EF Core Migration: Could not load assembly 'AssemblyName'

问题

The command "Add-Migration InitialCreate" generates the following error message:

Could not load assembly 'MathModelApp'. Ensure it is referenced by the startup project 'MathModelApp'.

What does the error message mean?

I am using netcore 2.1, Target Platform is x86.
