Hi Guys

I've read the other forum posts on this issue but just can't figure it out.

Several seconds after my app loads in Browser, I get "InvalidOperationException: Call Connect() before doing a Login".

Thing is, I am calling this. I have, in the Login() method upon Load:

private void Login()
{
       ILoginCredential credential = null;
       credential = new FormsAuthenticationLoginCredential("user", "password", "BENDESKTOP", true);

       EntityManager.ConnectAsync(op =>
       {
           EntityManager.LoginAsync(credential, LoginCompleted, null);
       });
}

If I completely remove the LoginAsync call, I still get told to Connect before logging in too. I had the app running fine for weeks, and all I did to change it was add a new project to the solution, so can't work out what's happening.

I originally had ConnectAsync and then LoginAsync separately (instead of LoginAsync call within ConnectAsync call) but the result was the same, as is to be expected I guess.

Anybody able to assist? Would be greatly appreciated. (I'm sure it's something simple).

Thanks in advance!

Cheers,
Ben

The connect call is probably failing for some reason.  Check the op.Error returned by ConnectAsync to see what's going on.

Thanks,

Have tried below, but I get nothing. I tried the boolean haserror property also, but nothing, not even a message box. If I delete the entire Login Method, i still get the exception, even though LoginAsync isn't being called anywhere in the program. It's as if the whole method is being completely ignored but Login() is called upon Page_Loaded. Weird thing is, this error only started appearing after I added a new project to the solution. This didn't change the startup project or cause and inconsistencies either.

            private void Login()
            {
                ILoginCredential credential = null;
                credential = new FormsAuthenticationLoginCredential("user", "password", "BEN-NOTEBOOK", true);

                EntityManager.ConnectAsync(op =>
                {
                    var results = op.Error.Message;
                    MessageBox.Show(results.ToString());
                    EntityManager.LoginAsync(credential, LoginCompleted, null);
                });
            }
