What does An exception of type 'System.Data.Entity.Core.EntityCommandExecutionException' occurred in... mean?

Question

ASP.NET

Hello!
I don't quite understand what the following error means:

An exception of type 'System.Data.Entity.Core.EntityCommandExecutionException' occurred in EntityFramework.SqlServer.dll but was not handled in user code

The fact is that it appeared in that part of the code where nothing was changed. (But I'm starting to doubt it).
Thank you very much for your help.

Answer 1

Alternatively, the model does not match the database. Ef to the console and logs displays queries to the database, try to execute the query on the database.

Answer 2

The error was in the table name in the database.
