The Arc4u documentation has moved to https://arc4u-org.github.io/Arc4u/.

The StatusCodes page stays. The type URIs of the ProblemDetails returned by Arc4u link to its anchors (#unexpected-error, #expected-error and #validation-error from Arc4u.AspNetCore.Results, #unauthorized from ManageExceptionsFilter in Arc4u.OAuth2.AspNetCore). Do not rename the page or its headings.
