SharePoint 2013 with .net 4.6 Workflow Issues RRS feed

  • Question

  • Hi

    We had an issue several months ago where we installed VS 2015 on our SP dev server - this installed .net 4.6 and updated a Microsoft.Activities DLL in the GAC which caused workflows to stop working.  

    This was fixed by uninstalling the .net 4.6 framework and downgrading the Microsoft.Activities in the GAC by copying it over from a working machine.  

    The error in the event log was  - 

    "

    Dispatcher failfast is causing the Workflow Manager backend to terminate. Exception: System.AggregateException: The dispatcher failure rate has reached 11%. InnerException is the last failure; see traces for other failures. ---> System.TypeLoadException: Method 'SubscribeCurrent' in type 'Microsoft.Activities.Hosting.HostedNotificationExtension' from assembly 'Microsoft.Activities.Hosting, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' does not have an implementation.

    After installing VS 2015 update 1, we have come across the same issue again.  We are wondering if we should fix it the same way or if there is a better way since this will probably keep happening.

    Thanks

  • Hi Victoria

    The solution suggested is what we tried before - we were wondering if there was a better way, but it seems there are no answers so we fixed the same way as before.  For now it is working, but sure we will encounter the same issue when we update VS again.

    Thanks
