It looks to me like you have references to both the Compact Framework and the standard framework MySQL libraries in your project. You need to remove the references to the ones that have .CF in their filename.

Check your web.config file assemblies section for multiple references:

<compilation>
  <assemblies>
    ...             
  </assemblies>
</compilation>

If there is more than one then remove it (the one not in the GAC, I would say off-hand.)

Also, as @Abe suggests, delete the temporary files under the following path:

c:\Windows\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\
