ASP.NET Core is not supported anymore in latest 6.2.0!!?

This code should be executable in LINQPad 6 yesterday :

// this code is running under "Reference ASP.NET Core assemblies checked".
void Main()
{
    WebHost
        .CreateDefaultBuilder()
        .UseStartup<UserQuery>()
        .UseUrls("https://localhost:55555")
        .Build()
        .Run();
}

public void ConfigureServices(IServiceCollection services)
{
	services.AddControllers();
}

public void Configure(IApplicationBuilder app)
{
	app.UseRouting();
	app.UseEndpoints(endpoints =>
	{
		endpoints.MapControllerRoute(
					name: "default",
					pattern: "{controller}/{action}/{id?}",
					defaults: new { controller = "Home", action = "Index" });
	});
}

namespace Controllers
{
	public class HomeController : Controller
	{
		public DateTime Index()
		{
			return DateTime.Now;
		}
	}
}

But seems currently in latest LINQPad 6.2.0, this code will throw following exception:

Could not load file or assembly 'LINQPadQuery, Culture=neutral, PublicKeyToken=null'. 系统找不到指定的文件。

Not very sure if it's a bug in LINQPad or ASP.NET Core 3.0, but I believe LINQPad should/need be able to support this scenario.

Yeah~ I can confirm this is fixed in latest LINQPad 6.2.1

I've fixed an issue with assembly caching, too, so you can now do this:

Task Main() => WebHost
    .CreateDefaultBuilder()
    .UseStartup<Startup>()
    .Build()
    .RunAsync (QueryCancelToken);
