Web Services / WCF

Hi all...

I have a problem with my small Application that needs to conect to a MySQL server based on Centos Linux.

I have read here in VBForums.com many posts about the security risks of app.config file... encrypted or not... for storing the connection strings of a remote database.

OK! I agree with this... but... how can i make a VB.NET Application to connect to my database thru WebService or WCF as long my server is Centos with MySQL ? How can i make the connection strings of MySQL Connector to work with WebServices or WCF ?

I did not find any solution for this problem.

My app needs to populate a DataGridView... retreive data and post data on MySQL db...

Anyone can help me with some ideeas ?

No one can help me with this ?
