Benchmarking programming languages and web frameworks

ASP.NET Core (C#)

ASP.NET Core is a free and open-source web framework developed by Microsoft for building modern, cloud-based applications. It is a cross-platform redesign of ASP.NET that runs on Windows, Linux, and macOS. ASP.NET Core supports full-featured web applications and APIs with a focus on scalability and high performance.

This benchmark tests how fast a framework can perform concurrent HTTP requests, I/O operations, and JSON de/serialization.

About C#

Paradigm

Object-Oriented, Imperative, Event-Driven, Functional

Execution

JIT

Typing

Static

Null Safety

YES

Memory Management

Garbage Collection

C# is a modern, general-purpose programming language developed by Microsoft as part of its .NET initiative. It features static typing, null safety, and garbage collection. C# is primarily used on the .NET Framework for Windows application development but has grown to support cross-platform needs via .NET Core.
