As a precursor to the lambda functions introduced in C# 3.0, C#2.0 added anonymous delegates. These provide closure-like functionality to C#. [3] Code inside the body of an anonymous delegate has full read/write access to local variables, method parameters, and class members in scope of the delegate, excepting out and ref parameters. For example:-
Anders Hejlsberg (/ ˈ h aɪ l z b ɜːr ɡ /, born 2 December 1960) [2] is a Danish software engineer who co-designed several programming languages and development tools. He was the original author of Turbo Pascal and the chief architect of Delphi.
Simula, invented in the late 1960s by Nygaard and Dahl as a superset of ALGOL 60, was the first language designed to support object-oriented programming. FORTH , the earliest concatenative programming language was designed by Charles Moore in 1969 as a personal development system while at the National Radio Astronomy Observatory (NRAO).
WPF employs XAML, an XML-based language, to define and link various interface elements, and uses C# to define program behavior. [4] WPF applications are deployed as standalone desktop programs. WPF supports a number of common user interface elements, such as 2D/3D rendering, fixed and adaptive documents , typography , vector graphics , runtime ...
The Java language has provided genericity facilities syntactically based on C++'s since the introduction of Java Platform, Standard Edition (J2SE) 5.0. C# 2.0, Oxygene 1.5 (formerly Chrome) and Visual Basic (.NET) 2005 have constructs that exploit the support for generics present in Microsoft .NET Framework since version 2.0.
The language is specific to a particular processor family and environment. [2] Second-generation languages are sometimes used for parts of kernels or device drivers, and are sometimes used in video games, graphics programs, and other intensive programs. [1] In modern programs, second generation assembly languages are rarely used. [5]
