Attribute	.NET Core	.NET Framework
Open-source	Yes	No
Platform support	Cross-platform	Windows only
Deployment	Self-contained or framework-dependent	Framework-dependent
Performance	Improved performance	Less performance optimization
Compatibility	Not backward compatible with .NET Framework	Backward compatible with older versions

Introduction

When it comes to developing applications on the Microsoft platform, developers have two main options to choose from: .NET Core and .NET Framework. Both frameworks have their own set of strengths and weaknesses, making it important for developers to understand the differences between the two in order to make an informed decision on which one to use for their projects.

Performance

One of the key differences between .NET Core and .NET Framework is their performance. .NET Core is known for its improved performance over .NET Framework, especially when it comes to running applications on non-Windows platforms. This is due to the fact that .NET Core is a cross-platform framework, allowing developers to build and run applications on Windows, macOS, and Linux. On the other hand, .NET Framework is limited to running on Windows only, which can impact performance when running applications on other platforms.

Compatibility

Another important factor to consider when choosing between .NET Core and .NET Framework is compatibility. .NET Framework has been around for a longer time and has a larger ecosystem of libraries and third-party components that are compatible with it. This can make it easier for developers to find and use existing code when building applications. On the other hand, .NET Core is a newer framework and may not have as many libraries and components available, which can make it more challenging for developers to find the resources they need.

Deployment

When it comes to deployment, .NET Core has a clear advantage over .NET Framework. .NET Core applications can be deployed as self-contained executables, meaning that all of the necessary dependencies are included in the deployment package. This makes it easier to deploy and run applications on different machines without having to worry about installing additional components. On the other hand, .NET Framework applications require the framework to be installed on the target machine, which can make deployment more complex and time-consuming.

Open Source

One of the biggest differences between .NET Core and .NET Framework is their open-source nature. .NET Core is an open-source framework, meaning that developers have access to the source code and can contribute to its development. This has led to a more active community around .NET Core, with regular updates and improvements being made by developers from around the world. On the other hand, .NET Framework is a closed-source framework, which means that developers do not have access to the source code and cannot contribute to its development.

Tooling

When it comes to tooling, both .NET Core and .NET Framework have their own set of tools that are designed to help developers build and debug applications. However, .NET Core has a more modern and streamlined set of tools, including the .NET Core CLI and Visual Studio Code, which are optimized for cross-platform development. On the other hand, .NET Framework relies on Visual Studio as its primary development tool, which is more focused on Windows development and may not be as well-suited for cross-platform development.

Conclusion

In conclusion, both .NET Core and .NET Framework have their own strengths and weaknesses, making it important for developers to carefully consider their requirements before choosing one over the other. .NET Core is a more modern and cross-platform framework with improved performance and deployment options, while .NET Framework has a larger ecosystem of libraries and components that may be beneficial for developers working on Windows-specific projects. Ultimately, the choice between .NET Core and .NET Framework will depend on the specific needs of the project and the preferences of the development team.
