C# (pronounced see sharp) is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed by Microsoft within its .NET initiative and later approved as a standard by Ecma and ISO. C# is one of the programming languages designed for the Common Language Infrastructure.

C# is intended to be a simple, modern, general-purpose, object-oriented programming language. Its development team leader is Anders Hejlsberg. The most recent version is C# 4.0, which was released on April 12, 2010.

The name "C sharp" was inspired by musical notation where a sharp indicates that the written note should be made a semitone higher in pitch. This is similar to the language name of C++, where "++" indicates that a variable should be incremented by 1.

Due to technical limitations of display (standard fonts, browsers, etc.) and the fact that the sharp symbol (# music sharp sign) is not present on the standard keyboard, the number sign was chosen to represent the sharp symbol in the written name of the programming language. This convention is reflected in the ECMA-334 C# Language Specification. However, when it is practical to do so (for example, in advertising or in box art), Microsoft uses the intended musical symbol.

The "sharp" suffix has been used by a number of other .NET languages that are variants of existing languages, including J# (a .NET language also designed by Microsoft that is derived from Java 1.1), A# (from Ada), and the functional programming language F#. The original implementation of Eiffel for .NET was called Eiffel#, a name since retired since the full Eiffel language is now supported. The suffix has also been used for libraries, such as Gtk# (a .NET wrapper for GTK+ and other GNOME libraries), Cocoa# (a wrapper for Cocoa) and Qt# (a .NET language binding for the Qt toolkit).

Worth every penny

I wanted to make sure that this get what it deserves. Making a free app with no ads that is as nice and complete as this deserves be paid for. The developer will only be able to continue to make apps like this if they can get paid while doing it. This app is exactly what I was looking for in learning C# on the go. $2.99 for unlimited compilations is a bargain and all those complaining just don’t understand how development works. If some builds something and they use there own time and effort, they should be able to ask for compensation.

The only thing I wish it had was iPad Shortcuts. Would be great run, build, and compile using a keyboard shortcut instead of having to reach up every time. Not a huge thing just a hopeful want for the future.

Ignore 1 Stars

When I saw the reviews I was expecting some money grabbing app. The people writing these 1 star reviews are obviously kids who think $3 is breaking the bank. You can pay $1 for 100 compiles or pay $3 for unlimited. The app even has a restore option so you can reinstall or install on another device.

Now my review. I don't use this as my main way of writing programs, but it is a great option for while I'm on the go. It's better than other apps I've tried and definitely better than remoting into a PC.

+Fare Compile fee

Mobile C# that works

It works! And just because you have to pay a few bucks for unlimited compiles does not warrant negative reviews. I use this app to sketch out C# tidbits that I later flush out on my laptop.
