The title is unfortunate marketing. Fake is great for building a lot of stuff, not just .NET things.

Wasn't intended in ANY way to be marketing. I didn't realize folks were using it to build other stuff. Gimme some links and I'll update the post.

Actually I created it to build Microsoft Dynamics NAV applications, which were not .NET at that time.

Not sure why the negative attitude..? A great thing about FAKE is that it can be used without worrying much about the context. Yes, it is written in F# and F# is mainly functional, but FAKE is just a great tool for anyone - and as Scott correctly points out, you don't even need to understand much F# to use it.

I stand by what I wrote and it has nothing to do with any negative attitude, I meant no disrespect. Perhaps it's enough for you that people "don't even need to understand F#" to use F# tools (of which there are many excellent ones, FAKE being one), but I would much prefer that they did. This "context" would make any .NET developer more informed and I see no reason why we should hide F# from anyone. Perhaps I am too carried away, but I certainly want Scott to learn about and embrace FP so that he can pass that onto others, which, I hope you agree, he does pretty well.

Looks like this could replace PowerShell for deployment scripts. Something I personally would find very interesting. Could this work with Octopus Deploy?

Yes, I mention Octopus. There are some plugins I think.

There is a small tutorial: http://fsharp.github.io/FAKE/octopusdeploy.html

I do use F# as scripting language on Windows. It is a possible way to sneak it in.

Can I use it as a substitute of psexec.exe executing my scripts on remote machine?

LOL, I totally love that name!
