Hi there,

Can you provide a little more information? e.g. what have you tried, where are you seeing this error, what is your intended outcome etc

Compiler Error CS0029 generally refers to when you're trying to convert type 'type' to 'type'. More info can be found on Microsofts website here, I don't have much experience with this error so hopefully someone can explain in more detail.

It should be obvious that a function of type EventHandler cannot return a button. The error message makes that perfectly clear. What do you want with that function GetClick() anyway ? It's not even being used. And you already have a function that returns button1.
