Silverlight, "The type or namespace name 'CookieContainer' does not exist in the namespace 'System.Net'"

Question

I'm running VS2010 pro, and I downloaded a sample Silverlight app (found here: http://tinyurl.com/26brhfx) written in an older version. I did the conversion but now when I go to run it, I get this error. I searched the net, the only recommendation I found was to add a reference to "System.Net" (which didn't make sense, but I did anyway), but this didn't help. The offending code:

public System.Net.CookieContainer CookieContainer {...

Answer 1

The System.Net dll is usually referenced by default but perhaps it wasn't in the older project. Check the version number is 2.0.5.0 and that the file path is something like:-

c:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\Silverlight\v4.0\System.Net.dll
