Hi,

We have the following entities:

-Account:
*Id - Guid
*Data - String

-Logins:
*Id - Guid
*AccountId - Guid
*Sucess - bool

It's not strctly like this but it's enough for explanation of the error. I'm creating like this (Accounts is abstract for several entities):

Create var of accountType (it insert alone correctly and same for login, but when inserting then in same context it throws errors).

var login = new Login() { Id = Guid.NewGuid(), Time = DateTime.Now, IP = "0.0.0.0" };
login.Account = accountType1;
context.Logins.InsertOnSubmit(login);
context.SubmitChanges();

It throws error Unmapped classmember Account, Logins.

Generally, this exception specifies that the mapping provided for your DataContext class has no information about the Account.Logins navigation property. Could you please specify the following:
- the definitions of the Account and Login classes;
- the mapping mode (attribute, file, or fluent) you are using for them;
- the stack trace of the exception.
If possible, please send us a model with which the problem can be reproduced.
