  1. Hello. Thanks for another year of the F# advent calendar. As in previous years, could I please have December 31st?


    1. Hi Sergey!

      Could I have a go at the 16th of December? Hopefully I can come up with something by then.

  2. Hi Sergey,

    I’d love to participate on this F# advent but I have a question about it.

    I already have a subject I wanted to share on my blog, but it is a serie (maybe 4-5 blog posts) and it is 50% F# and 50% explaining the domain. Do you think it can fit in the F# advent ?

    (And thanks a lot for your work, I read your F# Weekly since several years now, I really enjoy it 🙂 )

    1. Hi, yes I can fit. Let’s book the date for one post from that series (it should have some F#) and on this page I will link the whole series as your contribution.

      1. Hi,

        I’ll take the 14th of december if possible.

  3. Hello Sergey,

    New F# developer here (you can thank Kai Ito for my participation) and I’d like to reserve the slot on Dec 11th.

    The topic would be ‘From C# to F# in 30 days’.

    Thanks for the effort in keeping this up.

    Happy Holidays!

    1. It is already divorced because you can leave a comment here to join and post link to your post as well.

      Update: also added Mastodon as an option, why not.
