By default .NET looks for the exact assembly version that we reference in the provider. But, we do not do anything that locks you into that. Try adding a runtime section to your application's config file that redirects the assembly version. For example, the EntitySpaces Beta 2007.v0 MySQL provider references Connector/NET 5.0.3. If you add this after </configSections>, then you can use Connector/NET 5.0.5 downloaded from the MySQL site.

<runtime>
	<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
		<dependentAssembly>
			<!-- Redirect MySQL Connector -->
			<assemblyIdentity name="MySql.Data"
				publicKeyToken="c5687fc88969c44d"
				culture="neutral" />
			<bindingRedirect oldVersion="5.0.0.0-5.0.4.0"
				newVersion="5.0.5.0"/>
		</dependentAssembly>
	</assemblyBinding>
</runtime>

Thx to bigjoe714 for this post on getting the technique to work for ASP.NET config files by removing the "xmlns=..." from <configuration>.

Here is an example of assembly redirection using VistaDB:

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
            <!-- Redirect VistaDB Connector -->
            <assemblyIdentity name="VistaDB.NET20"
                              publicKeyToken="dfc935afe2125461"
                              culture="neutral" />
            <bindingRedirect oldVersion="3.20.1.0-3.20.1.29"
                             newVersion="3.20.1.30"/>
        </dependentAssembly>
    </assemblyBinding>
</runtime>
