Not able to connect to RobotStudio with VS 2017

[mjkoehle]

When trying to connect with RobotStudio using arm.Connect(); fails with:

System.IO.FileNotFoundException
HResult=0x80070002
Message=Could not load file or assembly 'ABB.Robotics.Controllers.PC, Version=6.5.7392.129, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.
Source=Machina
StackTrace:

at Machina.Control.ConnectToDevice(Int32 robotId)
at testMachinaApp.Program.Main(String[] args) in C:...\testMachinaApp\Program.cs:line 20

This is with VS 2017, using framework .NET Core 2.1. With VS 2015 and .NET framework 4.6.1, there is no issue.

Hi @mjkoehle! Sorry to hear.

1. Are you using Machina v0.6.2 or another release version? Or are you building from source?
2. Have you checked if ABB.Robotics.Controllers.PC.dll is being copied to the folder from which Machina.dll is being loaded in your program?

Thanks for reporting @mjkoehle.

Seems like there is a compatibility issue, will look into it.

However, we are trying to move away from external dependencies in the future. Maybe the way to go in the future is to simply not rely on any other library...

Hi Nono, I've spoken with Jose Luis about this. I believe I tried 6.1 and 6.3 of the distributions. I made sure ABB.Robotics.Controllers.PC.dll was in the same folder as Machina.dll. I also tried referencing ABB.Robotics.Controllers.PC.dll directly. I'm running on VS 2015 now, but if you'd like me to check something, I can go back to 2017. m MichaelKoehleArt.com

I think the issue is clear here (of course I am guessing 😉 )- ABB's dlls are not supported in .net core - have you used the .net core checker to see if the assemblies are supposed to work?
