JetBrains Rider and get over your hangups so you can be productive. Now, you'll have to pay these professional developers for their work making an excellent cross platform IDE for you but you can leverage their work (and Microsoft's great language and platform tools) for your own benefit so it's a win/win.

Beyond that, no offense but I don't think C# devs don't owe you anything, it's on you if you have criteria that excludes you from using all these awesome things.

If your religious beliefs are a sticking point, then so be it.
