aspnetcore: Add an option to disable DeveloperExceptionPageMiddleware with WebApplication / Minimal APIs

Is there an existing issue for this?

Is your feature request related to a problem? Please describe the problem.

Hi, I want to have an option to disable preconfigured (implicit) middlewares and I can’t remove DeveloperExceptionPageMiddleware / (.UseDeveloperExceptionPage call).

I don’t want to use WebHostBuilder because according to the docs it’s deprecated:

This article covers the Web Host, which remains available only for backward compatibility. The ASP.NET Core templates create a WebApplicationBuilder and WebApplication, which is recommended for web apps.

I don’t want to wrap and catch with my middleware after the developer exception middleware, because it’s an ugly workaround and produces unnecessary allocations and useless work per request.

docs source

Describe the solution you’d like

Add an option to disable implicit middleware logic or at least have an option to disable .UseDeveloperExceptionPage in Development environment too.

Additional context

Hardcoded part of WebApplicationBuilder:
