Mono 跨平台的 .NET 运行环境

Mono是一个由Novell公司(由Ximian发起，并由Miguel de lcaza领导的，一个致力于开创.NET在Linux上使用的开源工程。它包含了一个C#语言的编译器，一个CLR的运行时，和一组类库，并实现了 ADO NET和ASP NET。能够使得开发人员在Linux用C#开发程序。)主持的项目.该项目的目标是创建一系列符合标准ECMA (Ecma-334和Ecma-335)的.Net 工具, 包括C #编译器和共同语言(CL 即 Common Language)执行平台(Platform).与微软的.Net不同, Mono项目不仅可以运行于Windows系统内,还可以运行于Linux, FreeBSD, Unix, Mac OS X和Solaris。

值得关注的更新：

• 整个运行时的重要性能提升和伸缩性性改进

• 完成对 Windows 64 位的支持

• usb 连接的调试器有线协议优化

在调试器方面：

• Updated wire protocol better handles high latency connections such as those found when doing USB debugging.

• Client library now aggressively caches information and batches requests. Under one test scenario single stepping packets transmitted dropped from 2233 to only 16, which the latency going from seconds to 20 milliseconds.

性能：

• The JIT now better handle long remainders by powers of two, generating significantly better code.

• Over 10x faster code is generated for delegates that only invoked once. C# features such as async and LINQ produces a lot of those delegates, so this improvement will impact everyone.

• Improved alias analysis can now handle second order aliases and eliminate null checks.

• The runtime now has a concurrently readable hashtable that can makes reflection heavy workloads significantly faster and more scalable.

垃圾回收：

• Optimized one of the core data structures of the garbage collector should result in 5 to 10% reduction in collection times.

Bug 修复：

运行时：

• Fix the leaking of mach ports introduced by 98bbf8512aec0fa01b4426583280f6d231d22187. Fixes #22068

• When parsing a method header, ensure we pass any available generic context. Fixes #21388

• Added new mono_domain_set_config function; used to fix ConfigurationErrorsException in #10468

• Explicit thread GC data around instead of relying on TLS storage. Fixes #20360

• Make WaitForPendingFinalizers () really wait for the finalizers added by a previous GC. Fixes #20503

• Fix the marshal7.cs test, longs can be aligned to 4 bytes on 32 bit linux, and the runtime no longer aligns structure sizes to 8 bytes. Fixes #20788

• Fix the popping of LMF frames during unwinding. Fixes #20616

• Fix the marshalling of ByValTStr types which have a size specified. Fixes #20674

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。
