My code is someting like below:

Contact contact = _dbContext.Contacts.FirstOrDefault(x => x.Email == uc.Session.ContactId);

contact.Organization = "test";

_contactService.Update(contact);

and it throw error on the line of contact.Organization = "test";

please help!

Just throw some thoughts of mine to make it clearer. It is strange that the error happens on the set value.

private string _organization;
public virtual string Organization
{
get
{
return this._organization;
}
set
{
this._organization = value;
}
}

Is it some setting somewhere to block this value set?

Thanks,

Hello Winson,
You can receive such errors in case you have specified the DataAccessKindAttribute as 'ReadOnly'. Please see this link for details. 
To fix it, please review the setting for the particular field and set it to 'ReadWrite'.

I hope this information is helpful for you.
Do come back in case you need further information.
