Flurl throws an exception (MoveNext())

I am attempting to call a Web API POST action (.Net Core) from a WinForms app (.Net Framework 4.7) via Flurl. However, when I try to debug the exception Flurl throws, my request doesn't even enter the controller itself.

Trying to debug the problem line by line didn't help. I suppose because since Web API and WinForms are two different projects in the same solution, I can't enter the debugging from the form to controller?

Basically I instantiate an object of a class I made and call my API service:

var entity = new UserRegistrationModel
{
        Username = "test",
        Email = "[email protected]",
        Password = "test",
        PasswordConfirmation = "test",
        Roles = new List<int>()
};
entity.Roles.Add(1);
entity.Roles.Add(2);

await _service.Insert<User>(entity);

This is what my call looks like:

public async Task<T> Insert<T>(object request)
{
        string url = "https://localhost:44365/api/users";
        return await url.PostJsonAsync(request).ReceiveJson<T>();
}

My controller should handle it by adding a new user to the database and returning an User object, but the method's code gets never executed.

[HttpPost]
public User Post(UserRegistrationModel request)
{
        return _service.Register(request);
}

It could be that Flurl is unable to send a POST request to your localhost due to HTTPS. Try disabling SSL in your ASP NET Core Web API project.
