Be careful with POS payments during V34 upgrade

If you have a legacy POS payment connector integration with IPaymentDevice implementation, you must update it before upgrading to MPOS V34 or moving to StoreCommerce App.

In V34, Microsoft added a new parameter RequestContext in the hardware station extension. This parameter doesn't exist in the IPaymentDevice interface, which is why you must remove

IPaymentDevice from hardware station extension declaration.

New method parameter

Make sure that Legacy.PaymentDeviceAdapter is commented out in DLLHost.exe file

Add a parameter RequestContext in the following methods

AuthorizePaymentAsync

CapturePaymentAsync

VoidPaymentAsync

RefundPaymentAsync

FetchTokenAsync

And make sure that you pass this parameter value into GetPaymentProcessor method.
