Which project template should I pick to start?
Use the ASP.NET Core Web API project template. The path uses Arm64.HeadlessIoT as an example project name, but any name works.
Where should I run `dotnet run` from?
Run it from the project directory that contains the .csproj file. This ensures the CLI builds and starts the correct project.
How do I know the server started correctly?
Check the console for lines such as Now listening on: http://localhost:PORT and Application started. Press Ctrl+C to shut down. The output also shows the hosting environment (for example, Development).
How do I access the API endpoint locally?
Open the exact localhost URL printed in the console in a browser or an HTTP client. Use the scheme, host, and port shown after “Now listening on:”.
How do I stop the server when I’m done?
Press Ctrl+C in the terminal where the app is running. The process exits and the server stops listening on the local port.
