To send binary content as the response in ASP.NET Core, you should use the FileResult action result. This result type allows you to send files, such as images, PDFs, or any binary data, in response to a client request. You can specify the file's content type, name, and other details.

In attribute routing, the order of route definitions is significant because it determines the priority of routes. Routes are evaluated in the order they are defined, and the first matching route is used. This allows you to control which route handles a particular request when there are multiple possible matches.

ASP.NET Core Identity provides the "Password Requirements" feature to specify criteria for user passwords, including the minimum length. This is essential for enforcing security standards, and developers can configure it as needed in their applications.

Azure App Service is a Platform-as-a-Service (PaaS) offering that allows developers to build, deploy, and scale web apps and APIs easily. It provides a fully managed environment for hosting ASP.NET Core applications in the Azure cloud.

To prevent a Razor form from being submitted if client-side validation fails, you can use the onsubmit attribute on the form element. By specifying a JavaScript function that returns false when validation fails, you can stop the form submission and show validation errors to the user.

To add a user to a specific role immediately after creating them programmatically, you would use the AddToRoleAsync method of the UserManager class. This method allows you to assign a user to a role, granting them the associated permissions and access rights.

The View component in ASP.NET Core MVC is responsible for determining how data is presented to the user. It defines the layout and structure of the page, including how the list of movies is displayed. The Controller manages user requests and interacts with the Model to retrieve the necessary data.

A common mistake leading to the issue of custom error handling logic not being triggered is incorrect middleware order. Middleware in ASP.NET Core is executed in the order they are added, and exception handling middleware should be placed early in the pipeline to capture exceptions before other middleware processes the request.

Entity Framework Core (EF Core) is primarily used for managing database operations in web applications. It provides an object-relational mapping (ORM) framework, allowing developers to work with databases using .NET objects, thus reducing the need to write extensive SQL code.

In the "Startup.cs" file of an ASP.NET Core application, the "ConfigureServices" method is used to add and configure middleware services. Middleware services are components that handle requests and responses as they flow through the application's request pipeline. The "ConfigureServices" method is where you register services such as database connections, authentication, and dependency injection.
