What is the role of the wwwroot directory in an ASP.NET Core application?
- It contains compiled C# code.
- It stores configuration files.
- It hosts static web assets that can be directly accessed by clients.
- It's used for database migrations.
The role of the wwwroot directory in an ASP.NET Core application is to host static web assets, such as HTML files, images, JavaScript files, and CSS stylesheets. These assets are meant to be directly accessible by clients (e.g., web browsers) without going through server-side code. Placing static files in the wwwroot folder ensures they can be served efficiently and improves the performance of the web application.
Your team is starting a new project where you have an existing database, and you wish to generate your data models based on this database. Which approach in Entity Framework Core would be most suitable?
- Code-First
- Database-First
- Model-First
- Entity-First
In this scenario, the most suitable approach is "Database-First." This approach involves generating data models based on an existing database schema.
