As a contractor, I frequently browse job postings on platforms like Indeed and LinkedIn. Over time, I’ve noticed a trend—Microsoft .NET seems to be less prevalent in job listings today than it once was. This observation has led me to want to shine a spotlight on the companies that still leverage .NET in their tech stack, as well as those that don’t.

By supporting these companies—whether through their products, services, or even advocating for them in your professional networks—we can help reinforce the value of .NET in the industry and encourage its continued use. Here is a list of companies that actively use .NET in their operations. If you know of any other notable companies that should be added to this list, or have insights on how any of these companies utilize .NET, feel free to share in the comments.

Let’s show our support for these organizations that choose to build with .NET!
