The next important part is when you are setting up HAXM (for intel based chips)

From a cmd window.

sc query intelhaxm  (and if it is not already installed go here HAXM Release on GitHub

sc stop intelhaxm – to stop the service
sc start intelhaxm – to start the service

You can also use Hyper-V (sometimes I have issue with this method because it likes to mess about with my wifi/lan connections- that’s sometimes not a pretty sight in Windows 10).

I’m not sure I like putting Kestrel options up the in the Main Program builder. I tend to prefer these to collect in the startup class, but I get point of why Kestrel needs to be handled close to the Builder (it is after all the html service handling web calls).

Shall we begin…
So up in program.cs we do our normal Web Host Builder:

public class Program
{
    public static void Main(string[] args)
    {
        var host = CreateWebHostBuilder(args).Build();

        MigrateDatabase(host);

        host.Run();
        //CreateWebHostBuilder(args).Build().Run();
    }

    private static void MigrateDatabase(IWebHost host)
    {
        using (var scope = host.Services.CreateScope())
        {
            var db = scope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
            db.Database.Migrate();
        }
    }

    public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .UseStartup<Startup>();
}

This tends to be my way of doing Program.cs. Note I split out the Build part into a static method (the normal default way is to have one fluent state that does a build and run in single line- it’s that commented line in the Main method) 

public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup$lt;Startup>()
                .ConfigureKestrel(opts =>
                {
                    opts.Limits.MaxConcurrentConnections = 100;

                });

 In my example, the method I push Kestrel setting to would of course have the .ConfigureKestrel with it’s options settings… 

Check it out… lots of interesting tweaks on settings…

One can go to a lower EF Core version, well mostly… I’ve yet to get my Blazor Hosted Core test app to compile…. let alone the DB-Context to Scaffold… it just spews errors no matter which direction I go in… Oh Bother….

I have to remember that Blazor is “Experimental” – But it would be nice if would keep up with the forward moving components like EF Core and the latest VS releases. I wonder what all of the Blazor Template releases are doing- seems like each time I run up VS there’s a new Blazor Lang Update. Curious…
