first of all thanks for anyone who\'s willing to have a look at my problem. I\'m pretty new with Nancyfx and I\'m having issues with trying to bind a JSON payload to a dynamical
It sounds like you may be better off using a Dynamic type:

TheCodeJunkie has a custom model binder for Dynamic. You should be able to use this to do:
dynamic model = this.Bind();
