== Eager service bean instantiation ==
To instantiate a service/bean before being used else where add it as an argument in the Configure method that belongs to the Startup class.
== RBAC role based authorization ==
* https://docs.microsoft.com/en-us/aspnet/core/security/authentication/identity?view=aspnetcore-2.0&tabs=visual-studio%2Caspnetcore2x
* https://docs.microsoft.com/en-us/aspnet/core/security/authorization/secure-data?view=aspnetcore-2.0
* https://docs.microsoft.com/en-us/aspnet/core/security/authorization/roles?view=aspnetcore-2.0
* https://docs.microsoft.com/en-us/aspnet/core/mvc/models/file-uploads?view=aspnetcore-2.0
Identity is enabled for the application by calling UseAuthentication in the Configure method. Startup.cs in dotnet core to init the services/beans.
In ASP.NET Core MVC, views are .cshtml files that use the C# programming language in Razor markup.
* About.cshtml
{{{
@{
ViewData["Title"] = "About";
}
@ViewData["Title"].
@ViewData["Message"]
Use this area to provide additional information.
}}}
* HomeController.cs
{{{#!highlight csharp
// method About related with About.cshtml
// ViewData["Message"] defined in the method and accessed inside the view in the About.cshtml
public IActionResult About()
{
ViewData["Message"] = "Your application description page.";
return View();
// return explicit view Orders
// return View("Orders");
// return both a view and a model
// return View("Orders", Orders);
}
}}}
View discovery searches for a matching view file in this order:
* Views/[ControllerName]/[ViewName].cshtml
* Views/Shared/[ViewName].cshtml
Pass data to views using several approaches:
* Strongly-typed data: viewmodel
* Weakly-typed data
* ViewData (ViewDataAttribute)
* ViewBag
Strong type sample
{{{
// CSHTML
@model WebApplication1.ViewModels.Address
Contact
@Model.Street
@Model.City, @Model.State @Model.PostalCode
P: 425.555.0100
To provide the model to the view, the controller passes it as a parameter:
// C#
public IActionResult Contact()
{
ViewData["Message"] = "Your contact page.";
var viewModel = new Address()
{
Name = "Microsoft",
Street = "One Microsoft Way",
City = "Redmond",
State = "WA",
PostalCode = "98052-6399"
};
return View(viewModel);
}
}}}
Angular automatically passes an antiforgery token in a request header named X-XSRF-TOKEN. The ASP.NET Core MVC app is configured to refer to this header in its configuration in Startup.cs:
{{{
public void ConfigureServices(IServiceCollection services)
{
// Angular's default header name for sending the XSRF token.
services.AddAntiforgery(options => options.HeaderName = "X-XSRF-TOKEN");
services.AddMvc();
}
}}}

* yum install epel-release

== Kestrel ==
* https://docs.microsoft.com/en-us/aspnet/core/fundamentals/servers/kestrel?view=aspnetcore-3.1
Kestrel is a cross-platform web server for ASP.NET Core. Kestrel is the web server that's included by default in ASP.NET Core project templates.
Kestrel supports the following scenarios:
* HTTPS
* Opaque upgrade used to enable WebSockets
* Unix sockets for high performance behind Nginx
* HTTP/2 (except on macOS†)
