Do you not use it any more? Have you switched to Eglot or something?
I use lsp-mode, was going to switch to eglot, but it doesn't have the features that lsp-mode has, like lsp-ui (as far as I can remember), and the last time a compared (last year), the performance impact was somewhat noticeable.
I work on a huge codebase with eglot+clangd and the few times where it gets slow is where there are tons of flymake warnings. Like when you enable all the clang-tidy checks.
I officially started with .NET back in 2008 and, at the time, you really had to use Visual Studio. I knew emacs was not an option at that time. Since .NET Core I knew I was getting closer and closer for emacs becomming an option.
Then comes Visual Studio Code.
I have experiemented with C# development in emacs for a few years, now. I cannot remember now but it was likely with lsp-mode. When I found out eglot is in v29, it was time to revisit it. It has been positive so far.
I actually forced myself doing .net development in emacs this weekend. I am 90% there! Need to see if I can debug in emacs, now. I hope so!
Once I am happy, I will continue to add more interactive functions, saving me typing 'dotnet cli..' commands. I also need to revisit yasnippet to make coding more effecient in C#.
Getting started with eglot and C# was pretty painless, thanks to this link:- https://www.johansivertsen.com/post/emacs-29-csharp/
This was also the Visual SourceSafe days. How I do not miss that!
C# wiggled its way in eventually.
Back in 2008, I was pretty much using Emacs for most programming languages. The only exception was C# and Javascript.
As the years pass to now, I rarely use a programming language outside of emacs. I have enough years in my career to not tell me what I can and cannot do to get things done.
That was also the project where I tested if git reached the point where you can have "normal" people work with it as well (which worked pretty well). I never accepted any project where they'd have me work with idiotic proprietary source control, unless the project was "migrate away from that".
Since around 2014 -- It has been Git all the way.
Well, until recently. Codebase at my current job is all contained in a single Subversion repo. It is difficult to maintain and branching takes GBs!
One of my first goals is to move over to Git, and into smaller Git repos. Of course, I have Magit to get it done. :-)
I like how people think I am purposely being different or difficult because I do C# development in emacs. Many have never heard of it. If they have its from forums or youtube videos.
Think of their mindset -- Its not like I have moved away from Visual Studio to Visual Studio Code. I am using Emacs. They must think I am trying to be difficult or special.
I have also swapped my L-CTRL key with CAPS specially for improving my emacs experience.
Regardless, when we do pair programming (or something) on my screen and they watch me use Emacs on a C# project, they soon understand. :-)
