Mismatch between processor architecture.

Steps to reproduce

1. In VS 2015 create a .net web project targeting full framework.
2. Add a Nuget package reference to “Microsoft.ServiceFabric.Services” which targets only AMD64. or any other package that targets only AMD64.
3. Build -> build will be fine.
4. Open this project in another machine with VS 2017 and this will migrate the project.
5. Build

Expected behavior

Build should succeed

Actual behavior

Build shows several warnings

I’m able to reproduce this issue as well. I have tried with both x64 and Any CPU configurations in my solution.
