C# translation is a mess and needs to be cleaned up:

• unused functions,
• HTML markup leaking from messages,
• Solution funciton is an instance method without a good reason,
• Assertion messages are missing,
• No tests (and no spec) on mutation of inputs

I'm looking at this, and honestly... I have no clue what's being done on the second line before the :

For l > 9, you code returns some value. It should always return 0.

i removed this test case from C# as it went against the specifications.

"and your partner" is a really easy change.

It's easy to be inclusive. If the kata is written using "You" then don't bring gender/race/religion into it.

Coders can figure out how to use variables, they can figure out how to make problem descriptions more inclusive.

The original text is virtue signaling. I'm asking for equality.

If your culture or values are intolerant, that's your problem.
Asking for equality for literally half the people in the world shouldn't be offensive anyones values. I don't think we should welcome a culture of misogyny here.

d is the poorly named static string array.

I'm not sure how this became a solution given it has a syntax error in d.Contains... and changing the d to s the solution doesn't pass the tests.

The description now does. The title can only be changed in the kata editor, and most people are allergic to that.

Brilliant solution to solve the rock-paper-scissors winner mathematically by their unicode char values.

The texts are not changed. The discussion is over for me at this point. If you want, you are welcome to use these vault katas as a base for your own katas. Have a nice day. (@dfhwze: Thank you very much for your comment.)

Kees, now you are the one using stereotypes, which is exactly the thing you are blaming the other of doing ;-) Anyway, there are different cultures, each with their own values. Who are we to push our values onto others ... This is exactly why I find the original comment by dlcoe misplaced. It's virtue signaling and does not add anything useful to a programming challenge.

Three years later, this topic is so hot that even I noticed the bias here. I can't say for sure, but looking at the description this might be uploaded by an Eastern European alpha male. They have indeed a bit old fashioned ideas about gender (identity), relationships (male/ female, that's it), sexual preference and pronouns, preferred or not.
Give it another few centuries and they'll turn around. ;-)
