Method Not Found when running the application after some Windows updates
Hi everybody, After some Windows updates, I encountered a really annoying error. I don't have any compile errors, but when I run the application I get 'Method Not Found' error. Method not found: 'System.Collections.Generic.IList`1<Microsoft.SharePoint.Client.ListItemFormUpdateValue> Microsoft.SharePoint.Client.ListItem.ValidateUpdateListItem(System.Collections.Generic.IList`1<Microsoft.SharePoint.Client.ListItemFormUpdateValue>, Boolean, System.String)' I checked the ListItem class and the method is there. We are using the Microsoft.SharePoint.Client, Version=15.0.0.0. Do you have any idea what could be the problem? Thanks, Cristina.
