Can you explain what RESTful API design is and how you would implement it in a C# application?

RESTful API design is an architectural style for designing networked applications using HTTP requests to access and use data. In a C# application, this can be implemented using ASP.NET Core,…

🏷️
Can you explain what a RESTful API is and how you would approach designing one in C#?

A RESTful API is a service that follows REST principles to allow clients to interact with resources over HTTP. In C#, I would use ASP.NET Core to create controllers for…

🏷️
How would you design a RESTful API in C# that allows clients to filter and sort resources flexibly, while ensuring optimal performance and scalability?

I would utilize ASP.NET Core along with OData for flexible querying, allowing clients to specify filtering and sorting through query parameters. Implementing pagination and caching strategies will help optimize performance,…
