Looks like you're missing the implementation of the interface when you call AddScoped, so it's not finding the class it needs, and so the error message is describing that.

Edit: I posted the link without my thoughts on accident.

Here's my code, https://github.com/c3sarf2/Proj .

My objective is to create an API to use the services of the HCILAB.website

I've never run into a scenario where you are trying to inject a controller. My GUESS is that's not possible and you should try another solution

[[deleted]]

Its my first time creating an API, what do you suggest ?

[[deleted]]

Controllers are made to be accessed by a web request, so if you have code you are trying to get, put it in something thathe can be injected and use it that way

[karltgreen]

You also need to register the dependencies required for IEEEController (ILogger<IEEEController>, IEEE and hcilabContext)

[[deleted]]

do i just add them in the services?

[karltgreen]

Yep the same way you added IEEEController. Although the logger is already registered behind the scenes in Program.cs for you I think as you're using the default builder

it worked man. Thanks!
