C# netcore app could not resolve Rebus.Bus.IBus in Docker Windows Container

Question

I have a simple netcore 3.0 console app initializing a connection with Azure Service Bus using Rebus(v7.1.0). I built the app to be selfcontained, then I run it on my laptop and on another computer we have at the office.

The problem :

The app is throwing an error (see below) only on the second computer running in a docker container.

What I've try :

• Running the app without docker on both machine. OK
• Running the app in a docker container on my laptop using the same Dockerfile. OK
• I don't find anything relevant in docker logs.
• Re-install docker on the the 2nd computer.
• Try an older version of docker. Same problem occur

Questions :

• Do you know why this is happening ?
• I am relatively new to docker, can you guys provide me some tools or tips on how to understand what is happening ?

Specs :

My laptop :

• Windows: 1903 (Build 18362.657)
• Docker desktop community: 2.2.0.3 (42716)

2nd computer :

• Windows: 1809 (Build 17763.194)
• Docker desktop community: 2.2.0.3 (42716)

Thanks a lot for your help !
