C# MySQL On Windows Named Pipes Development Mode

While outlining the scope for a new project I’ve considered the possibility of using MySQL for budgeting purposes with respect to the potential size and growth rate of the database.

I downloaded and ran through the latest setup for MySQL on Windows (x64 although I opted for the 32 bit binaries) and popped in the MySql Connector DLL (ADO not ODBC) into my project and began whipping up some code in no time.

However, this little trick seemed to be not well known after some google searching on why MySQL Workbench (great tool btw) can connect, but my app could not.

Being a security conscious developer, when installing SQL I selected developer mode and opted for a safer named pipes connection for local development vs socket network connection looping through my localhost via TCP.

If you also selected this option, you may have had trouble getting your app to connect as well.

After searching through various (not necessarily directly related) sites, I found the answer.

See simple connection string snippet below.

Pipe=MySQL;Protocol=pipe;Host=.;Database=[yourdb];User ID=[youruser];Password=[yourpass]

To my surprise, the little note about specifying a period “.” as the host for named pipe connections was not easily found in the references below..
