As I can access the tables directly, it is that with the identity I can access all the procedures as an example:
var user = await UserManager.FindByNameAsync(userName);
I use all these methods, but I see the need to call the context to bring me a list of users and the context does not bring me any table _ctx.AspNetUsers I instantiate the context but it does not bring me the table. I am doing it in a web api
I think your problem is that Webapi by default does not have the UserManager configured, so you would have to initialize it. I got the solution from here: https://stackoverflow.com/questions/24574693/how-to-access-identity-usermanager-in-web-api-controller-to-send-an-email
