Has anyone experienced this before? I am deploying an ASP.Net Core MVC 6 web app. Right now I am getting this error. It relates to my startup method. Ive check online and I have everything as it needs to be. I have added it to my publishOptions in my program.json, and I have a set base in my method as well.

 public Startup(IHostingEnvironment environment)
        var builder = new ConfigurationBuilder()

        Configuration = builder.Build();

If you have any suggestions please let me know!! Ive been struggling with this for a few weeks now.
