Fix S4507 FP: Error raised on .NET 7 although the debug feature is deactivated

[VianneyDoleans]

Description

I migrate a project to .NET 7. The error S4507 is raised although the debug feature is desactivated in production mode.

Repro steps

Code inside program.cs :

var builder = WebApplication.CreateBuilder(args);

var app = builder.Build();

app.UseExceptionHandler("/error");
if (app.Environment.IsDevelopment())
    app.UseDeveloperExceptionPage();
else
    app.UseHsts();

Link to the SonarCloud public project where the issue appears : link

Expected behavior

Code is already deactivated so it should not be highlighted

Actual behavior

The error S4507 is raised.

Related information

• .NET 7
• I suppose the problem is related to minimal hosting model introduced with .NET 6.

Thanks for the reporting and the detailed description @VianneyDoleans. I created a reproducer in #6777 on our side and confirm this being an FP.

@zsolt-kolbay-sonarsource We are releasing 9.19 for SQ 10.4, and this issue is not going to make it into the release.
I am removing the Sprint: Hardening label to close the sprint, but I am leaving it on the board since its review is in progress and we may get it to a mergeable state in the coming days.
