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

Using Umbraco And Getting Started

Umbraco 7

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>
```
