Missing DbContext about aspnetcore.identity.mongodbcore

[alexandre-spieser]

yeah but it's not a 5 minute job 😄

Oh I see, do you plan to migrate to net core 3?

Hello,

The concept of DbContext does not exist with MongoDb, since the DbContext is EF/SQL specfic.
In the docs available here, you can created a MongoDbContext:
https://github.com/alexandre-spieser/AspNetCore.Identity.MongoDbCore/blob/master/README.md

Configuration

To add the stores, you can use the IdentityBuilder extension like so:

services.AddIdentity<ApplicationUser, ApplicationRole>()
	.AddMongoDbStores<ApplicationUser, ApplicationRole, Guid>
	(
		"mongodb://localhost:27017",
		"MongoDbTests"
	)
	.AddDefaultTokenProviders();

It is also possible to share a common IMongoDbContext across your services (requires https://www.nuget.org/packages/MongoDbGenericRepository/):

var mongoDbContext = new MongoDbContext("mongodb://localhost:27017", "MongoDbTests");
services.AddIdentity<ApplicationUser, ApplicationRole>()
	.AddMongoDbStores<IMongoDbContext>(mongoDbContext)
	.AddDefaultTokenProviders();
// Use the mongoDbContext for other things.

You can also use the more explicit type declaration:

var mongoDbContext = new MongoDbContext("mongodb://localhost:27017", "MongoDbTests");
services.AddIdentity<ApplicationUser, ApplicationRole>()
	.AddMongoDbStores<ApplicationUser, ApplicationRole, Guid>(mongoDbContext)
	.AddDefaultTokenProviders();
// Use the mongoDbContext for other things.

Alternatively a full configuration can be done by populating a MongoDbIdentityConfiguration object, which can have an IdentityOptionsAction property set to an action you want to perform against the IdentityOptions (Action<IdentityOptions>).

The MongoDbSettings object is used to set MongoDb Settings using the ConnectionString and the DatabaseName properties.

The MongoDb connection is managed using the mongodb-generic-repository, where a repository inheriting IBaseMongoRepository is registered as a singleton. Look at the ServiceCollectionExtension.cs file for more details.

Hi,

Thanks for your full answer, I already do that but when I build I have a missing DbContext error, it's the reason why I throw this issue!

Thank you

Are you using Identity 2.0 ? This package does not support Identity 3.0.
Also, make sure that you do not have an EntityFramework packages doing Identity related work.
The stores used must only be the MongoDb ones, make sure you do not have any UserStore needing a DbContext.
You can look at the example of a Startup.cs here:
https://github.com/alexandre-spieser/AspNetCore.Identity.MongoDbCore/blob/master/sample/MongoIdentitySample.Mvc/Startup.cs

I use net core 3 ^^

[alexandre-spieser]

yeah that might be the reason why it's not working, Identity 3.0 is almost a full rewrite, because they integrated the Identity Server package, the data access layer is totally different. This package does not support it yet.

So interestingly, I've got it to compile and run using .net Core 3.1, but 26 tests seem to be failing (most seem to be related to the SecurityStamp). I'm not sure of the impact of those 26 tests failing but, its something.
