Problem with redirect to https for www. domain

I have a website in MVC Core C#. I have a naked domain softwareblogs.com. I need to redirect requests to https://www.softwareblogs.com. I used IIS URL Rewrite to redirect naked domain to www. domain. I used app.UseHttpsRedirection() in Startup.cs/Config method to redirect to https. But people complain when first time access my site, it said the site has no https. Can anyone help me with the property solution to resolve this issue?
