AltCover (code coverage for #Dotnet built in #fsharp) status update

This year I've had less time free to get into code-mode, and what I've had has been mostly taken up with keeping ahead of library updates and the net10.0 previews. State of play of the net10.0 support release here -

x.com/stevegilham1/status/1978

too long a post to fit here.

New blog post, about one of the more obscure things that have been holding up a new AltCover release, while I've been trying to clear years of accumulated "accidental", or no longer relevant, code from the codebase

After a couple of weeks of distractions I finally got around to getting my #OpenSilver in #fsharp test applet running, working around quirks from changes that should in time make things simpler with proper language support - I've blogged the update here

New release of my Gendarme fork for static analysis of #dotnet

The latest (7.0.400) & all 8.0pv #fsharp compilers drop some scruffy code (incl. an unsealed internal Attribute type w/o a usage attribute) into most assemblies, this release recognises & ignores these injections.
