C# vs OCaml: What are the differences?

Introduction

C# and OCaml are two distinct programming languages with their own unique features and functionalities. While C# is an object-oriented language developed by Microsoft, OCaml is a functional programming language with a strong static type system. In this article, we will discuss the key differences between C# and OCaml.

  1. Syntax: The syntax of C# is inspired by C and C++, making it more similar to other popular programming languages. On the other hand, OCaml has a syntax that is based on the ML family of programming languages, which makes it quite different from languages like C#.

  2. Type Systems: C# is statically-typed and has a rich type system that supports features like generics, interfaces, and inheritance. It also provides support for dynamic typing through the dynamic keyword. In contrast, OCaml has a strong static type system that infers types automatically and enforces type safety at compile-time. It also supports type inference, which reduces the need for explicit type annotations in code.

  3. Programming Paradigm: While C# is primarily an object-oriented programming language, OCaml is a functional programming language. This means that C# focuses on encapsulating data within objects and using classes and inheritance to define behavior, whereas OCaml emphasizes the use of functions and immutable data structures.

  4. Memory Management: C# uses a garbage collector to automatically reclaim memory that is no longer in use, which makes memory management easier for developers. OCaml, on the other hand, uses a combination of garbage collection and manual memory management through the use of reference counting. This allows for better control over memory usage but requires more manual intervention.

  5. Tooling and Ecosystem: C# has extensive tooling and a large ecosystem supported by Microsoft, including an Integrated Development Environment (IDE) like Visual Studio and a package manager called NuGet. OCaml, although less widely used, also has its own set of development tools like the OCaml Compiler and package manager called OPAM.

  6. Community and Industry Adoption: C# has seen widespread adoption in the industry, especially in the Microsoft ecosystem, and is used for a wide range of applications, including web development, game development, and mobile app development. OCaml, on the other hand, has a smaller but dedicated community of developers and is often used in areas like formal verification, compiler writing, and academic research.

In Summary, C# and OCaml differ in their syntax, type systems, programming paradigms, memory management approaches, tooling and ecosystem, as well as their community and industry adoption.

Decisions about C# and OCaml

In 2015 as Xelex Digital was paving a new technology path, moving from ASP.NET web services and web applications, we knew that we wanted to move to a more modular decoupled base of applications centered around REST APIs.

To that end we spent several months studying API design patterns and decided to use our own adaptation of CRUD, specifically a SCRUD pattern that elevates query params to a more central role via the Search action.

Once we nailed down the API design pattern it was time to decide what language(s) our new APIs would be built upon. Our team has always been driven by the right tool for the job rather than what we know best. That said, in balancing practicality we chose to focus on 3 options that our team had deep experience with and knew the pros and cons of.

For us it came down to C#, JavaScript, and Ruby. At the time we owned our infrastructure, racks in cages, that were all loaded with Windows. We were also at a point that we were using that infrastructure to it's fullest and could not afford additional servers running Linux. That's a long way of saying we decided against Ruby as it doesn't play nice on Windows.

That left us with two options. We went a very unconventional route for deciding between the two. We built MVP APIs on both. The interfaces were identical and interchangeable. What we found was easily quantifiable differences.

We were able to iterate on our Node based APIs much more rapidly than we were our C# APIs. For us this was owed to the community coupled with the extremely dynamic nature of JS. There were tradeoffs we considered, latency was (acceptably) higher on requests to our Node APIs. No strong types to protect us from ourselves, but we've rarely found that to be an issue.

As such we decided to commit resources to our Node APIs and push it out as the core brain of our new system. We haven't looked back since. It has consistently met our needs, scaling with us, getting better with time as continually pour into and expand our capabilities.

C# and .Net were obvious choices for us at LiveTiles given our investment in the Microsoft ecosystem. It enabled us to harness of the .Net framework to build ASP.Net MVC, WebAPI, and Serverless applications very easily. Coupled with the high productivity of Visual Studio, it's the native tongue of Microsoft technology.

What is C#?

C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers.

What is OCaml?

It is an industrial strength programming language supporting functional, imperative and object-oriented styles. It is the technology of choice in companies where a single mistake can cost millions and speed matters,

What are some alternatives to C# and OCaml?
Java
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
Python
Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
JavaScript
JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.
Golang
Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
HTML5
HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.
