Hi List
I hope someone can point me in the right direction :)
I am battling with this Error that shows up when I open the project, if I ignore the communication to the PLC is OK, but the communication I have to the database fails without any warnings.
Method 'System.Collections.ObjectModel.ObservableCollection`1[[MfgControl.AdvancedHMI.Drivers.PLCAddressItem, MfgControl.AdvancedHMI.Drivers, Version=3.99.19.2, Culture=neutral, PublicKeyToken=null]].Add' not found.
I am running windows 10, I get the same error if I open in VS 2017 or 2019
Is this a Microsoft thing ?

I found that it is related to DataSubscriber2, all collections in my data subscribers (5 in total) where blank.
I think this started when i accidentally added a DataSubscriber2 to a different page and not the mainpage, I have corrected the mistake, but I have a hard time getting back on track, I have tried deleting the old DataSubscribers and added new ones, but I can't add a new member to the collection.

Visual Studio is out of sync with the collection type. Close all Documents, exit VS, then Re-open
If that does not fix it, then perform a full clean

I found a copy of a version before the big crash and added the few changes I made, so i am back up and running
But just to practice I will try and go true the full recovery, som I am prepared for the big crash one day.
Thanks again
