General Help

These are pages with general help on developing applications for .NET and Mono, and other topics not specific to boo itself but useful for a boo developer.

General Info about .NET and Mono

.NET is Microsoft's application framework and runtime engine. Most people using Windows XP have .NET version 1.1, but the 2.0 version was released in the fall of 2005. Boo now supports .NET 4.0.

There is also an open source clone of .NET called Mono, that runs on Linux, Mac OS X, and Windows. It is derived from the open Common Language Infrastructure (CLI) specification used by .NET.

Below are some resources for developing .NET/Mono applications (primarily the open source and free resources), as well as tutorials.

IDEs - Integrated Development Environments

  • (lightbulb)SharpDevelop - free, open source, includes a forms designer/GUI builder. Windows only. SharpDevelop supports boo fully.
  • MonoDevelop - Works with Mono on Linux or Mac. Peter Johanson has created a boo add-in for MonoDevelop.
  • Nant - an XML-based build tool based on Java's ant build tool. Used to build boo itself.
  • Visual Studio 2010 (and there is a free Express version of VS 2010 too). The standard commercial IDE used on Windows. People are interested in creating a boo plugin for VS.
  • Monolipse There is a boo addin for Eclipse called monolipse. monolipse originated as another project named booclipse but has been expanded to support other EMCA languages such as C#.
  • SciBoo - by Steve Donovan, a ScintillaNET based editor.
  • Smulton - by Peter Borg. A Mac OS X text editor. An add-in for Boo support is authored by Grant Morgan from the team. With the Smultron command window you can automatically execute your boo code without leaving the editor.

Web Development

See the ASP.NET page and tutorials.

ASP.NET is the standard, but see also:

Developing Desktop GUI Applications


The standard Windows API, but you can call it from Linux as well, using Mono's Managed.Windows.Forms project. Here are some code snippets and tutorials on using Windows.Forms:

The easiest way to create windows forms with boo is to use SharpDevelop. It has a form designer with support for boo, if you use the new version. If you use an older version or another C# form designer, you can convert the C# generated code to boo automatically.


GTK# is the GUI API used in the GNOME project for Linux, but you can use it on Windows and Mac OS X too, see these articles:

GTK# on Windows

There are two versions of GTK# that run on Windows.

  • One runs in .NET 1.1 (here is the installer)
  • the other runs in Mono, and is included in the combined Mono installer for Windows.

Note though, to compile apps that use the GTK# runtime for .NET 1.1, you may need to download the .NET 1.1 SDK to get them to compile.

Another item now available on Windows is the Gecko Runtime Engine (GRE, here is the installer). This lets you embed the Mozilla browser engine in your GTK# app as a WebControl.

WX.NET and QT#


  • ADO.NET - the standard API for working with relational databases, see also Database Recipes and Database Design.
  • Most relational database engines have interfaces to .NET/Mono, such as SQLite, MySQL, MS SQL Server, MS Access, Firebird...
  • The Database Recipes page also shows examples of non-SQL-based database engines such as db4o.

Math / Statistics


3D, Game Development

  • Game Engines
    • RealmForge - OpenGL and DirectX can be used interchangeably
    • Irrlicht - has .NET bindings, can also use OpenGl or DirectX
    • Ovorp - 2D game engine

Please add any game programming tips or samples you have to this site or the boo page at the game programming wiki.


  • IndyProject - networking libs for doing ftp, soap, http, smtp, pop, nntp, etc.
  • Netspell

See also: GnomeFiles for some Mono apps and libs, CSharp-Source for open source .NET libraries and apps, and CodeProject for many useful .NET tutorials and code samples.
