i've table named educationtypes , entity named educationtype, renamed 1 of entity properties, i'm getting either parameter @objname ambiguous or claimed @objtype (column) wrong. how can solve issue?

the generated sql script:

execute sp_rename @objname = n'dbo.educationtypes.nvarchar', @newname = n'educationtypetitle', @objtype = n'column'

if you're using code first , have (an) existing migration script(s) , trying overwrite alter (i.e. renaming column) has since been deleted, you'll error output. simplest way delete migration script, add-migration via nuget, , update database.
