title: Using Entity Framework with Oracle
body: <p>I installed the 32 bit version of ODAC (11.2.0.2.50) from <a href="http://www.oracle.com/technetwork/topics/dotnet/downloads/oracleefbeta-302521.html" rel="nofollow noreferrer">here</a> in an attempt to use the Entity Framework with Oracle.</p>
  
  <p>As soon as this is installed my data connection to the database fails in Server Explorer with the following error:</p>
  
  <blockquote>
    <p>ORA-12154: TNS:could not resolve the connect identifier specified</p>
  </blockquote>
  
  <p>I can fire up TOAD and view my database fine, however when I was in there I clicked on the 'Home Editor' and was presented with this:</p>

  <p>which I can only assume is related somehow.  I checked with the answer <a href="https://stackoverflow.com/questions/6058744/problem-on-using-odp-net">listed here</a> but to no avail.</p>
  
  <p>Any ideas as to the issue?</p>
