Entityframework recursive query triggering Exception

Asked

When performing the query with recursion an Exception is occurring:

Equipe.RelatorioRH.Single(x => x.IdRodada == IdRodada)

'Entityframeworkdynamicproxies-Model' metadata is invalid. If you are debugging a mini-dump, you can fix the problem by collecting a new mini-dump with heap and evaluating the expression again. Model.Reportariorh

Would anyone know what this is about? How to solve this?

When you use the method Single() and the query does not return 0 or more than 1 record, an Exception occurs. Make sure that’s what happened.

If the field you are looking for is a key Primary, you can use the Find(), for example.

    Thank you for the reply. I described below as a response the solution I found. Unfortunately the feedback the IDE gave describing the error confused the interpretation of the problem.

I found out what was going on.

A method that calls a second method that in turn called the first again. This caused the Exception. Unfortunately Visual Studio described that way hindered the understanding of the problem.

  • That’s not an answer.
