PUT handler not found with serviceStack on IIS7.5

I am currently using serviceStack for creating REST based services which are hosted in a MVC web application.

So far ServiceStack has been amazing and I have achieved to get most of what I wanted to do working. All this works in IISExpress.

I have now moved over to IIS 7.5 and I get the 400 error that the PUT handler does not exist.

On IISExpress this all worked.

Any ideas?
