To ensure that only the blog author can edit or delete a post, you would apply the [Authorize] attribute to the Edit and Delete actions in the controller. This allows you to specify authorization at the action level, and you can further customize it to check if the user making the request is the author of the post being edited or deleted. Applying [Authorize] to the entire controller would restrict access to all actions within it, which is not the desired behavior in this case. [Authorize(Roles = "Admin")] is role-based authorization and doesn't address this scenario, and [AllowAnonymous] would allow everyone, which is the opposite of the desired behavior.

After code is committed to a version control system (e.g., Git), the next typical step in a CI/CD (Continuous Integration/Continuous Deployment) pipeline is the build process. During the build, the code is compiled, tested, and packaged, preparing it for deployment to different environments.

Optimistic Concurrency is a technique used in Entity Framework Core to handle concurrent updates. When enabled, it checks if a record has been modified by another user since it was loaded, and if so, it prevents the update, ensuring data integrity and preventing data loss due to overwrites.

The crucial file for defining the environment and settings of a Docker container for an ASP.NET Core application is the Dockerfile. This file contains instructions on how to build the container image, what base image to use, and how to configure the environment.

During unit testing, real services or components that are external to the unit being tested are often replaced with mocks or stubs. Mocks provide controlled behavior for testing without relying on the actual implementations of these external components.

The primary difference between _ViewImports.cshtml and _ViewStart.cshtml in Razor is their purpose. _ViewImports.cshtml is used to set directives, namespaces, and base class declarations for views, whereas _ViewStart.cshtml is used to specify common layout code and execute code before rendering views. _ViewStart.cshtml is typically used to set layout and execute code that should apply globally to multiple views.

JSON Web Tokens (JWT) is an authentication approach commonly used in ASP.NET Core Web APIs. JWTs are compact and URL-safe, making them efficient for transferring claims between parties. They provide a secure way to represent user identities and access permissions.

In ASP.NET Core Identity, the "Password History" option helps enforce password policies by preventing users from reusing recent passwords. It maintains a history of previously used passwords and checks new passwords against this history to ensure they are not reused.

In the URL /Books/Details/3, the "3" is a route parameter. Route parameters allow you to pass data from the URL to your controller actions, making it dynamic and allowing you to retrieve information specific to the value "3."

Exception handling in ASP.NET Core is crucial for maintaining the stability and reliability of applications. It allows developers to gracefully handle errors, provide meaningful error messages to users, and prevent crashes that could otherwise disrupt the user experience.
