Web App Troubleshooting

To troubleshoot your web app, you can set the subscribeToOpenIdConnectMiddlewareDiagnosticsEvents optional boolean to true when you call AddMicrosoftWebAppAuthentication or AddMicrosoftWebApp (used to be AddSignIn). This displays in the output window the progression of the OpenID connect message through the OpenID Connect middleware (from the reception of the message from Azure Active directory to the availability of the user identity in HttpContext.User).
