Has enabled building responsive multi-threaded applications while supporting rapid deployment workflows
Microsoft .NET Framework has already made significant improvements by becoming open source. Many developers are contributing to Microsoft .NET Framework, not just Microsoft itself. They have ported it to many platforms and allow a healthy ecosystem of open source tools. They have moved from Visual SourceSafe to supporting Git with Microsoft Visual Studio. Their IDE, Visual Studio Code, is open source and multi-platform. There are many third-party tools available, including AI-based tools such as Cursor and Bolt, which are forks of Visual Studio Code. Based on my understanding, I don't have any suggestions for improvement as they are already doing an excellent job.

Improved on-premise performance has supported faster, secure apps and clearer server monitoring
One thing I appreciate most about Windows Server AppFabric is because it's widely used; it's easier to get solutions online from other communities when I am stuck. Because it is widely used, it's easier to get solutions and also easier to work with. Especially after I found 2019, I have worked with 2019 and I appreciate it. It's easier to get solutions. After implementing Windows Server AppFabric, I can say I love the speed. The functionality and speed are good. Earlier, when they added more people, I could see some lagging. But now, I have no issue even if I double the users, even if I add 30% of users or any applications, it will still be fast. It increased the speed and also security. I've noticed the new one I have is good and secure. I love the security. The monitoring capabilities of Windows Server AppFabric help me improve service visibility and troubleshooting. In a day, I have to go through a lot of the logs and also the utilization. There, I see the CPU. I have to do the utilization, and I can see what is utilizing the most. By doing this, I can be able to tell what, in case I need to do an upgrade, what I might need to provide the upgrade or maybe increase in users that will not affect the operations.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Firstly, I appreciate the decision to use Microsoft .NET Framework. I find it to be an excellent language, with a history rooted in providing an alternative to Java, albeit with initial challenges. It is gaining popularity and may be voted the most desirable programming language. What I particularly like about .NET is its language efficiency. While C# is the primary language, the platform also supports others, catering to those inclined towards functional programming. Although I started with Shell, I'm still grasping the concept of functional programming. Despite initial reservations about object-oriented programming, I acknowledge its advantages. .NET is a safer option, and despite criticisms, it has evolved over the years. One notable aspect is .NET's transition to an open platform in recent years, distancing itself from being exclusive to Microsoft engineers. I appreciate the versatility of .NET, enabling code production for a wide range of platforms, presenting a strong competition to Java. It allows targeting practically any physical platform, showcasing its flexibility. These qualities contribute to my positive view of .NET, totaling thirteen aspects that I find appealing."
