IdentityDBContext confusion - need more samples and explanation please

[CJHarmath]

Just started looking at ASP.NET Identity recently and I got stuck with something.
There are way too many confusing stackoverflow questions about how to plug the identity user to custom entity relations.
Also identitydb context by itself is also confusing. Small things like the guid as id etc etc.

Few examples of questions worth reviewing
http://stackoverflow.com/questions/19902756/asp-net-identity-dbcontext-confusion
http://stackoverflow.com/questions/28531201/entitytype-identityuserlogin-has-no-key-defined-define-the-key-for-this-entit
http://stackoverflow.com/questions/9954997/the-member-with-identity-does-not-exist-in-the-metadata-collection-parameter-na

Most of the samples and docs are way too simple, just adding properties to the user but no relations which would be more helpful.
http://www.asp.net/mvc/overview/security/create-an-aspnet-mvc-5-app-with-facebook-and-google-oauth2-and-openid-sign-on

Can you please just do a very simple sample / update the doc to represent how to add let's say a todo list for a logged in user ? And also explain the various pros and cons flying around if one should extend IdentityDbContext and "pollute" the model project with EF dependencies etc.

It might be just me, but I was reading about this in the past few hours and it's still confusing and there seems to be no good story about this.

Disclaimer: I have not spend too much time yet with Identity, so looking at the newbie angle which is I think a very important factor.

Hopefully someone will read it and consider reviewing the docs / samples as for first timers with identity it can really be confusing. New starters should not spend hours with this and going through that many so questions...

Thanks

Hah, of course I found what I was looking for just after opening this issue
https://github.com/rustd/AspnetIdentitySample

From here
https://blogs.msdn.microsoft.com/webdev/2013/10/20/building-a-simple-todo-application-with-asp-net-identity-and-associating-users-with-todoes/

BTW, I realize it's a 2 years old blog entry, but still the style is terrible to read.

Would be nice if this topic is demonstrated more generally based on those confused stack overflow questions.
I am still not sure why didn't it work for me when I first tried, but this is a nice simple sample which is cool.

After updating to the latest nuget packages, that sample no longer works, so I wonder if you have an up-to-date version for this ? Thanks

Pretty much can't be done in this version. You'll need to use Identity 2.0 instead. There's a thread here: #585

@Rick-Anderson One for you?

@csharmath Yes this is planned. See dotnet/AspNetCore.Docs#977
I have a MVC5 version of this listed in the issue but it hasn't had a security audit so is not blessed my MSFT. I did it one afternoon.

Thanks @Rick-Anderson for looking into this!
Looking at your repo, I don't see relationship defined between the ApplicationUser and the Contact and hence the controller is not filtering either based on the logged in user.
That would be useful to have as a reference and its a more realistic sample.

Thanks again

@csharmath did you look at the right repo? https://github.com/Rick-Anderson/secureMvc only allows the logged in user to edit their records.

[Rick-Anderson]

@csharmath oops - wrong repo, let me find the right one.

[Rick-Anderson]

@csharmath it's the PR that hasn't been approved. https://github.com/Rick-Anderson/secureMvc/pull/2

[CJHarmath]

great, thanks for that! I will check later.
