Context
I am building my package using Visual Studio (2022). My solution has two projects, the project to be packaged (MyComponent) is referencing to an other project (Core).
All package configuration metadata is in my MyComponent.csproj file, so the .nuspec file is automatically generated during the build in the /obj folder as MyComponent.1.0.0.nuspec
Issue
The generated package contains only one assembly: MyComponent.dll. I would like to include the Core.dll assembly.
Question
How and where to configure the build process to include the Core.dll assembly? (or would it be better to have Core as a package too, and configure package dependency? Also how, if I have no direct control on the .nuspec file content?
(In case this question can be answered in more generic form, then the would be extra useful. I mean, having .nuspec automatically generated, all XML schema we knew how to set there, not how can be set in .csproj file?)
