Authentication - Context and Layout Location Best Practices / Targeting Context

Dean Everhart 1,541

Two Questions:

1. I want to resolve the error below

2. I mirrored the Views.Shared._Layout.cshtml and Data....Context.cs hierarchy within the Areas.Identity folder (see: Solution Explorer below) ...the thought being to keep Authentication concerns separate from the project. This maynot (probably is not) the best way to go about this; should I / how should I organize this differently?

Question: What is the best practice for location of the layout and context items for a project?

Error: User's image

Solution Explorer: User's image

Thank you.

You created two different Identity DB contexts. One is AuthenticationTutorial.Areas.Data.AuthenticationTutorialContext and the other is AuthenticationTutorial.Data.ApplicationDbContext What is the reasoning behind designing two separate Identity contexts in a single project?

If this is a mistake, then I would start over and NOT create a second DbContext while scaffolding the Razor Pages. Just use the existing DbContext. I think providing assistance will be much easier if you can explain the overall goal.

Thanks for the response. I'll create with single context file.

Rationale: Separation of Concerns

Re: Below: As for the best place, for a dbcontext, would be its own project.

I think you misunderstand. You created two Identity DbContext classes in a single project.
It does make sense to separate a user account data store if login services are centralized. For example SSO.

With c# code, the folder structure does not matter. Only the namespace and object names. While it’s common for the namespace to match the folder structure, it’s not a requirement. Most likely your dbcontext namespace does not match. As for the best place, for a dbcontext, would be its own project.
