I have ASP.NET 3.0 Application, I am getting error as IHostBuilder does not contain definition of UseKestrel. Can I Use UseKestrel or ConfigureKestrel In ASP.NET 3.0 ?
.ConfigureWebHostDefaults(webBuilder =>
{
// .UseKestrel() not needed because its the default
webBuilder.ConfigureKestrel(options => {
});
webBuilder.UseStartup<Startup>();
});
You just share the part of program.cs.What is your whole program.cs and Startup.cs?Please share a simple demo which could reproduce the issue.Otherwise,we can't reproduce your issue and help you resolve it.

public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureLogging(logging => { logging.ClearProviders(); logging.AddConsole(); }) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseKestrel(options => {} ); webBuilder.UseStartup<Startup>(); });that is correct. UseKestrel() is an extension method for a IWebHostBuilder. use the ConfigeWebHostDefaults() extension method:

Hi TechAspirant,
> IHostBuilder does not contain definition of UseKestrel
IHostBuilder contains the definition of UseKestrel.
