ADO to SQL Client need Oracle Connection String

I am upgrading from NAV 2009 R2 to NAV 2016. I have some processes that used ADO to connect to an Oracle database but in NAV 2106 I am using the dotnet SQLClient to do this. Works fine with SQL connections but can't get it working with an Oracle connection.

Here is what I used in NAV 2009 for the connection string (with ADO):
Provider=MSDAORA.1;Password=mypassword;User ID=myuserid;Data Source=mydatasource;Persist Security Info=True (mydatasource is the odbc connection set up on the machine)

What would the connection string be now that I am sue the dotnet sql client?
