Is it possible to build multiple ASP.NET MVC projects as one?

Question

ASP.NET

Good day.
My project structure is something like this:
- Project
-- Project.Auth
---- Project.Auth
---- Project.Auth.Data
---- Project.Auth.Impl
-- Project.Common
---- Project.Common .BlaBlaBla
---- Project.Common.BlaBlaTwo
-- Project.Web
---- Project.Web.Auth
---- Project.Web.Admin
---- Project.Web.Common
---- Project.Web .portal
etc.
Solution Project.Web contains ASP.NET MVC applications, each of which will be hosted on its own subdomain (eg auth.project.com). Portal will be root, i.e. without a subdomain. Common - contains resources common to all projects (styles, scripts, etc.).
Question: is it possible to make the whole project go into one folder? Or, if the first option is not possible, to assemble the project in such a way that the common resources (dlls, scripts, styles) are in one place?

Answer 1

There can be either a relative path, moreover, in the opposite direction "../../..",
or an absolute one.
