AuthorizeNet - Address and Customer

Hello, please your support I am trying to install the AuthorizeNET plugin, but send the following errors:

Error  CS1061  'Address' does not contain a definition for 'StateProvince' and no accessible extension method 'StateProvince' accepting a first argument of type 'Address' could be found (are you missing a using directive or an assembly reference?)  Nop.Plugin.Payments.AuthorizeNet  C:\Trabajo\OTROS\ecommerce\nopCommerce-develop\src\Plugins\Nop.Plugin.Payments.AuthorizeNet\AuthorizeNetPaymentProcessor.cs  164  Active

Error  CS1061  'Customer' does not contain a definition for 'ShippingAddress' and no accessible extension method 'ShippingAddress' accepting a first argument of type 'Customer' could be found (are you missing a using directive or an assembly reference?)  Nop.Plugin.Payments.AuthorizeNet  C:\Trabajo\OTROS\ecommerce\nopCommerce-develop\src\Plugins\Nop.Plugin.Payments.AuthorizeNet\AuthorizeNetPaymentProcessor.cs  292  Active
