The project.json file was replaced by the .csproj file in .NET Core 2.0 and later versions. .csproj files use XML to define project structure and dependencies, replacing the simpler JSON-based project.json format.

In attribute routing, when specifying the 'Order' property, a lower value indicates a higher priority. So, the route with 'Order = 2' will prioritize this route above other routes with no order specified. This allows you to control the order in which routes are matched and executed.

To enhance your coding experience in Visual Studio Code for C# development, you would typically add Visual Studio Code Extensions. These extensions provide features like IntelliSense, debugging support, code navigation, and more specific to C# development within the lightweight Visual Studio Code editor.

The .NET SDK includes tools for producing Managed assemblies. Managed assemblies contain Intermediate Language (IL) code and metadata that the Common Language Runtime (CLR) can execute. These assemblies are not directly compiled to machine code but are Just-In-Time (JIT) compiled at runtime by the CLR, allowing for platform-independent execution.

The Model component in the MVC pattern is responsible for managing data and business logic. In this scenario, the Model would be best suited to decide which data to fetch from various sources (such as databases, APIs, or other services) and how to process that data for display in the dashboard. The Model abstracts data retrieval and processing details from the Controller and View.

Starting from .NET Core 2.0 and later, the project.json file was replaced with the .csproj file format for handling project configurations. The .csproj file is an XML-based project file that contains information about the project's structure, dependencies, and settings.

Razor views support C# Code Blocks, which allow developers to embed server-side logic directly within the HTML markup. This is a powerful feature of Razor that enables dynamic content generation.

In an ASP.NET Core MVC application, the Razor view files are typically located in the "Views" directory. These view files use the Razor syntax to define the HTML structure of the application's user interface. Views are responsible for rendering data provided by controllers to create the final web page that users interact with.

In Razor syntax, the "@" symbol is used to denote the start of server-side code. This allows developers to seamlessly transition between HTML markup and C# code within a Razor view.

The "API" template in ASP.NET Core is specifically designed to configure a project for building web applications that primarily expose web APIs. This template sets up the project with minimal middleware and settings for handling HTTP requests and responses, making it suitable for building RESTful APIs.
