Verification fails for one or more entities. For more information, see the EntityValidationErrors property.

Modifications:

Turn off the ValidateOnSaveEnabled switch before SaveChanges

You can turn it off like this at the Controller level

Login is visible.

Or at the DAL layer, which is closed to the entire system

Login is visible.

After closing, this error is not reported, and another error is reported instead:

SqlException (0x80131904): String or binary data will be truncated. The sentence has been terminated.

This is the problem, so to speak, when you are working with the database, there are fields that exceed the size limit of your fields in the database

Looking at the code, there are indeed fields that are too long.

Error causes:

1. Non-empty columns do not insert values incorrectly

2. The length of the foreign key column between multiple tables is different

3. The ef context object db is empty

4. EF context setting property to db. Configuration.ValidateOnSaveEnabled = false;

5. The content length exceeds the maximum column length

The reason for my error is that the name length size exceeds the limit.
