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.

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.

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.

What is the primary role of the .NET SDK in the context of ASP.NET Core development?
- Building and Compiling ASP.NET Core Applications
- Debugging ASP.NET Core Applications
- Handling Web Server Requests
- Managing Database Connections
The .NET SDK (Software Development Kit) plays a crucial role in ASP.NET Core development by providing the tools necessary for building and compiling ASP.NET Core applications. It includes the command-line interface (CLI) tools like 'dotnet' for project management, building, and running applications. Debugging, database management, and web server request handling are tasks typically handled by other components of the development stack.
