on M365 resources like Mail, Calendar, and Contacts1.

Not sure if separate solution file is needed, can we add this demo project to SK-dotnet.sln? In this way, when we build main solution, this project will be included as well and it should be easier to keep this demo project up to date in case we release some breaking changes in our other packages.
