Section or group name 'dotNetOpenAuth' is already defined

description

It seems that there is an extra section definition in the web.config file. After installing the required Nuget Packages and completing all required steps. When running the application the following error is thrown:

Section or group name 'dotNetOpenAuth' is already defined. This can not be defined multiple times.

In my case I could avoid this error by removing the following section definition in the web.config file (which was present before the Nuget Package installation):

<section name="dotNetOpenAuth" type="DotNetOpenAuth.Configuration.DotNetOpenAuthSection" requirePermission="false" allowLocation="true" />
