How to get types from a shared project

Question

I have two projects, one of them Web API and other is a shared project. To register my services I use:

var serviceType = typeof(IService);
        var allTypes = Assembly.GetExecutingAssembly()
            .GetTypes()
            .Where(x => serviceType.IsAssignableFrom(x))
            .ToList();

However, services from shared project aren't getting registered.

How to get types from shared project?

typeof(IService); means you are getting the type of an interface not class.Are you sure the service type you need an interface or class? — Hameed Syed, Aug 02 '17 at 06:21

The types defined in your shared project can be found in the compiled assembly for your WebApi project.

When building a project that references a shared project, the sources from the shared project are compiled as if they were part of the projet referencing it, not in a separate assembly.

So if you have a class ServiceImpl implementing IService in your shared project, the compiled WebApi assembly will expose it.

If you cannot find the type in the compiled assembly then the problem is elsewhere. Maybe the reference is missing? Maybe the build is failing and the code that is executed isn't up to date?

Not sure is my solution elegant enough or not, but I put a Helper class into shared project with

var serviceType = typeof(IService);
    var allTypes = Assembly.GetExecutingAssembly()
        .GetTypes()
        .Where(x => serviceType.IsAssignableFrom(x))
        .ToList();

and it gave me what I wanted.
