Ignore SSL connection errors via IHttpClientFactory

Question

I have a problem with a connect from my asp.net core 2.2 project to an https site like there. I use IHttpClientFactory to create typed HttpClient in Startup.cs

services.AddHttpClient<ICustomService, MyCustomService>();

And I don't understand, how can I ignore SSL connection problems without creating HttpClient manually like this

using (var customHandler = new HttpClientHandler())
{
    customHandler.ServerCertificateCustomValidationCallback  = (m, c, ch, e) => { return true; };
    using (var customClient = new HttpClient(customHandler)
    {
        // my code
    }
}

Answer 1

Use ConfigureHttpMessageHandlerBuilder:

services.AddHttpClient<ICustomService, MyCustomService>()
    .ConfigureHttpMessageHandlerBuilder(builder =>
    {
        builder.PrimaryHandler = new HttpClientHandler
        {
            ServerCertificateCustomValidationCallback = (m, c, ch, e) => true
        };
    });
