Open the sample that comes with ECO:

Open up the sln and ignore/ok this:

You will see this:

The ReadMe explains the missing projects but since you are a developer, you may probably not read it.

Delete the missing projects and add new references to MonoAndroidApplication1.

Choose browse and find the assemblies you downloaded in the PhoneBuilds.zip

Define what to start:

Hit F5 – three windows pop up (the phone emulator starts slowly).

This is a simple WPF UI that shows the information in our “database”.

This is the Root directory of our PersistenceServer:

This is the Phone App:

Press the first of the X buttons at the bottom of the Phone App.

The code on the phone: 

private void ApplicationBarIconButton_Click(object sender, EventArgs e)
        {
            EcoServiceHelper.GetPersistenceService(_ecospace).Refresh(true);
            EcoServiceHelper.GetAsyncSupportService(_ecospace).PerformTaskAsync(new Action(() => { 
                IObjectList list = EcoServiceHelper.GetOclPsService(_ecospace).Execute("Class1.allinstances->select(a|a.Class2->notempty)");
                int noOfC1ThatHasC2s = list.Count;
                string extra = "";
                if (list.Count > 0)
                    extra = list[0].GetValue<Class1>().Attribute1;

                int noOfC1 = EcoServiceHelper.GetExtentService(_ecospace).AllInstances<Class1>().Count;

                EcoServiceHelper.GetAsyncSupportService(_ecospace).DispatchTaskToMainThread(new Action(() => { 
                    // UI Stuff - everyone is happy to see that we do this in the main thread
                        ContentStack.Children.Add(new TextBlock() { Text = "db updated, Now C1 Total: " + noOfC1.ToString() + ",\r\n Total of C1 that has C2's " + noOfC1ThatHasC2s.ToString() + " " + extra });

                }));
            }));
        }

The code makes use of some ECO services.

The other button:

Code:

private void ApplicationBarIconButton_Click_1(object sender, EventArgs e)
{

    Class1 c1 = new Class1(_ecospace);
    c1.Attribute1 = "Created on WindowsPhone " + DateTime.Now.ToLongTimeString();
    ContentStack.Children.Add(new TextBlock() { Text = "c1 created" });

    _ecospace.UpdateDatabase();

     
}

We switch back to the WCF app and hit Refresh:

You can play around with the WPF app and the Phone App to ensure that objects created in one client can be seen in the other client after a Refresh.

If things do not work, consult the WCF troubleshoot.

For now, that is all I am going to show you about the WindowsPhone. Disappointed? Don’t be – we did a lot. We saw strongly-typed, model-driven business objects on the phone with a WCF connection to the server – that persists everything and lets you find what is on the server.
