I've faced a problem that is:

An exception of type 'System.ArgumentException' occurred in EntityFramework.dll but was not handled in user code

Additional information: The Include path expression must refer to a navigation property defined on the type. Use dotted paths for reference navigation properties and the Select operator for collection navigation properties.
How can I solve it?

Solution 1

You can debug and check exactly where the error occurred and what caused it.
That would be the easiest way to find the error.

Your exception message is not a "solution" to someone else's question.

If you want to ask a question, then ASK A QUESTION[^]. But you'll need to provide a lot more information than you have here if you want anyone to be able to help you.
