The 10 foot line :)

This question is not specific enough to answer. Are you referring to .net or perhaps to support for networking? You must be much more specific.

Java can run on any operation system(platform independent) but .net runs only under windows.

No, .NET only runs on Microsoft platforms (Windows, XBOX, etc.)

.NET can be run on Linux&Mac with Mono. However, Mono does not provide Windows-specific libraries.

The .NET Framework and .NET are related but different technologies:

• .NET Framework - This is Microsoft's original implementation of .NET for building applications that run on Windows. The .NET Framework provides a runtime environment and libraries for .NET applications. It was first released in 2002.

• .NET - This is the current evolution of the original .NET Framework. Whereas .NET Framework was Windows-only, .NET is a cross-platform, open-source implementation that runs on Windows, Linux, macOS, etc. It supports more modern application scenarios like cloud, mobile, and web apps.

Some key differences:

• .NET Framework only runs on Windows. .NET runs cross-platform.
• .NET Framework is closed source. .NET is open source.
• .NET Framework is only supported by Microsoft. .NET is supported by Microsoft and the .NET community.
• .NET Framework is legacy technology. .NET represents the current direction.
• .NET has unified frameworks like .NET Core and .NET 5+. .NET Framework had separate versions like .NET Framework 3.5, 4.0, etc.

In summary:

• .NET Framework is the original Windows-only .NET released in 2002.

• .NET is the new open-source, cross-platform version of .NET, representing the future direction.
