C# versus C++

Although it has some elements derived from Visual Basic and Java, C++ is C#'s closest relative. In an important change from C++, C# code does not require header files. All code is written inline. As touched on above, the .NET runtime in which C# runs performs memory management, taking care of tasks like garbage collection. Because of this, the use of pointers in C# is much less important than in C++. Pointers can be used in C#, where the code is marked as 'unsafe', but they are only really useful in situations where performance gains...

C# versus Java

C# and Java are both new-generation languages descended from a line including C and C++. Each includes advanced features, like garbage collection, which remove some of the low level maintenance tasks from the programmer. In a lot of areas they are syntactically similar.   Both C# and Java compile initially to an intermediate language: C# to Microsoft Intermediate Language (MSIL), and Java to Java bytecode. In each case the intermediate language can be run - by interpretation or just-in-time compilation on an appropriate 'virtual...

The CLI describes the features that each language must provide in order to use the .NET Framework and comm6n language runtime and to interoperate with components written in other languages. If a language implements the necessary functionality,...

What is Garbage Collection

When you initialize a variable using the new operator, you are in fact asking the compiler to provide you some memory space in the heap memory. The compiler is said to "allocate" memory for your variable. When that variable is no longer needed, such as when your program closes, it (the variable) must be removed from memory and the space it was using can be made available to other variables or other programs. This is referred to as garbage collection. In the past, namely in C/C++, this was a concern for programmers because they usually ...

What is Common Language Infrastructure (CLI)

The Common Language Infrastructure (CLI) is an open specification developed by Microsoft that describes the executable code and runtime environment that allows multiple high-level languages to be used on different computer platforms without being rewritten for specific architectures. CLR is Microsoft Commercial implementation of Common Language Infrastructure (CLI). The Common Language Infrastructure (CLI) is a theoretical model of a development platform that provides a device and language independent way to express data and behavior...

What is Just in Time Compiler(JIT)

Machines cannot run MSIL directly. JIT compiler turns MSIL into native code, which is CPU specific code that runs on the same computer architecture as the JIT compiler. Because the common. Language runtime supplies a JIT compiler for each supported CPU architecture, developers can write a set of MSIL that can be JIT-compiled and run on computers with different architectures. However, your managed code will run only on a specific operating system if it calls platform specific native APIs, or a platform-specific class library. JIT compilation...

What is Visual Studio .NET

The following is the list of some of the features of Visual Studio .NET:   1. Visual studio automates the step required to compile source code.   2. The Visual Studio text editor is very intelligent; it can detect errors and suggests code as appropriate as you required.   3. The Visual Studio designer for Windows Forms and Web Forms applications, allowing simple Drag and drop design of User Interface elements.   4. The Visual Studio contains many powerful tools for visualizing and navigating through the...

What is Common Type System (CTS)

The language interoperability, and .NET Class Framework, are not possible without all the language sharing the same data types. What this means is that an "int" should mean the same in VB, VC++, C# and all other .NET compliant languages. Same idea follows for all the other data types. This is achieved through introduction of Common Type System (CTS). Common type system (CTS) is an important part of the runtimes support for cross language integration. The common type system performs the following functions: • Establishes a framework...

What is Microsoft Intermediate Language (MSIL)

A .NET programming language (C#, VB.NET, J# etc.) does not compile into executable code; instead it compiles into an intermediate code called Microsoft Intermediate Language (MSIL). As a programmer one need not worry about the syntax of MSIL - since our source code in automatically converted to MSIL. The MSIL code is then send to the CLR (Common Language Runtime) that converts the code to machine language which is then run on the host machine. MSIL is similar to Java Byte code. A Java program is compiled into Java Byte code (the...
