C Sharp Programming at Wikibooks. C# ( / ˌsiː ˈʃɑːrp / 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 ...
Better codegen for compiler-generated side-effect-free property getters; ARM64 platform-specific compiler and ARM64 target support in F# compiler. Dependency manager #r caching support; Parallel type-checking and project-checking support (experimental, can be enabled via VS setting, or by tooling authors) Miscellaneous bugfixes and improvements ...
C# and VB.NET are syntactically very different languages with very different histories. As the name suggests, the C# syntax is based on the core C programming language originally developed by Dennis Ritchie at Bell Labs (AT&T) in the 1970s. [1] Java and C++ are two other programming languages whose syntax is also based on the C syntax, [2] so ...
.NET Compiler Platform, also known by its codename Roslyn, 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.
Notes Ref Janus — Windows & MS-DOS 5 Combined bundle of Windows 3.1 and MS-DOS 5. Janus is a Roman god usually depicted with two faces, here symbolizing the previously separate Windows and MS-DOS products. Jastro — Windows & MS-DOS 6 Combined bundle of Windows 3.1 and MS-DOS 6. Portmanteau of Janus and Astro, the codename of MS-DOS 6.
Note that the accessor's modifiers can only be equal or more restrictive than the property's modifier. Automatic properties This is a feature of C# 3.0. A feature of C# 3.0 is auto-implemented properties. You define accessors without bodies and the compiler will generate a backing field and the necessary code for the accessors.
C# has a static class syntax (not to be confused with static inner classes in Java), which restricts a class to only contain static methods. C# 3.0 introduces extension methods to allow users to statically add a method to a type (e.g., allowing foo.bar() where bar() can be an imported extension method working on the type of foo).
