After Novell was acquired by Attachmate in April 2011, Attachmate announced hundreds of layoffs for the Novell workforce, putting in question the future of Mono. On May 16, 2011, Miguel de Icaza announced in his blog that Mono would continue to be supported by Xamarin ,
344-434: A handful of objects are long-term objects that live for the entire life of the application. To improve performance this collector assigns memory pools to each thread to let threads allocate new memory blocks without having to coordinate with other threads. Migration of objects from the nursery to the old generation is done by copying the data from the nursery to the old generation pool and updating any live pointers that point to
387-473: A namespace by placing elements inside a namespace block. Assemblies are the physical packaging of the class libraries. These are .dll files, just like (but not to be confused with) Win32 shared libraries. Examples of assemblies are mscorlib.dll, System.dll, System.Data.dll and Accessibility.dll. Namespaces are often distributed among several assemblies and one assembly can be composed of several files. The Common Language Infrastructure (CLI) as implemented by
430-578: A runtime environment that allows multiple high-level languages to be used on different computer platforms without being rewritten for specific architectures. This implies it is platform agnostic. The .NET Framework , .NET and Mono are implementations of the CLI. The metadata format is also used to specify the API definitions exposed by the Windows Runtime . Among other things, the CLI specification describes

#1732845166603516-524: Is a library that allows developers to create C# and .NET based applications that run on the iPhone, iPod and iPad devices. It is based on the Mono framework and developed in conjunction with Novell. Unlike Mono applications, Xamarin.iOS "Apps" are compiled down to machine code targeted specifically at the Apple iPhone and iPad . This is necessary because the iOS kernel prevents just-in-time compilers from executing on
559-440: Is a proprietary implementation of Mono for Android -based smart-phones. It was first released on April 6, 2011. Mono for Android was developed to allow developers to more easily write cross-platform applications that will run on all mobile platforms. In an interview with H-Online, Miguel de Icaza stated, "Our vision is to allow developers to reuse their engine and business logic code across all mobile platforms and swapping out
602-516: Is common for RAND licensing to require some royalty payment, which could be a cause for concern with Mono . As of January 2013 , neither Microsoft nor its partners have identified any patents essential to CLI implementations subject to RAND terms. As of July 2009 , Microsoft added C# and CLI to the list of specifications that the Microsoft Community Promise applies to, so anyone can safely implement specified editions of

Mono has innovated in some areas with new extensions to the core C# and CLI specifications: In addition, Mono is available on a variety of operating systems and architectures. Windows 7, Windows 8, Windows 8.1, Windows 10, macOS or Linux Several projects extend Mono and allow developers to use it in their development environment. These projects include: Cross-platform: macOS: Mobile platforms: Windows: Microsoft has
731-537: Is structured into namespaces, and deployed in shared libraries known as assemblies. Speaking of the .NET Framework is primarily referring to this class library. Namespaces are a mechanism for logically grouping similar classes into a hierarchical structure. This prevents naming conflicts. The structure is implemented using dot-separated words, where the most common top-level namespace is System, such as System.IO and System.Net. There are other top-level namespaces as well, such as Accessibility and Windows. A user can define
774-405: Is useful for high performance computing loads and other situations where the execution performance is more important than the startup performance. Starting with the Mono 2.7 preview, it is no longer necessary to pick one engine over the other at configuration time. The code generation engine can be selected at startup by using the --llvm or --nollvm command line arguments, and it defaults to
817-535: The Common Language Runtime (CLR) , is implemented by the Mono executable. The runtime compiles and executes .NET applications. The common language infrastructure is defined by the ECMA standard. To run an application, you must invoke the runtime with the relevant parameters. The Common Language Specification (CLS) is specified in chapter 6 of ECMA-335 and defines the interface to the CLI, such as conventions like
860-492: The Microsoft Community Promise Agreement." The Xamarin.Android stack consists of the following components: Common Language Infrastructure The Common Language Infrastructure ( CLI ) is an open specification and technical standard originally developed by Microsoft and standardized by ISO / IEC ( ISO/IEC 23271 ) and Ecma International ( ECMA 335 ) that describes executable code and

1032-524: The data to point to the new location. This can be expensive for large objects, so Mono's SGen uses a separate pool of memory for large objects (Large Object Section) and uses a mark-and-sweep algorithm for those objects. The class library provides a comprehensive set of facilities for application development. They are primarily written in C#, but due to the Common Language Specification they can be used by any .NET language. The class library
1075-413: The default collector in version 3.1.1. The SGen garbage collector has many advantages over a traditional conservative scanner. It uses generational garbage collection where new objects are allocated from a nursery, during the garbage collection cycle, all objects that survived are migrated to an older generation memory pool. The idea is that many objects are transient and can quickly be collected and only

From April to early September 2010, the future of MonoTouch was put in doubt as Apple introduced new terms for iPhone developers that apparently prohibits them from developing in languages other than C, C++ and Objective-C , and
1161-417: The distribution. Windows Forms 2.0 is also supported, but not actively developed, and as such its support on Mono is incomplete. Version 4.0 was the first version that incorporates Microsoft original source code that was released by Microsoft as part of the .NET Core project. As of January 14, 2021, Mono has full support for all the features in .NET 4.7 except Windows Presentation Foundation (WPF) (which

1333-744: The fast-starting Mono code generation engine. Starting with Mono 5.18, support for LLVM is a default configuration option. Previous versions required a special LLVM fork, but now mono can fall back to its own code generator when it encounters something not handled by LLVM. As of Mono 2.8, the Mono runtime ships with two garbage collectors : a generational collector and the Boehm–Demers–Weiser Conservative Garbage Collector . The Boehm garbage collector could exhibit memory leaks on certain classes of applications, making it unsuitable for some long-running server applications. Mono switched to Simple Generational GC (SGen-GC) as

1591-427: The standards without fearing a patent lawsuit from Microsoft. To implement the CLI standard requires conformance to one of the supported and defined profiles of the standard, the minimum of which is the kernel profile. The kernel profile is actually a very small set of types to support in comparison to the well known core library of default .NET installations. However, the conformance clause of the CLI allows for extending
1634-494: The supported profile by adding new methods and types to classes, as well as deriving from new namespaces. But it does not allow for adding new members to interfaces. This means that the features of the CLI can be used and extended, as long as the conforming profile implementation does not change the behavior of a program intended to run on that profile, while allowing for unspecified behavior from programs written specifically for that implementation. In 2012, Ecma and ISO/IEC published
1677-591: The underlying types for Enum. The Mono compiler generates an image that conforms to the CLS. This is the Common Intermediate Language. The Mono runtime takes this image and runs it. The ECMA standard formally defines a library that conforms to the CLS as a framework. Within a native .NET/Mono application, all code is managed ; that is, it is governed by the CLI's style of memory management and thread safety. Other .NET or Mono applications can use legacy code, which
