It has nothing to do with MS. Google search is rejecting your query because the search text is too large. But you probably knew that. Smile | :)

Looks like the exception handling is sub-optimal. Dead | X|

They are far more chance that the problem is in your own code... An object seems to be disposed twice! Maybe your connection? Maybe your code does not properly handle some events that occurs in a way you did not expect?

OK, time for a random guess of what your code looks like:

public Foo GetFoo(int id)
{
    using (var context = new YourDbContext())
    {
        return context.Foos.FirstOrDefault(foo => foo.Id == id);
    }
}
...
Foo foo = GetFoo(42);
Bar bar = foo.Bar;

You've retrieved an entity instance without loading any of its related entities. You've then disposed of the DbContext before trying to load a related entity. The lazy-loading proxy that EF created for your entity is then trying to load the related entity from the database, using the previously-disposed DbContext.

You can either turn off lazy loading, in which case the navigation property will return null; or you can explicitly load the related entities before you dispose of the DbContext; or you can use the Include extension method to eagerly load the related entities at the same time as the main entity.
Entity Framework Loading Related Entities[^]

And now, you've managed to sneak a programming question into the Lounge! Laugh | :laugh:
