SDK 101 starter: .NET

Requires the .NET 10 SDK and authenticated Copilot access.

From the workshop repository root:

cd start-intro/dotnet
dotnet restore

Open this folder in your editor (code .) and edit Program.cs by following the four numbered edits in LIVE_DEMO.md, Act One. Then run:

dotnet run

The untouched entrypoint is deliberately incomplete, not a working hello world. Continue with Act Two in the same guide for the podcast agent. Reuse the prebuilt Helpers/ and Tools/ code without editing it.

The SDK bundles a compatible runtime. If its download is blocked or the CLI cannot be found, install and authenticate the native Copilot CLI first. The repository's Directory.Build.props recognizes common CLI locations. For another installation, set COPILOT_CLI_BINARY_PATH to its native executable. For example, on Windows PowerShell:

$env:COPILOT_CLI_BINARY_PATH = (Get-Command copilot.exe).Source
dotnet run

See preflight for access checks and troubleshooting, and the official .NET SDK API for reference.
