When contributing to the Mono project, please follow the [Mono Coding Guidelines][1]. We have been using a coding style for many years, please make your patches conform to these guidelines.
[1] http://www.mono-project.com/Coding_Guidelines
In general, we do not accept patches that merely shuffle code around, split classes in multiple files, reindent the code or are the result of running a refactoring tool on the source code. This is done for three reasons: (a) we have our own coding guidelines; (b) Some modules are imported from upstream sources and we want to respect their coding guidelines and (c) it destroys valuable history that is often used to investigate bugs, regressions and problems.
The Mono project uses the MIT X11, GNU LGPL version 2 and the Apache License 2.0. We also imported some Microsoft code licensed under the open source Microsoft Public License.
Different parts of Mono use different licenses. The actual details of which licenses are used for which parts are detailed on the LICENSE file in this directory.
When contributing code, make sure that your contribution falls under the appropriate license. For example, contributions to code licensed under MIT X11 code, should be MIT X11 code.
The Runtime is a special case. The code is dual licensed by Xamarin under both the GNU LGPL v2 license and is also available under commercial terms. For the runtime, you should either sign an agreement that grants Xamarin the rights to relicense your code under other licenses other than the LGPL v2 or your contribution must be made as an MIT X11 license which grants us the same rights, but involves no paperwork.
When Submitting patches to the dual-licensed portions, please specify on the commit the license that the code is under.
