It's pretty confusing task to connect to oracle database. There are many steps to follow and I guess I followed almost everything and solved too many errors on the way. Now I'm stuck at this stage with the error 

Oracle.DataAccess.Client.OracleException: ORA-12154: TNS:could not resolve the connect identifier specified

my tnsnames.ora file

ORCL =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = orcl)
  )
)

my ORACLE_HOME path specified in environment variable

F:\app\Shuvro\product\12.1.0\dbhome_1\BIN;

my connectionstring in web.config

Data Source=ORCL;User Id=c##shuvro;Password=admin;Persist Security Info=True;

tnsping ORCL returned OK.

I'm using Visual Studio 2013 and Oracle 12c Enterprise Database. I installed ODP.NET and ODAC. Now what I'm missing here? Any help much appreciated.

modify tnsnames file to include name of your machine or IP address instead of localhost you can't rely for it to be translated correctly.

Try this (server instead of data source)

Server=ORCL;User Id=c##shuvro;Password=admin;Persist Security Info=True;

You should download and install Oracle Developer Tools for Visual Studio to connect to oracle database
