I've always like C# for its multi-paradigm nature, good runtime, and excellent collections framework. It's basically what Java could/should have been.
Unfortunately the legacy tooling is infuriating to work with. It's been steadily improving for the past few years with the advent of .NET Core but in practice this doesn't mean much. If you work at a ".NET shop" then odds are that the devs that work there have been firing up Visual Studio and creating solution files for the better part of two decades; good luck getting them to use dotnet or Docker Compose, not to mention the long-lived legacy apps floating around that are still built that way and live on IIS in a corporate datacenter someplace.
Yes, C#'s greatest weakness is the tooling. There's no autoformatter, for heavens sake. (There are two in theory, but one is prettier's support for an old version of C# and one just doesn't work). And, yes, solution files and project=assembly are both absurd.
There's autoformatting tools in C# editors (VS, VSCode) and also the dotnet-format command-line tool for non-editing environments. Have you tried these?
The modern .NET tech stack has radically changed so much in the past 4 years that it's not surprising that so many folks are still having flashbacks to the old proprietary days.
