.NET 3.0 framework problem

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

This topic area includes legacy versions of Windows prior to Windows 2000: Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions including Windows Mobile.

Windows OS

Windows 11 is a major version of the Windows NT operating system developed by Microsoft that was announced on June 24, 2021, and is the successor to Windows 10, which was released in 2015. 

Windows 11 was released to the public on October 5, 2021, as a free upgrade via Windows Update and Windows 11 Installation Assistant on eligible devices running Windows 10.

Windows 11 features major changes to the Windows shell influenced by the canceled Windows 10X, including a redesigned Start menu, the replacement of its "live tiles" with a separate "Widgets" panel on the taskbar, the ability to create tiled sets of windows that can be minimized and restored from the taskbar as a group, Microsoft Teams being integrated into the taskbar, and new gaming technologies inherited from Xbox Series X and Series S such as Auto HDR and DirectStorage on compatible hardware. Internet Explorer (IE) has been replaced by the Blink engine-based Microsoft Edge, while IE's core is retained for Edge's IE mode, and Microsoft Teams is integrated into the Windows shell. Microsoft also announced plans to allow more flexibility in software that can be distributed via Microsoft Store.
