Adding Additional Activity .cs and Layout axml Using Visual Studio 2015.

I\'m very new to Xamarin and Android

Answer 1

(VS 2019) I did the previous solutions and nothing, I had the same problem and the solution for me was to remove '&' from the text of TextView, I was trying to Set the text to "text&text" even &&(I though it was like mnemonics as in WindowsForms) didn't work so I had to remove it and it fixed.
