I spent 3 hours debugging a React + ASP.NET setup.

The "official" tutorial missed ONE critical step.

My React app kept showing proxy errors.

The backend is throwing ECONNREFUSED on /api calls.

Two console windows are running.

Frontend timing out before backend started.

The fix? Startup project order in Visual Studio.

The Backend MUST start before the frontend proxy kicks in.

What's your biggest full-stack setup gotcha?

Ever lost hours on "simple" project templates?
