How to config ODP.net in visual studio

After installing the ORACLE ODP.NET, I met THE ORA-12154:tns: cound not resolve the connect identifier specified MESSAGE.

To resove this, need to config the connection details(you can get the dialog through visual studio - > tools -> connect to database) correctly.

Data source:  Oracle Database(Oracle ODP.NET)

Connection details,
Data source name: localhost/xe  
comments: the format is machine name or ip/sid  , no space between them

user name: oracle user name, should have create session privilege
password: the password for that user
