Microsoft consistently invests in its technology stack, allowing developers to build safe and secured software products that enable companies to better serve their customers’ ever-changing needs.
Each software product from Microsoft has a lifecycle. When a product is released, the life cycle starts, and it ends when it is no longer supported. Knowing important dates in this lifecycle might help you decide when to upgrade or make other software changes.

With ASP.NET Web Forms (ASPX) for web applications and ASP.NET Web Service (ASMX) for web services, ASP.NET was first made available in 2002 along with the.NET Framework 1.0.

Web Forms was replaced by ASP.NET MVC when it was introduced in 2009. ASP.NET MVC offered a more minimal layer of abstraction over the web than Web Forms, which attempted to replicate the creation of classic Windows applications.

A complete revamp of ASP.NET is ASP.NET Core which was released in 2016. For more details on important dates for software changes, you can check out Microsoft.

**When to Choose .NET Core Vs .NET Framework Vs ASP.NET for your Project?**

Before implementing any of these technologies into a project, one should take into account the following factors to choose the finest technology:

## Reasons Why Businesses are Choosing .NET Core

The.NET Framework’s “younger brother,”.NET Core, was developed to fill in some of the gaps left by the original.NET Framework. These consist of:

- **Cross-Platform Integration:** 
A cross-platform solution was becoming increasingly necessary in the software development community, therefore Microsoft released .NET Core. The platform enables developers to create apps that can operate on Windows, macOS, and Linux. Microsoft is adding platforms to its list of supported ones. On each of those platforms, developers can use the command line, and when using Windows and macOS, they can take advantage of Visual Studio (in a limited capacity). In addition, Visual Studio Code is cross-platform and works with Windows, Linux, and macOS.

- **Building Microservices: **
Software applications composed of small, modular business services are supported by .NET Core when they are built on a service-oriented architecture. Each of these services typically uses a distinct process developed using various programming languages and is set up independently. This fantastic feature enables owners to scale their applications by quickly adding more microservices. Additionally, .NET Core enables the blending of development tools and can be scaled down for each microservice.

- **Using Docker Containers:** 
Microservices come along with docker containers. Because it is lightweight and modular, .NET Core blends in well with this style of architecture. Additionally, cross-platform deployment directly to dockers is made possible. The.NET Framework can also be used for containers, however, the image size will be much bigger.

- **CLI Control:**
 For developers who prefer working in lightweight editors with the CLI function,.NET Core enables CLI control across all supported platforms, which is particularly appealing. 
Furthermore,.NET Core offers the option of switching to an Integrated Development Environment (e.g., Visual Studio IDE) for easy accessibility and only requires a minimal installation on development platforms.

- **Scaling-up:**
 When you have long-term plans for your tool and anticipate a scale-up, Microsoft advises using.NET Core with ASP.NET Core. This combination provides the best performance and easy scaling. With fewer servers and virtual machines needed, it enables developers to deploy hundreds of microservices. A better user experience and significant cost savings result from this efficiency.

- The .NET Core is best when you: 
- If you want to target various operating systems (create once, run everywhere- Cross-platform compatibility) 
- Require scalability and high performance
- If you prefer open-source
- If you want microservices and docker containers
- If you need support for side-by-side installation

## Reasons Why Businesses are Choosing .NET Framework

- **Platform Independence:** 
Any application type, on any platform, can be built using .NET. It supports all platforms, therefore to put it simply, it is platform-independent. As such, the mobile applications made with .NET will support a variety of operating systems, including Android, iOS, Windows, and others. .NET offers you every solution possible when making apps.

- **Language Support and Easy Deployment:**
 Microsoft supports 60 programming languages. You are allowed to use whatever language you like in your application. The ease of deployment of .NET is also a prime reason developers and companies choose the .NET framework. Resources for application development are provided since it contains library class files.

- **Best Architecture with Easy User Interface: **
.NET Framework uses an IDE (Integrated Development Environment) that is efficient and dynamic when developing applications. You can create an effective application using the best-in-class MVC (Model-View-Controller) architecture, an intuitive user interface, and superior UI controls.

- **Higher Performance:** 
A responsive result and high performance are achieved by.NET due to its high speed, and just-in-time compilation. The response time is also low. Businesses are satisfied with flexible processes and a better dynamic user experience.

- **Cloud-based Web App Development Support: **
We can develop the cloud-based application using .NET. With the simple publishing procedure, developers can deploy the application on the Azure cloud with this setup being simply possible in the visual studio IDE. Numerous Azure features are available in Visual Studio Developer Tools, which we can incorporate into the application.

- The .NET Framework is best when you:
- Choosing .NET framework for a time-sensitive project
- If you prefer a stable environment then .NET framework should be your pick
- Have nearer release schedule
- Existing expertise with this technology
- Have a.NET Framework application that needs its functionality to be expanded (vs. migrating it)
- Using Windows Forms or WPF for creating Windows client applications?
