Only Int32, Int64 and Guid key fields support automatic value generation. This exception is thrown when automatic key generation is enabled for a key property but the property type doesn’t support this feature,

Solution:

use an integer or GUID property as a key field;
disable automatic key generation for a property and set an object’s key manually.

To enable/disable automatic key generation for a property use the autoGeneration parameter of the property’s KeyAttribute attribute.
