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.
Microsoft's 32-bit Structured Exception Handling (SEH) uses this approach with a separate exception stack. [20] Dynamic registration, being fairly straightforward to define, is amenable to proof of correctness. [21] The second scheme, and the one implemented in many production-quality C++ compilers and 64-bit Microsoft SEH, is a table-driven ...
SEH on 64-bit Windows does not involve a runtime exception handler list; instead, it uses a stack unwinding table (UNWIND_INFO) interpreted by the system when an exception occurs. [4] [5] This means that the compiler does not have to generate extra code to manually perform stack unwinding and to call exception handlers appropriately. It merely ...
The first hardware exception handling was found in the UNIVAC I from 1951. Arithmetic overflow executed two instructions at address 0 which could transfer control or fix up the result. [16] Software exception handling developed in the 1960s and 1970s. Exception handling was subsequently widely adopted by many programming languages from the ...
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.
Starting with the 2005 edition, Visual Studio also added extensive 64-bit support. While the host development environment itself is only available as a 32-bit application, Visual C++ 2005 supports compiling for x86-64 (AMD64 and Intel 64) as well as IA-64 . [135] The Platform SDK included 64-bit compilers and 64-bit versions of the libraries.
The code name "Roslyn" was first written by Eric Lippert (a former Microsoft engineer [5]) in a post [6] that he published in 2010 to hire developers for a new project. He first said that the origin of the name was because of Roslyn, Washington, but later in the post he speaks ironically about the "northern exposure" of its office; the city of Roslyn was one of the places where the television ...
