Mono 是一个由Novell 公司主持的项目。该项目的目标是创建一系列符合ECMA 标准（Ecma-334 和Ecma-335）的.NET 工具，包括C# 编译器和共通语言执行平台。与微软的.NET Framework 不同，Mono 项目不仅可以运行于Windows 系统上，还可以运行于Linux，FreeBSD，Unix，Mac OS X 和Solaris。
Mono 的开发工具 MonoDevelop
微软开发了一个称为共享源码公共语言基础（Shared Source Common Language Infrastructure，Shared Source CLI）的可用于 FreeBSD，Windows 和 Mac OS X 的 .NET 实现版本。微软的共享源码协议并不是开源软件协议，且可能对于社区来说也是不足够的（它明文禁止了对软件的商业用途）。我们还可以见到另外一个 .NET 实现版本，Portable.NET 项目，该项目与 Mono 项目有着很多相同的目标。
Mono 虚拟机包含一个实时编译引擎，该引擎可用于如下处理器：x86，SPARC，PowerPC，ARM，S390（32位模式和64位模式），x86-64，IA64 和64位模式的 SPARC。该虚拟机可以将代码实时编译或者预先编译到原生代码。对于那些没有列出来的系统，则使用的是代码解释器。

Mono 3.6 发布，此版本从上一个版本开始，包括了 878 个 commits，从 2014 年 3 月 10 日开始，就有 66 位贡献者参与开发，修复了 112 个 bug。
值得关注的更新
Runtime performance counters have been integrated into the profiler.
The profiler now produces backtrace for statistical mode. tracing mode now works on arm.
Big refactoring on the class library build. We’re now much closer to having it build on windows without cygwin.
We now distribute nuget on mac.
调试器
It now support line and column ranges. pdb2mdb supports it.
It now supports for changing the current line in the top frame.
Lots of bugfixes and performance improvements.
The debugger now support reading simple properties without calling their getter.
Added buffered response mode to improve network efficiency on high latency links such as USB.
GC
The GC bridge got a lot of performance work. There are now two new modes that can significantly improve some workloads.
类库
Multiple http stack improvements.
System.IO.Compression is now implemented
System.Security.Claims
性能
Reworked locking to drop a hot lock in method lookup.
Use fine grained locking instead of a big hot lock.
Better hashing of some runtime internal items to avoid some corner-case slowdowns with generics.
配置器
It now produces backtraces in statistical mode.
Added periodical flushing that should help interactive users.
It now collects and reports performance counter information. See mprof-report.
Misc
Fixed the handling of the volatile. CIL prefix.
We now distribute ikdasm
Optimized EqualityComparer for more types.
Mono.Unix.Native.Syscall.getxattr() can now return Errno.ENOATTR on OS X.
Our msbuild implementation can now build Project K and Roslyn
