Setting the type of a table's primary key to an enum type causes "Update Model From Database" to fail with the error "Specified cast is not valid".

Reproduction with Entity Developer 7:

1. Create the following MySQL table:

   Code: Select all

   CREATE TABLE `TestTable` (
       `Id` INT(10) NOT NULL AUTO_INCREMENT,
       PRIMARY KEY (`Id`) USING BTREE
   )
   COLLATE='utf8mb4_unicode_ci'
   ENGINE=InnoDB;

2. Create a new EF Core model using default settings (database first, adding TestTable to the model, etc)
3. Add a new enum type using default settings
4. Change the type of TestTable.Id to the new enum type
5. Click Model->Update Model From Database
6. Click next

"Specified cast is not valid."
