Additional Notes

I was unable to find a wordmark svg for 2022 Visual Studio. It seems like only visual studio
The dark purple color #52218a was used for the font SVGs.

Thank you for this contribution! 🚀

Great work again!
I couldn't find any official wordmark versions either, but I swear I've seen it somewhere. Perhaps we could vectorize this version?

@canaleal I'll let you decide if you want to try making wordmark versions, or if you just want to merge it. Either is fine by me :)

[canaleal]

I'm gonna try to vectorize the wordmark image. Also yeah, I distinctly remember seeing a wordmark svg some time ago.

Here goes a suggestion based on the original version.

I'm still have problems with Filezilla gradient (text) as I'm having here in this icon. 💡 I know how to solve it now.
Another thing is that the colors and the proportion of the lemniscata styled icon is a little bit different from original version.

Updated version - with gradient

@canaleal whenever you have time, please add the wordmark versions :)
See lunatic-fox's suggestion in the comment above

I added the wordmark suggestion made by @lunatic-fox, and made plain + line versions of it.
Everything looks good now! ✅
