Hi Friends,
 
Customer
{
customerid integer,
userid integer,
DOB timestamp
}
 
User
{
userid integer,
username varchar(100),
password varchar(100),
firstname varchar(50),
lastname varchar(50),
email varchar(100),
isactive bit
}
 
For username and password are updated on new mode.
 
The following statement to used to update on edit mode, but i am getting exception
 
First Way,
 
Customer editCustomer = DB.Customers.First(c => c.customerid == customerId);
if (editCustomer != null)
{
	User editUser = DB.Users.First(u => u.userid == editCustomer.User.userid);
	if (editUser != null)
	{
		editUser.firstname = userData.firstname;
		editUser.lastname = userData.lastname;
		editUser.email = userData.email;
		editUser.isactive = userData.isactive;
	}
	customerData.User = editUser;
	customerData.DOB = <input date>;
	editCustomer = customerData;
	DB.SaveChanges();
}
 
Second Way,
Customer editCustomer = DB.Customers.Include("User").Where(c => c.CustomerID == customerId).First();
if (editCustomer != null)
{
	editCustomer.User.FirstName = userData.FirstName;
	editCustomer.User.LastName = userData.LastName;
	editCustomer.User.Email = userData.Email;
	editCustomer.User.IsActive = userData.IsActive;
	DB.SaveChanges();
}
When i use second way the following exception shows,
"Entities in 'xxx.Customers' participate in the 'FK_Customer_User' relationship. 0 related 'User' were found. 1 'User' is expected."
 

 
What i did the mistake this execution?
