I programmed professionally in .NET around 2003 with the initial versions. I liked it a lot and over the next years I tried to keep up to date about it on my spare time (I remember reading about LINQ development, the amazing CLR improvements, etc), all while I developed in Java, ruby and nowadays TypeScript. The problem I see with .NET now (I did some tinkering on it via Unity) is that even though some of it is "open source", Micorsoft's grip is still pretty tight on it. Or at least it feels like that. Given Microsoft's history I find it very difficult to "commit" to using the .NET framework for something real, because I feel I will be bitten back with the 'proprietary' aspects of it as soon as I go to production. It's a sunk cost that I cannot afford. And it is not personal 'hatred' or anything given that I use VSCode as an editor and TypeScript itself comes from Microsoft. I wish Microsoft would donate .NET to some 3rd party open source foundation (like what happens with all Apache projects, or LibreOffice, the MariaDB foundation, etc).
