hi, I am using an Oracle MySQL database which I want to link to Visual Studio 2017 Community Edition. I installed the Oracle Developer Tools for Visual Studio 2017. I completed the installation process. I opened Visual Studio 2017 and I added a New Connection, then select "Oracle database" & "ODP.NET Managed Driver" . I received an error message "Failed to find the default tsnames.ora file". I ignored the message and in the Add Connection dialog box, I enter my settings. When I test the connection, I received an error message: ORA-12541:TNS : No Listener. Can you kindly help me to resolve this issue.
Thanks
