Why Isn\'t My MySQL Data Source Showing Up in Visual Studio?

Troubleshooting MySQL Data Source Absence in Visual Studio

Many developers encounter the perplexing issue of MySQL not appearing as a data source in Visual Studio despite installing the ADO.NET connector. This article investigates potential causes and presents viable solutions to resolve the problem.

Incorrect Connector Version

One possibility is that an incompatible connector version may have been installed. The user in the given problem statement downloaded the connector from a valid source, but an older version might have resolved the issue.

Solution: Uninstall the latest connector and install the older version (6.6.5) instead.

Visual Studio Compatibility

Another potential factor to consider is the compatibility between the MySQL connector and the specific Visual Studio version being used. In earlier versions like Visual Studio 2010, using the latest connector may have caused compatibility issues.

Solution: Ensure that the connector is registered with the relevant Visual Studio versions during installation. Select the corresponding checkboxes in the "Modify Product Features" section of the MySQL installer.

Installing Connector and Plugin Separately

In some cases, installing the MySQL server and its associated connector and Visual Studio plugin as part of a single package may not yield the desired outcome.

Solution: Uninstall the connector and Visual Studio plugin. Download them individually and install them separately.

Note on Visual Studio Express

While the original poster expressed concern about MySQL support for Visual Studio Express, it is worth noting that MySQL has since officially supported Visual Studio Community, which is the successor of Visual Studio Express.
