MS CRM 2016 Microsoft.Xrm.Tooling.Connector OrganizationServiceProxy is null - dynamics-crm

Question

The problem is in connection to MS CRM 2016 by Xrm.Tooling.Connector. There is bug. When you get object from connection method OrganizationServiceProxy is null.
We solved this problem 2 days and on the end problem was in invalid app.config in section system.serviceModel. When we repair all errors, everything was ok. I hope this solution help to other people.

I find last CRM error in connection object. You can get the message by reflection.
public void TestInit()
{
var str = "Url=https://*****; Domain=***; Username=***; Password=****; authtype=AD;";
mysvc = new CrmServiceClient(str);
var crmConSvc = GetInstanceField(mysvc.GetType(), mysvc, "CrmConnectionService");
var logEntry = GetInstanceField(crmConSvc.GetType(), crmConSvc, "logEntry");
var lastErrorMethod = GetInstanceMethod(logEntry.GetType(), logEntry, "get_LastError");
var message = lastErrorMethod.Invoke(logEntry, null);
Console.WriteLine(message);
}
internal static object GetInstanceField(Type type, object instance, string fieldName)
{
BindingFlags bindFlags = BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic
| BindingFlags.Static ;
FieldInfo field = type.GetField(fieldName, bindFlags);
return field?.GetValue(instance);
}
internal static MethodInfo GetInstanceMethod(Type type, object instance, string methodName)
{
BindingFlags bindFlags = BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic
| BindingFlags.Static;
MethodInfo met = type.GetMethod(methodName, bindFlags);
return met;
}
