The programming language C# version 3.0 was released on 19 November 2007 as part of .NET Framework 3.5.It includes new features inspired by functional programming languages such as Haskell and ML, and is driven largely by the introduction of the Language Integrated Query (LINQ) pattern to the Common Language Runtime. [1]
C# (/ ˌ s iː ˈ ʃ ɑːr p / see SHARP) [b] is a general-purpose high-level programming language supporting multiple paradigms.C# encompasses static typing, [16]: 4 strong typing, lexically scoped, imperative, declarative, functional, generic, [16]: 22 object-oriented (class-based), and component-oriented programming disciplines.
.NET Compiler Platform, also known by its codename Roslyn, [2] is a set of open-source compilers and code analysis APIs for C# and Visual Basic (VB.NET) languages from Microsoft. [ 3 ] The project notably includes self-hosting versions of the C# and VB.NET compilers – compilers written in the languages themselves.
C# 3.0 introduced type inference, allowing the type specifier of a variable declaration to be replaced by the keyword var, if its actual type can be statically determined from the initializer. This reduces repetition, especially for types with multiple generic type-parameters , and adheres more closely to the DRY principle.
Generics, or parameterized types, or parametric polymorphism is a .NET 2.0 feature supported by C# and Visual Basic. Unlike C++ templates, .NET parameterized types are instantiated at runtime rather than by the compiler; hence they can be cross-language whereas C++ templates cannot.
LLVM can accept the IR from the GNU Compiler Collection (GCC) toolchain, allowing it to be used with a wide array of extant compiler front-ends written for that project. LLVM can also be built with gcc after version 7.5. [37] LLVM can also generate relocatable machine code at compile-time or link-time or even binary machine code at runtime.
Code became "portable" due to the compiler, and in fact, both Visual Basic .NET and C# use the same CLR (Common Language Runtime) today. Microsoft and HP were interested in creating an ISO standard language, which was the original goal, however; HP dropped its support, and the ISO computer language never materialized as an International Standard.
The CLR is an interpreter rather than a just-in-time compiler, and uses a simpler mark-and-sweep garbage collector instead of a generational method. An ahead-of-time compiler is being developed [5] using a modified LLVM compiler. Interoperation between managed and native code currently has several limitations.
