Have created a CRM 2013 Plugin to update a simple field in Opportunity, running this in my DEV ENV. Form has field is visible and editable.

My plugin keeps on having an OpportunityUpdate.Plugin: System.MissingMethodException: Constructor on type 'OpportunityUpdate.Plugin' not found message.

Below the Main Plugin and the UpdateOpportunity, also for some reason the update to the "pearl_opportunityguid" doesn't happen and doesn't error either. Any help would be greatly appreciated.
