C# (pronounced C sharp) is a general-purpose, multi-paradigm programming language encompassing strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed around 2000 by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2018). C# is one of the programming languages designed for the Common Language Infrastructure.

### 5/5 — outputisn't work in persian .

*2025-05-25*

outputisn't work in persian .fix it

### 1/5 — Выдает переменные и русские буквы за ошибки

*2024-10-08*

Разработчик даже не пытается что либо поменять

### 5/5 — Good as reasonable

*2024-04-23, version 2.2.1*

It’s a good app allowing you to write and compile csharp remotely. Struggles with bigger programs as you’d expect it’s a mobile compiler but for small projects (100-200 lines of code max personally found) or individual functions it’s perfect.

### 4/5 — Кодировка?

*2024-02-27*

С русскими буквами вообще не работает. Компилятор странный, но терпимый вполне.

### 1/5 — Не распознаёт русский язык.

*2024-02-13*

Что это за компилятор, который не распознаёт русский язык? Я имею ввиду в переменных типа string или char вместо русских букв знаки вопроса.

### 3/5 — I lost all of my progress!

*2023-04-10*

This app is good if you have no other options, but I have lost all of my progress in coding a script because it replaced the data of my file with another file. BE CAREFUL WHEN SWITCHING BETWEEN FILES! ALWAYS SAVE YOUR CODE SOMEWHERE ELSE JUST IN CASE!

### 4/5 — 🤭

*2022-04-18*

Игра хорошая но надо добавить русского языка а так всё хорошо.Добавьте пожалуйста Русского языка

### 4/5 — Некоторые вещички ему не подвластны

*2022-01-10*

Главным минусом является наличие подключения к интернету, а так все устраивает.

### 1/5 — ..why are there ads

*2020-09-08, version 1.6*

Seriously. There is no damn reason for this to have ads. I’m uninstalling this.

### 4/5 — Good for fun but high frequency of ads

*2020-08-29*

It’s a good app. It does what it’s supposed to do. It’s nice to program for fun but the ads r too high, like every 5 minutes. I get u need to make money, but seems excessive and a bit greedy. Other than it’s nice
