Hello everyone,
looking for help regarding to integration of Zenon AddIn. We are creating a Addin that shall do several stuff like running WebSocket server, Http Api server and of course consume some data from Zenon itself, like Variables or Language texts.
I am using Autofac for DI and have troubles to get it working. First anyone around who successfully used IoC inside AddIn implemenation?
Second topic is related to error: Could not load file or assembly 'System.Web.Http, Version=5.2.7.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
- I have added library at AddinInfo.cs file, like [assembly: AddinModule("System.Web.Http.dll")] It mitigates the error, but then next error related to missing Autofac assembly appears and second declaration like [assembly: AddinModule("Autofac.dll")] causes the error (duplicit addinmodule).
When I create all classes manually with new, it usually works.
Any hint is most welcome. Cheers, Jaroslav
