sm new project: scaffold references /favicon.svg but ships none → 404 #225
Description
Summary
A fresh sm new project scaffold references a favicon that it doesn't ship, producing a 404 on every page.
Details
- The host
Program.csmaps/favicon.icotowwwroot/favicon.svg:app.MapGet("/favicon.ico", (IWebHostEnvironment env) => Results.File(Path.Combine(env.WebRootPath, "favicon.svg"), "image/svg+xml")) .ExcludeFromDescription().AllowAnonymous();
- The rendered HTML shell links
<link rel="icon" type="image/svg+xml" href="/favicon.svg">. - But no
favicon.svgexists underwwwroot/, so both requests 404.
Actual
GET /favicon.svg 404 (Not Found)
Suggested fix
Ship a default wwwroot/favicon.svg in the scaffold.
Severity
Low.
Environment
smCLI 0.0.37, .NET SDK 10.0.202, Linux.

Correction: in practice this is a 500, not a 404 —
Program.csmaps/favicon.icotoResults.File(Path.Combine(env.WebRootPath, "favicon.svg"), ...), andResults.FilethrowsSystem.IO.FileNotFoundExceptionwhen the file is missing, which the global exception handler turns into a 500 on every/favicon.icorequest (and the shell's<link rel=icon href=/favicon.svg>404s separately).fix(cli): resolve scaffold build/runtime bugs (#218, #219, #221, #225, …
