How can I use an interface in a main controller of an ASP.NET MVC project?

Question

I am working on ASP.NET MVC project where I have one solution dotnetmvc which contains two projects:

dotnetmvc (main project)
Service (contains an interface for it).

My problem is that when I am trying to use an interface from the Service project within a controller of the main project then I am not getting a reference to the interface.

Please refer to the below screenshots:

What am I missing?

Please show your IUser code with namespace.

I know of 2 reasons why this would happen:

your interface is not public. make sure you add public.

public interface IUser
{
 .......
}

the project dotnetmvc is on a lower dotnet version as the Service project

Right click on each project, select properties and make sure dotnet version is the same on both projects
