What Exactly is the Microsoft Edge "Server Error In / Application"?

This error pops up when Microsoft Edge tries to load a web app (often ASP.NET-based) but encounters a server-side issue. You'll see a yellow screen with details like "Runtime Error" or config failures. It's not Edge's fault – it's the server (local IIS, Azure, or remote host) throwing a tantrum.

• Path shows "/" (root application).
• Messages like "An application error occurred" or detailed stack traces.
• Happens on localhost or specific sites in Edge.
