It has language structures that explicitly support these features, making it a natural language for creating and deploying software components. C# has evolved to accommodate new workloads and innovative software design techniques since its inception.
C# Development Features
Several C# features, such as the ones listed below, aid in the development of robust applications.
Automatically reclaims memory that was previously taken by inaccessible unused objects.
Avoid variables that do not relate to allocated objects.
A systematic and extendable method to error detection and recovery is provided.
Functional programming approaches are supported.
Language Integrated Query (LINQ) syntax
Makes a reusable pattern for interacting with data from any source.
The syntax for creating distributed systems is provided by language support for asynchronous operations.
C# Development Type System
C# features a type system that is uniform. All C# types, including simple types like int and double, derive from a single root object type.
A collection of common operations is shared by all types. Values of any sort can be consistently stored, transferred, and operated on.
C# also allows user-defined reference types and value types. It supports dynamic object allocation and in-line storing of lightweight structures. C# includes generic methods and types, which improve type safety and performance. Iterators in C# allow collection class implementers to provide specific behavior for client applications.
C# also stresses versioning to guarantee that applications and libraries may change in a compatible way over time.
The distinct virtual and override modifiers, the rules for method overload resolution, and support for explicit interface member declarations are all aspects of C#'s design that were directly impacted by versioning considerations.
C# Programming and .NET Architecture
C# applications are executed using .NET, a virtual execution system known as the common language runtime (CLR), and a collection of class libraries. The CLR is Microsoft's implementation of the international standard common language infrastructure (CLI).
The CLI serves as the foundation for establishing execution and development environments in which languages and libraries can be used at the same time.
C# source code is compiled into an intermediate language (IL) that adheres to the CLI standard. The IL code and resources, like bitmaps and strings, are generally saved in an assembly with a .dll extension. A manifest in an assembly contains information about the assembly's types, version, and culture.
The assembly is loaded into the CLR when the C# program is run. Just-In-Time (JIT) compilation is used by the CLR to transform IL code to native machine instructions.
Other services provided by the CLR include automated garbage collection, exception handling, and resource management. The CLR-executed code is sometimes referred to as "managed code." "Unmanaged code" is compiled into native machine language that is platform-specific.
