Before running the applications in this repository, ensure you have:

• .NET 10 SDK or later
• Visual Studio 2025 or Visual Studio Code
• PowerShell (for scripts)

• Azure subscription
• Azure OpenAI resource
• Azure AI Search service

• Microsoft 365 Developer tenant
• Teams Toolkit
• Microsoft 365 Agents Playground (for M365Agent solution)

• AI Toolkit for VS Code (optional, for enhanced AI development experience)

git clone https://github.com/qmatteoq/NetConf2025.git
cd NetConf2025

1. Create an Azure AI Search service (for TeamsAgent solution)
2. Create an Azure OpenAI resource (for both solutions)
3. Note down the connection strings and API keys

Update the appsettings.Development.json files in each solution with your Azure service configurations.

# Navigate to the M365Agent directory
cd M365Agent

# Restore dependencies
dotnet restore

# Build the solution
dotnet build

# Run the AppHost (this will start the API and App services)
dotnet run --project M365Agent.AppHost

The M365Agent solution will:

• Start the API service with the LearnAgent
• Start the bot application compatible with M365 Agents Playground
• Create a dev tunnel for external access
• Optionally launch the M365 Agents Playground emulator

# Navigate to the TeamsAgent directory
cd TeamsAgent

# Restore dependencies
dotnet restore

# Build the solution
dotnet build

# Run the AppHost (this will start all services)
dotnet run --project TeamsAgent.AppHost

For the Teams Agent specifically:

1. Run the Indexer.ps1 script to create your document index
2. Configure your Teams app manifest
3. Deploy to Teams for testing
