When I do this manually
public class AdventureWorks : DataContext
{
public AdventureWorks(string connection) : base(connection) { }
public Table<Contact> Contacts;
}
[Table(Name = "Person.Contact")]
public class Contact
{
[Column(DbType = "int not null", IsPrimaryKey = true, IsDbGenerated = true)]
public int ContactID;
[Column(DbType = "nvarchar(8) not null")]
public string Title;
[Column(DbType = "nvarchar(50) not null")]
public string FirstName;
[Column(DbType = "nvarchar(50) not null")]
public string MiddleName;
[Column(DbType = "nvarchar(50) not null")]
public string LastName;
[Column(DbType = "nvarchar(50) not null")]
public string EmailAddress;
[Column(DbType = "int")]
public int EmailPromotion;
[Column(DbType = "bit")]
public byte NameStyle;
[Column(DbType = "varchar(40)")]
public string PasswordHash;
[Column(DbType = "varchar(40)")]
public string PasswordSalt;
}
I can use something like this
AdventureWorks db = new AdventureWorks("Integrated Security=sspi");
Contact cont = db.Contacts.Single(c => c.ContactID == 1280);
But If I rely on LINQ surface (designer), drag and drop contact table on the dbml file , I can see db.Contacts, but can not see the "db.Contacts.Single" method.
Is there anything to do with dbml property configiuration?
Please advise.
Thanks a lot.
