To pass both product details and a list of related reviews to a view, it's best to use a ViewModel. A ViewModel is a dedicated class that combines the necessary data for a view. This approach keeps your code clean, maintainable, and allows for strong typing in your view.

When you need to create custom constraints for routing in ASP.NET Core, you should implement the IRouteConstraint interface. This interface allows you to define your custom logic to determine if a route is a match or not, providing flexibility in routing scenarios.

ASP.NET Core MVC determines the controller and action to route a request to through URL routing. The routing system maps incoming URLs to controller actions based on predefined route patterns, allowing for a clean and user-friendly URL structure in your web application.

To dynamically choose a Razor view based on runtime conditions, you can use Razor Views with Resource Files. These resource files can store localized versions of your views, and you can switch between them based on the user's language preference.

The 'dotnet run' command is used to run .NET applications. It compiles and runs the source code in a single step, making it convenient for developers during the development and debugging process. This command is particularly handy for quickly testing and executing code without the need to explicitly compile it before execution.

In ASP.NET Core, the UrlHelper class provides methods to generate URLs. It allows you to create URLs for different routes and actions in your application. You can access the UrlHelper within your controller or Razor views to generate URLs that point to specific routes or actions.

Razor Pages is a great starting point for creating websites with static pages. It's a lightweight framework in ASP.NET Core designed for creating web pages without the complexities of full MVC. Razor Pages allow you to build simple, static web pages efficiently.

Role-Based Authorization is a key feature of ASP.NET Core Identity that allows you to manage user roles and claims. It enables fine-grained access control by associating users with specific roles and defining role-based policies for authorization.

To specify the SDK version for a .NET project, you should add a "global.json" file to the project's root directory. This JSON file allows you to define the desired SDK version, ensuring consistency among team members and across development environments.

Razor Partials are reusable components in Razor views. They allow you to define a piece of HTML and C# code once and then include it in multiple views. This approach ensures code reusability and reduces duplication.
