No service for type 'Microsoft.AspNetCore.Identity.UserManager`1[Models.ApplicationUser]'

[a-a-k]

I'm using LiteDB.Identity in project based on SPA (Angular) template. I changed Statup.cs as it shown in readme. The error was thrown when I tried to access protected sources (via [Authorize] attribute).
What's going wrong?

Hi @a-a-k

Thank you for using LiteDB.Identity.

Could I kindly ask you to double check connection string configuration for LiteDB:
https://github.com/quicksln/LiteDB.Identity/blob/master/sample/LiteDB.Identity.Sample/appsettings.json

Next, please check if all references have been added correctly to your project definition :
https://github.com/quicksln/LiteDB.Identity/blob/master/sample/LiteDB.Identity.Sample/LiteDB.Identity.Sample.csproj

At the very end please double check Configure section of Startup.cs if contains :

app.UseAuthentication();
app.UseAuthorization();

https://github.com/quicksln/LiteDB.Identity/blob/master/sample/LiteDB.Identity.Sample/Startup.cs

And let me know how it went.

@quicksln thank you for your reply!
All things you mentioned are same.
Okay, seems the problem is underlying deeper. I think it is in auth mechanisms which provided by SPA template. There IdentityServer and its stuff. Now I'm getting Error: Could not load settings for 'App' at AuthorizeService.js.

Hello @a-a-k

Thank you for additional information. Unfortunately, I did not have chance to try IdentityServer4
with ASP.NET Identity over LiteDb.Identity.

But according to IdentityServer4 documentation, in theory it should be possible to use both, please have a look on following links:

https://docs.identityserver.io/en/release/reference/aspnet_identity.html
https://docs.identityserver.io/en/release/quickstarts/6_aspnet_identity.html

Hope you find this helpful.

Hi, Piotr.
Looks like no deal with IdentityServer without EF is possible.
