Upgrade with nuget, umbraco.datalayer wants older MySql.Data version

While upgrading with nuget you get an error that umbraco.datalayer is looking for mysql.data version 6.9.8. But nuget installs the latest MySql.Data version 6.9.9. I guess something has to be changed in umbraco.datalayer.

Please, would appreciate I you would fix this quickest as possible!

When using nuget to upgrade and I get this error message:

Server Error in '/' Application.

I tried to upgrade to 7.4.2 and got the same problem. It also installs MySql.Data version 6.9.9. It requires version 6.9.8.

Is there a work around?

Hi Jerker.

I think this is related to this issue: http://issues.umbraco.org/issue/U4-7410

Try adding the following to your web.config in the runtime section (not tested, just an idea):
```
<dependentAssembly>
    <assemblyIdentity name="MySql.Data" publicKeyToken="c5687fc88969c44d" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-6.9.8.0" newVersion="6.9.9.0" />
</dependentAssembly>
```
