“用户”登录失败。”

Question

I have a WCF service, I added a database, I'm using EF, but when I try to connect to the database I have this problem...

public Producenci GetProducent(int id)
{
    dbMagazynierEntities context = new dbMagazynierEntities();
    context.Database.Connection.Open();

    var producent_entity = (from p in context.Producenci
                            where p.ID == id
                            select p).FirstOrDefault();

    context.Dispose();

    if (producent_entity != null)
    {
       return TranslateProducentEntity2Producent(producent_entity);
    }
    else
    {
       throw new Exception("error");
    }
}

I get

Login failed for user '.'

this is my CS

<connectionStrings><add name="dbMagazynierEntities" connectionString="metadata=res://*/MagazynierEntity.csdl|res://*/MagazynierEntity.ssdl|res://*/MagazynierEntity.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=PIOTR-TOSH\Piotr;initial catalog=dbMagazynier;integrated security=false;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" /></connectionStrings></configuration>

Answer 1

Your connection string has

integrated security=false;

So in that fashion you should specify the user id and password in the connection string.
