This document discusses platform independent integrated development environments (IDEs) for CSharp. A platform independent IDE is designed to develop software that can run on any operating system without being specific to one. The document lists some offline platform independent IDEs for CSharp development, including MonoDevelop, Emonic, and SharpDevelop. It also lists some online C# compilers.

1. Platform independent IDEs for CSharp
With platform independent IDEs for CSharp, an
independent to platform or platform independent or
PIM ,in programming world, is a model designed for the
development of software for business or personal use, is a
model that can be used in any platform or non specific to
a particular platform such as Windows,Linux,Solaris etc.
This model is most often utilized as a part of the platform
free framework that not only supports operating systems
but also the different hardware such as intel, AMD, Sun
Micro Framework and so forth. This type of design
methodology relates to the Model Driven Engineering.
Things that are kept in mind before selecting an IDE
Before selecting an independent platform for C#, one
thing should be kept in mind that it is a third-party tool ,
not that from Microsoft. Any latest Microsoft version or
new concept may not be supported.
Given below are some very good platforms for C#
applications development:

2. Offline platforms
1.MonoDevelop:
Company claims
MonoDevelop enables developers to quickly write desktop
and web applications on Linux, Windows and Mac OS X. It
also makes it easy for developers to port .NET
applications created with Visual Studio to Linux and Mac
OS X maintaining a single code base for all platforms.

2.Emonic
Company claims
Emonic (Eclipse-Mono-Integration) is a Eclipse-Plugin for
C#. It provides color-highlighting, outline, word-
completion and build mechanism via Ant or Nant. Tested
on Linux and Windows with Mono and the Win-.net-
framework.

3.SharpDevelop
Company claims:
#develop (short for SharpDevelop) is a free IDE for C#,
VB.NET and Boo projects on Microsoft’s .NET platform. It
is open-source, and you can download both sourcecode
and executables from this site. In addition, you can find
the latest information and changes on #develop, as well
as get in touch with the team in the forum.
