[c#] bypass invalid SSL certificate in .net core

Firstly, DO NOT USE IT IN PRODUCTION

If you are using AddHttpClient middleware this will be usefull. I think it is needed for development purpose not production. Until you create a valid certificate you could use this Func.

Func<HttpMessageHandler> configureHandler = () =>
        {
            var bypassCertValidation = Configuration.GetValue<bool>("BypassRemoteCertificateValidation");
            var handler = new HttpClientHandler();
            //!DO NOT DO IT IN PRODUCTION!! GO AND CREATE VALID CERTIFICATE!
            if (bypassCertValidation)
            {
                handler.ServerCertificateCustomValidationCallback = (httpRequestMessage, x509Certificate2, x509Chain, sslPolicyErrors) =>
                {
                    return true;
                };
            }
            return handler;
        };

and apply it like

services.AddHttpClient<IMyClient, MyClient>(x => { x.BaseAddress = new Uri("https://localhost:5005"); })
        .ConfigurePrimaryHttpMessageHandler(configureHandler);
