.NET vs C# – Difference and Comparison

What is .NET?

.NET is a programming language that is used for constructing web-based and form-based applications, as well as online services. It can develop programs for mobile devices, the web, and Windows. It has been determined to be the most productive platform available. It is compatible with any app and on any platform.

.NET is a cutting-edge approach to application development that is ranked first globally. This framework specifies the rules and supporting libraries that languages must follow to function properly.

Mobile, web, & Windows-based programs can all benefit from the guidelines for programmers. It is compatible with more than 60 programming languages, including C++, VB.NET, F#, and C#. Microsoft has developed 11 programming languages among the more than 60 available.

To run.NET assemblies, the CLI (common language runtime) must be installed on your computer, which may be done using the command-line interface (CLI).

Using the FCL and the CLR, this framework makes it easier to communicate across networks and access data, construct web applications, implement cryptography and user interfaces, and implement numerical algorithms.

There have been several different versions of.NET released. The most recent version is 4.7.2. Designing and developing.NET apps require using a programming tool known as Visual Studio, available for free download.

Previous to this,.NET was included in the installation media for operating systems and the installation media for other applications. Because of this, higher versions (3.5 and later) must be downloaded and installed over the Internet or through Microsoft Windows installation discs.

One of the advantages of.NET is that it is reusable designed, and this means that adding or removing functionality is a simple process. Because it is cross-platform, it can be used in many languages, and it is simple to put into action.

What is C#?

For example, Boolean conditions and conditional compilation are among the features available in C#. Other features include easy-to-use generics, assembly versioning, and an integrated standard library. Other features include simple multithreading and delegates management, events management, and indexers.

Microsoft.NET developers prefer to work in C#, their programming language of choice. Unlike C++ and Java, C# is much easier to learn. Several projects and applications can be developed because of their high flexibility. A modest amount of keywords are used to construct the system’s structure. A non-.NET platform version of C# can be used with an open-source version of the Common Language Runtime (CLR).

Because C# does not involve type conversion, there is no risk of lost data. The non-nullable and non-able types are both supported by Ctype #’s system.

Mobile applications, cloud-based services, enterprise software, websites, desktop applications, and games are all programs and applications developed using C#. This is the eighth version of C#.

C# has several drawbacks, including case sensitivity (which can cause code confusion), and it’s entirely built on Microsoft’s. NET framework, limiting its versatility.

Difference Between .NET and C#

  1. When it comes to the.NET platform, C# is the programming language of choice.
  2. While the Microsoft Developer Network (MSDN) community is extremely supportive of C#, the Microsoft Developer Network (MSDN) and the IBM network community are quite supportive of.NET.
  3. The.Net framework allows for the automated initialization of local variables, but, in C#, this is not possible for a variable that is part of a process.
  4. Even if a function named “My base. New” cannot be used in C#, it can be used in the.Net framework to invoke the function Object() { [native code] } of a specific base class from a derived class.
  5. In C#, it is possible to use both checked & unchecked functions for verification, although this capability is not supported by the.NET framework.

Comparison Between .NET and C#

Parameters of Comparison.NETC#
DefinitionOpen-source developers can use the.NET framework.It is a free and open-source object-oriented programming language.
CompatibilityWindows is the only platform on which Microsoft’s. NET framework is available, but.NET itself can operate on any platform.In addition to Windows, C# is supported on additional operating systems.
ImplementationFor inheritance, the.NET framework follows the single implementation inheritance paradigm. As a result, in.NET, a single class can implement a variety of phase transitions.The basic interface may be constructed using a class to specify the method’s attributes, events, and indices.
ArchitectureIn the class library of the.NET framework, you’ll find Ado.net, Windows Forms, and, most notably, Asp. This means that the libraries can be applied to various software development projects.The.NET framework serves as the foundation for the C# programming language. An execution system is known as CLR, and a set of class libraries enhance its programs.
FunctionalityIn addition to C#,.NET works with other languages.The.NET framework includes C# as one of its components.
UsageMicrosoft-based programs make extensive use of this technology.Desktop-based apps are the principal use of C#.
