I've just published new version of @IonideProject (4.9.0) that includes support for new semantic highlighting feature released yesterday in @code.

It means your code should be more colorful, and syntax highlighting should be more accurate. #fsharp #toolingAdventures pic.twitter.com/bDtT5GJ9JJ

F# world – I remember someone wrote F# computation expression builders "list { .. }" and "array { .. }" for generating lists/arrays via a mutable ResizeArray (rather than an underlying sequence expression for "[ .. ]"), and got good perf gains.

Anyone remember that? Link?

Hi F# users, I recently started to use dependabot for watching my dependencies. It works really great for js packages. But currently it only watches nuget references in fsproj files. Someone interested in adding a Paket lock file crawler?https://t.co/ISYYIkNu1a #paket #fsharp
