System.TypeLoadException Could not load type System.Configuration.SingleTagSectionHandler

This is interesting, I have attached my web.config file and the
exception I have been logging. I created a library which provide data
access to a database and a control system. The library is written in
C#. I created a small .exe file to test that the library builds
propertly from configuration and that it communicates properly. This
work great in the System.Windows.Forms. However, when I use the
library in a web enviroment things don't go so well. I copy the
unique instruction in the app.config file the the web.config file.
Bellow is the exception generated, essentially the system crashed when
it tries to load Systetem.Configuration.SingleTagSectionHandler which
I used in the web.config & app.config file.

Now WHY does the config file work in a desktop app enviroment and when
in a web enviroment I get problems! Any suggestions on how to fix the
problem would be much appreciated.

I am using the 1.1 version on the Framework.

The following is the exception which I log :

Exception: System.Configuration.ConfigurationException
Message: Exception creating section handler.

This is an example of my web.config file :

<sectionGroup name="Sorter">

type="System.Configuration.SingleTagSectionHandler " />
<section name="sp_prefix"
type="System.Configuration.SingleTagSectionHandler " />
