Forum Post: Sage 50 2016 SDK - The type or namespace name 'Sage' could not be found (are you missing a using directive or an assembly reference?)

Hi, I tried to connect to Sage 50 2016 but It is impossible, when I compile my code, I get this error: Error 4 The type or namespace name 'Sage' could not be found (are you missing a using directive or an assembly reference?) It is a little weird, I added the references from Sage 50 API folder and they are not recognized. I am using .NET Framework 4.0 and the following references were added to the project: Sage.Peachtree.API (Runtime: v4.0.30319 Version 2016.0.0.90) Sage.Peachtree.API.Resolver (Runtime: v4.0.30319 Version 2016.0.0.90) Any ideas what I missing..??? Thanks
