In a project review, you noticed that the production database connection string is exposed in appsettings.json. How should you securely manage this connection string in an ASP.NET Core application?
- Use User Secrets
- Encrypt the appsettings.json file
- Store it in an environment variable
- Use a configuration file in the project root
In an ASP.NET Core application, it's not secure to expose sensitive information like a production database connection string in appsettings.json. To securely manage it, you should store it in an environment variable. This approach helps protect sensitive data from accidental exposure and is a best practice for configuration management in production environments.
The _________ file in an ASP.NET Core project helps specify the SDK version and other project-related configurations.
- appsettings.json
- Program.cs
- Startup.cs
- .csproj
In an ASP.NET Core project, the .csproj (C# project) file is crucial for specifying the SDK version, dependencies, and various project-related configurations. It serves as the project file that orchestrates the build process and defines the project structure.
What is the primary purpose of the DbContext class in Entity Framework Core?
- Managing database connections and providing a high-level data access API
- Rendering user interfaces
- Handling HTTP requests
- Creating authentication tokens
The DbContext class in Entity Framework Core serves as the bridge between your application code and the database. Its primary purpose is to manage database connections, handle database operations, and provide a high-level data access API for interacting with the database. It abstracts the underlying database operations, making it easier to work with databases in your application.
When considering long-term scalability, which template should be avoided for large-scale applications due to its server-side rendering nature?
- Web Application (Razor Pages)
- Web API
- Web Application
- Blazor Server
The "Web Application (Razor Pages)" template uses server-side rendering, where most of the processing occurs on the server before rendering content to the client. This can be a scalability bottleneck for large-scale applications with high traffic because it places a significant load on the server. Web APIs and client-side rendering approaches like Blazor Server are typically preferred for such scenarios.
The _______ file in ASP.NET Core Razor views specifies the default layout for the views.
- _ViewStart.cshtml
- _Layout.cshtml
- _Default.cshtml
- _Config.cshtml
The correct file to specify the default layout for Razor views in ASP.NET Core is _ViewStart.cshtml. This file allows you to set the layout that should be applied to multiple views in a folder or the entire application.
In an ASP.NET Core MVC application for a library, where would the information about available books and their details be stored?
- In a Database
- In a Controller
- In a View
- In a CSS File
In an ASP.NET Core MVC application, information about available books and their details is typically stored in a database. The Model (M) in MVC is responsible for managing data, and databases are commonly used for persistent data storage in such applications. Controllers handle user requests and orchestrate interactions with the Model to retrieve and display this data.
To create a user programmatically in ASP.NET Core, you would typically make use of which method?
- CreateUserAsync
- CreateAsync
- AddUser
- RegisterUser
To create a user programmatically in ASP.NET Core Identity, you would typically make use of the CreateAsync method provided by the UserManager class. This method allows you to create a new user by specifying their details and asynchronously adds them to the user store.
What kind of testing is primarily focused on testing the interactions between different parts of a system, like services, databases, and external systems?
- Integration Testing
- Unit Testing
- Performance Testing
- User Acceptance Testing
Integration testing is specifically designed to test how different parts of a system work together. In the context of ASP.NET Core, it checks the interactions between services, databases, and external systems to ensure that they function correctly as a whole.
After setting up your ASP.NET Core development environment, you need to ensure that the application can be containerized. What would be your primary focus when adjusting the development setup?
- Implement Dependency Injection
- Optimize Database Queries
- Create Docker Containers
- Configure Logging
The primary focus when adjusting the development setup for containerization should be on creating Docker containers. Containerization is a crucial step for portability and scalability, allowing you to package your ASP.NET Core application and its dependencies for deployment in various environments.
You're working on an ASP.NET Core application and you've been tasked to create a form that allows users to edit their profiles. After submitting the form, you want the data to be validated on the server side and any validation errors to be displayed next to the respective form fields. What combination of tools and methods would you employ to achieve this?
- Model Validation Attributes and Partial Views
- Client-side JavaScript Validation and Web API Endpoints
- Server-side Blazor Components and AJAX Calls
- ASP.NET Core Middleware and jQuery
To achieve server-side validation and display validation errors next to form fields, you can use Model Validation Attributes along with Partial Views in ASP.NET Core. Model Validation Attributes allow you to annotate your model properties with validation rules, and Partial Views enable you to render the form fields and errors in a modular way.
