    <p>The trick to solving this was:</p> <ol> <li>Add references to the <code>MySql.Data</code> and <code>MySql.Data.Entity</code> libraries of the correct version (6.7.4.0 for .NET 4.5, in my case) to the project.</li> <li>Edit <code>machine.config</code> with your editor run as administrator, and replace all occurences of MySQL version <code>6.6.5.0</code> by <code>6.7.4.0</code>.</li> </ol> <p>For the second step, note that there are multiple <code>machine.config</code> files, one for each framework version (3.0, 3.5, 4.0) and architecture (32-bit, 64-bit). Also note that the <code>machine.config</code> file for .NET 4.5 is in the .NET 4.0 folder. You can find the <code>machine.config</code> files in:</p> <blockquote> <p>C:\Windows\Microsoft.NET\Framework\\Config</p> </blockquote> <p>And:</p> <blockquote> <p>C:\Windows\Microsoft.NET\Framework64\\Config</p> </blockquote> <p>If there are no references to MySQL in the <code>machine.config</code> file, you might not have installed <a href="https://dev.mysql.com/downloads/windows/installer/" rel="noreferrer">MySQL for Visual Studio</a>. Either do that, or add the following to the <code>app.config</code> file of your project:</p> <pre><code>&lt;system.data&gt; &lt;DbProviderFactories&gt; &lt;add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.7.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" /&gt; &lt;/DbProviderFactories&gt; &lt;/system.data&gt; </code></pre> <p>Note however, that when you both install <code>MySQL for Visual Studio</code> <em>and</em> add the above snippet to your <code>app.config</code> file, then you'll get this exception:</p> <blockquote> <p><strong>ConfigurationErrorsException</strong>: Column 'InvariantName' is constrained to be unique. Value 'MySql.Data.MySqlClient' is already present.</p> </blockquote>

    1. COChanging the version to '6.7.4.0' worked in the machine.config. This must be an installer bug, as 6.7.4 was installed on a fresh installation of Windows, but the reference to 6.5.5 was still written to the machine.config.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
