to the Google, they inform me of performing an illegal request.
Why is MS now also breaking other company's stuff?

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.

Looks like the exception handling is sub-optimal.

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.

I just joined this forum, so wanted to say hi! sorry if this is the wrong place for introductions, I'm new here so still figuring out how it all works!

Hello new!
I am not a number. I am a ... no, wait!

Haha .. well my name is Jade. I am looking to start a career in working for web hosting companies, and wanted to join this forum to do some research
I have an interview next week ...

Plenty to look at here!
Search[^] is a good place to start.
But...you'd probably be best off if you start by researching the company you are interviewing for, not the subject. Find out what they do, what they use, and how that relates to your experience and knowledge. Then use research to brush up your knowledge - but never to pretend you are experienced in stuff you don't know! That way may get you through the interview, but it won't let you keep the job once it becomes apparent you know little or nothing....

It was intercepted by the automated spam system and required human intervention.
We don't like spam here, and the system sometimes makes mistakes - as in this case. I let it through.
