EntryPointNotFoundException when running EConnect sample console app

Question

I'm trying to run an EConnect sample console app but it keeps coming up with System.EntryPointNotFoundException in mscorlib.dll. I can't for the life of me figure out why its doing this, especially because I have successfully ran this app in the past and now all of a sudden it doesn't work.

Any ideas what could be causing this problem or at least some ideas how I could get more information about the problem. Im not sure how to catch the exception and display more info because the exception seems comes up without going into the catch block.

Here is the code for the app Im trying to run, I've tried tracing through it and it seems like the exception is occuring around this line: e.CreateEntity(sConnectionString, sCustomerDocument);

using System;
using System.IO;
using System.Xml;
using System.Text;
using System.Xml.Serialization;
using Microsoft.Dynamics.GP.eConnect;
using Microsoft.Dynamics.GP.eConnect.Serialization;

I have also reinstalled eConnect numerous times, and like I said before this was all working perfectly fine until today so I dont know whats going on. Any help on this would be greatly appreciated.

EDIT: Well, I found my issue, turns out I had the Just My Code debugging option turned off, turned that back on and it works again

Answer 1

All fixed, I had the Just My Code debugging option turned off, turning it back on fixed the issue. For anyone else with the same problem all I did was go to Tools>Options>Debugging>General>check Enable Just My Code
