Something strange with UserManager's users tracking

Lavshyak commented 1 week ago

Is there an existing issue for this?

[x] I have searched the existing issues

Describe the bug

servicesScope0:
var user = new User
userManager0.CreateAsync(user

IdentityUser userToRemember;
servicesScope1:
userToRemember = userManager1.FindByIdAsync(1)

//the presence of this block does not affect the occurrence of an exception, I added it for example
serviceScope2:
tmpUser = userManager2.FindByIdAsync(1)
userManager2.UpdateSecurityStampAsync(tmpUser) // ok

serviceScope3:
userManager3.UpdateSecurityStampAsync(userToRemember) //throws InvalidOperationException exception

Expected Behavior

no exception

Steps To Reproduce

Project with code to reproduce: https://github.com/Lavshyak/AspNetIdentityUserManagerBug

Exceptions (if any)

InvalidOperationException with message: "The instance of entity type 'Account' cannot be tracked because another instance with the same key value for {'Id'} is already being tracked. When attaching existing entities, ensure that only one entity instance with a given key value is attached..."

when i do this, there is no exception: serviceScope3: mainDbContext.Attach(userToRemember)

so i don't think the problem is in DbContext

Lavshyak commented 1 week ago

and it's no matter i remember account from servicesScope0 or servicesScope1. so i think the problem is either in the UserManager from scope0 or from scope3

dotnet / aspnetcore
