I have this error, any ideas?

The ObjectContextManager is trying to create an instance of your EF context object, and that's failing. Sadly the exception doesn't say why it is unable to create an instance of the EF context object - so you'll probably need to try to manually create one yourself to see why it is failing.

I will test it and let everyone knows the results

I have experienced the same problem today. I got the exception message {"Keyword not supported: 'data source'."} and this is a problem connected to the database connection string.

 It appears to have a relation to the fact that I am using the ADO.NET Entity Framework for data access. The connection string I used was a valid ADO.NET connection string - but was NOT a valid Entity Framework connection string.
