Silverlight: HTTP DELETE and PUT methods with RestSharp

Question

I wanted to access an internal REST API from Silverlight, but it turns out that I am not allowed to use POST or DELETE as the HTTP method for my request.

Doing so always

Answer 1

SecurityException probably means the API doesn't have the proper clientaccesspolicy.xml file in place. Here's an example of a very lenient one that allows all HTTP methods and headers. We have used this successfully for our API (which is popular, though I don't know how much traffic we get from Silverlight).

This needs to be placed in a clientaccesspolicy.xml file at the root of the domain the API you are trying to use is on.
