Mono C# 2.0 and C# 3.0 compiler for CLI 2.0 This is the Mono C# (C-Sharp) 2.0 and C# 3.0 compiler, a platform-independent compiler which produces CIL (Common Intermediate Language) binary executables. The gmcs compiler supports two different featuresets (C# versions). With C# 2.0 (which is the default) it supports: - generics - iterators (yield) - nullable value types - partial types - anonymous methods - static classes - coalesce operator: ?? With C# 3.0 it supports: - Language Integrated Query (LINQ) - object initializers - collection initializers - anonymous types - local variable type inference - implicitly-typed arrays - lambda expressions - automatic properties - extension methods - partial methods This compiler targets the CLI 2.0 runtime version. Mono is a platform for running and developing applications based on the ECMA/ISO Standards. Mono is an open source effort led by Novell. Mono provides a complete CLR (Common Language Runtime) including compiler and runtime, which can produce and execute CIL (Common Intermediate Language) bytecode (aka assemblies), and a class library.
