The above bug can be solved by adding the following line in your web.config file.
--------------------------------
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="Microsoft.SqlServer.Types" publicKeyToken="89845dcd8080cc91" />
<bindingRedirect oldVersion="1.0.0.0-11.0.0.0" newVersion="10.0.0.0" />
</dependentAssembly>
</assemblyBinding>
</runtime>
--------------------------------
This forces the EntityFramework to use the version 10 of the SqlServer.Types.dll, which doesn't have the Geometry type apparently.
