ServerOptions custom properties and handling

[ghost]

Hello,

I´ve started a SuperSocket 1.6 service conversion to 2.0 on Net 8 environment and I stuck on how to configure the ServerOptions to keep the legacy config the server is using. In 1.6, for each config file there´s some customer/tenant information besides the Ip/Port/SSl config, so a new ServerOptions is created passing this custom info into the Options parameters. Now In 2.0 this property has gone and I dont know how to keep those custom info on the new SuperSocketHostBuilder´s ConfigureAppConfiguration method.

Also, ServerOption is not accessed on UsePackageHandler (or in IPackageHandler´s Handle method when using a middleware) , so to accesss the customer/tenant information on each request is impossible.

So I like to know if some new features could be added on SuperSocket 2.0:

1. Allowing ServerOptions to be extended to include some custom info;
2. Accessing ServerOptions on a multile server instances configuration, allowing to access the correspondent server instance custom config on packet handler/middleware.

Thanks

Ok, I missed this discussion. Let me think about it and reply to this ASAP.

Custom settings are still can be access from

server.Options.Values[propName]

SuperSocket/test/SuperSocket.Tests/MainTest.cs

Lines 82 to 96 in d9d70f4

	var hostConfigurator = new RegularHostConfigurator();
	var propName = "testPropName";
	var propValue = "testPropValue";
	using (var server = CreateSocketServerBuilder<TextPackageInfo, LinePipelineFilter>(hostConfigurator)
	.ConfigureAppConfiguration((HostBuilder, configBuilder) =>
	{
	configBuilder.AddInMemoryCollection(new Dictionary<string, string>
	{
	{ $"serverOptions:values:{propName}", propValue }
	});
	}).BuildAsServer())
	{
	Assert.Equal(propValue, server.Options.Values[propName]);
	}

If you want to have strong type access, I think you still have a way to do it. You can implement a your own service with the option type you want:

YouOwnService(IServiceProvider serviceProvider, IOptions<YourServerOptions> serverOptions)
: base(serviceProvider, serverOptions)

SuperSocket/src/SuperSocket.Server/SuperSocketService.cs

Lines 153 to 160 in d9d70f4

	/// <summary>
	/// Initializes a new instance of the <see cref="SuperSocketService{TReceivePackageInfo}"/> class.
	/// </summary>
	/// <param name="serviceProvider">The service provider for dependency injection.</param>
	/// <param name="serverOptions">The server options for configuration.</param>
	public SuperSocketService(IServiceProvider serviceProvider, IOptions<ServerOptions> serverOptions)
	{
	if (serviceProvider == null)
