The RouteName property of the route attribute allows developers to name a route explicitly. Naming routes is especially useful when generating URLs later in the application, as it provides a more robust and maintainable way to refer to routes.

In Visual Studio, the Immediate window is a powerful tool for developers. It allows them to execute C# code directly during debugging sessions. It's particularly useful for evaluating expressions, testing code snippets, and understanding program behavior in real-time. Developers can use the Immediate window to interactively work with their code and variables.

The ASP.NET Core project definition is primarily saved in a .json (JavaScript Object Notation) file format. This JSON file, often named "project.json" or "*.csproj," contains essential project configuration information, dependencies, and build settings. It's used by the build system to compile and manage the project.

To enforce strict null checking in Razor views, you can enable nullable reference types by using the "#nullable" directive at the top of your Razor file. This allows the compiler to detect potential null reference issues at compile-time, reducing runtime errors.

In integration testing, it's common to mock HTTP requests. This ensures that the tests don't interact with the real database or external services, preventing unintended side effects on actual data during testing.

Routing in an ASP.NET Core MVC application is typically configured in the Configure method of the Startup.cs file. This method sets up the request processing pipeline, including routing rules for different URL patterns.

ASP.NET Core Identity simplifies the implementation of two-factor authentication by offering built-in support. This means that developers can easily enable and configure two-factor authentication for user accounts within their applications, adding an extra layer of security through methods like SMS codes or authenticator apps.

The "wwwroot" directory in an ASP.NET Core project serves as the location for static web assets that can be directly accessed by clients. These assets include HTML, CSS, JavaScript files, images, and other client-side resources. Placing them here ensures that they are publicly available without needing special routing or controller actions.

Entity Framework Core (EF Core) is the ORM framework natively supported by ASP.NET Core. It simplifies database access by allowing developers to work with databases using C# objects, making it a popular choice for database interaction in ASP.NET Core applications.

To serve static files like images, CSS, and JavaScript in ASP.NET Core, you need to add the StaticFile middleware. This middleware enables your application to serve these files efficiently without needing to write custom code for each file request. It's essential for building web applications with static assets.

To implement a public order tracking feature, you should create a separate controller or action without the [Authorize] attribute. This allows unauthenticated users to access order tracking while keeping the rest of the order management secure with authentication.

In ASP.NET Core, the ConfigureServices method in the Startup.cs file is used to configure services, including registering dependencies for dependency injection. This method allows you to configure how various parts of your application should interact and obtain the services they need.
