Discover the top 50 dotnet core interview questions, organized into ten parts from dependency injection to caching, including Program.cs and Startup.cs, middleware, and Kestrel hosting.
Discover how dependency injection in .NET Core creates loosely coupled controllers and views by injecting interfaces, registering services in startup, and using constructor and view injection.
Define .NET Core, contrast with the .NET Framework, and outline .NET Standard as an API set, plus its open source, cross-platform nature and built-in dependency injection.
Explore the roles of program.cs and startup.cs in a .NET Core app, including the entry point, host builder, and startup configuration, and how configure services differs from configure.
Explore how middleware in ASP.NET Core forms a per-request pipeline, including built-in components like static files, routing, and authorization, plus creating custom middleware with use, run, and map.
Explore the three service lifetimes in .NET Core—singleton, scoped, and transient—and learn how their object lifetimes affect per-request behavior and overall application scope, with practical logging examples.
Explore in-process and out-of-process hosting in ASP.NET Core, compare Kestrel and IIS, and learn how to switch hosting models in the project file.
Discover the main files in asp.net core, including the wwwroot folder for static files, program.cs, startup.cs, and key configuration files like appsettings.json and launchSettings.json.
Explore routing fundamentals in ASP.NET Core MVC, including default routing and attribute routing, and trace the complete request processing pipeline from routing to action, result, and response.
Explore caching concepts in ASP.NET Core, including in-memory caching and distributed caching, and get guidance on when to use each for enterprise applications vs. simple web apps.
