bug#48871: 27.2; Unusably slow in C# mode |

Hi,
I don't recall installing c# but may well have happened.
>From package-list-packages:
csharp-mode 20210328.2004 installed C# mode derived mode
Which does not say built-in so likely I did. Looking in the unzipped
emacs 27.2 , no relevant *sharp* file in it, and did find it in the
elpa directory, so I guess must have.
Started with -Q. Did the M-x load-file for csharp-mode.el (FYI also
had to do load-file for csharp-compilation.el before that to make it
happy).
Finally got to load the C# file itself, exactly the same. No faster.
Troublesome C# file attached.
cheers
jan
