How to map entity using Dapper with postgres

Question

I’m having a big challenge here and I can’t seem to solve it.

I’m working with DDD and on the layer of Infra esotu using Dapper

When trying to execute the following code on RepositorioUsuario:

    public long Adicionar(TEntity entity)
    {
        using (var connection = _dbConnectionString.Connection())
        {
            connection.Open();
            return connection.Insert<TEntity>(entity);
        }
    }

Mapping error with the entity:

Npgsql.Postgresexception: '42703: column "Name" of "user" relation does not exist'

This error occurs because in the entity I have a property with the name Nome and if I change to nome with the tiny "N", the dapper can map.

But I don’t want to do that because I want to follow the pattern of names. I know it sounds silly, but it’s too weird to work with properties in lower case.

I’m about to leave the Dapper and using the ADO same. I don’t want to use the EF.

What should I do? try to fix it? change to ADO? there’s some rule I can’t use ADO in projects DDD?
