c# - Side by side assemblies in .NET Core

Question

I am developing app where project has nuget dependency on PROJECTB of version 1.0. However in development scenario I want to use this PROJECTB as submodule. In add that project to solution and change version to 2.0

However only PROJECTB of version 1.0 is in bin folder. I tried manually adding PROJECTB of version 2.0 to my project references of my main project but I get error:

An assembly with the same simple name PROJECT2 has already been imported
