Thanks for any help

Answer 1

You are saying that you have a private void-returning method named ChangeStakingType that takes one parameter. The parameter's name is "newType" and the type of the parameter is AGeeksToyToolStripMenuItem<EnhancedType<StakingTypeEnum>>.menuData. But there is no type named menuData in your program. There is a field called menuData and a type called MenuData<T> but there is no type called menuData.

Answer 2

C# is case sensitive.

You are trying to use the menuData class, when the actual class is called MenuData. Make that M uppercase
