Third-party: EntityFramework.Exceptions: Known exceptions wrapping

[seclerp]

When the project uses EntityFramework.Exceptions, SaveChanges/SaveChangesAsync could lead to exceptions. E.g.:

context.Posts.Insert(post);
context.{caret}SaveChanges(); // Warning EFXXXX: EF Core state mutatioon could lead to exceptions

context.Posts.Insert(post);

try
{
  context.SaveChanges();
}
catch (UniqueConstraintException ex)
{
  {selstart}throw new NotImplementedException();{selend}
}

The fix should generate exception-catching blocks according to an analysis of the model and context. For example, [UniqueConstraint] or [ForeignKey] attributes could lead to UniqueConstraintException and ReferenceConstraintException respectively.

Full list of currently available exceptions:

• UniqueConstraintException
• CannotInsertNullException
• MaxLengthExceededException
• NumericOverflowException
• ReferenceConstraintException
