  I can confirm this is happening too, the code is exactly the same as in release 5.6.1

  Hi All,

  Could you write steps to reproduce this problem with a fresh download ? We have tried but couldn't reproduce it on our side.

  Thanks.

  I had this same issue while developing locally. I spent 8 hours on Saturday coding, building and testing and 6 hours on Sunday - absolutely no problems. Then after one build it threw this same error. I had never touched any code related to the friend service. I ended up rebooting my computer (which showed a memory error on shutdown). When I restarted and built my solution again, the problem was gone. Three more hours of building and testing - no problem. Memory leak?

  Even after two years, surprisingly same thing happened like above comment of @outdoored.

  I was spending more than two days to resolve the problem of ObjectDisposedException to access repository in my own separate console applicaiton to be used as a task scheduler job independently just to import data. I first used the exact same code of 'X.Migrator' application and just added my code in the 'MultiTenantMigrateExecuter.Run()' method to access some other reposiotry of the same database. But unfortunately I was getting same error. Even [UnitOfWork] did not work for me.

  And as last hope, I restarted my machine and suddenly after restart it is working with [UnitOfWork]! with Tenant repository onlu which is defined by Abp. But not for any other entities created by us.

  Hi all, Sorry to post on a closed topic but i have a similar problem.

  System.ObjectDisposedException Cannot access a disposed context instance. A common cause of this error is disposing a context instance that was resolved from dependency injection and then later trying to use the same context instance elsewhere in your application. This may occur if you are calling 'Dispose' on the context instance, or wrapping it in a using statement. If you are using dependency injection, you should let the dependency injection container take care of disposing context instances. Object name: 'CustomerHubDbContext'.
