Asp.Net Core EF Core Error: Cannot access a dispos

ENTITY FRAMEWORK
Likes 102 Views 3944
Read Article

Asp.Net Core EF Core Error: Cannot access a disposed object. A common cause of this error is disposing a context 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, or wrapping the context in a using statement. If you are using dependency injection, you should let the dependency injection container take care of disposing context instances.
