Studio 2017 - SR1: System.MissingMethodException

Good day,

 

I have developed a plugin that was working on both 2015 and 2017 versions. After updating Studio 2017 to the latest version (14.1.10009.15268) i am getting the following error: Method not found: 'Boolean Sdl.TranslationStudioAutomation.IntegrationApi.Document.SetActiveSegmentPair(System.String, System.String). 

I noticed that one out of the three method overloads is obsolete. I am not using that one though (not that it would be discontinued). The plugin was working fine in earlier versions of the SDK. I cannot find any other clue regarding what is wrong regarding the Sdl.TranslationStudioAutomation.IntegrationApi.dll assembly. 

I also point the fact that this is/was a public/exposed method and no kind of reflection was used for this matter.

I would appreciate any suggestions.

 

Best regards,

George
