Research direction
Start by reproducing the reported error with an entity using [ExplicitKey] through InsertAsync and UpdateAsync. Determine the database, schema, Dapper.Contrib version, and expected key behavior; done means the operation works without the reported "Field 'Id' doesn't have a default value" error and the behavior is covered by a regression test.
