Sorry to send you on a wild goose chase, the problem is @p{(bf}NOT@p{bf)} CRLF issues. @p{par}

The problem is in your HTTP headers; you're sending the request as: @p{par}

Content-Type: application/x-www-form-urlencoded @p{par}

The correct Content-Type for @p{(link}JSON-RPC over HTTP@p{link)} is: @p{brk}
  Content-Type SHOULD be 'application/json-rpc' but MAY be 'application/json' or 'application/jsonrequest' @p{par}

I'm not sure what .net is doing with the body of the request, but by the time it gets to Bitcoin/PostBin, it has x-www-form-urlencoded it enough to confuse the heck out of them. @p{par}

When you get this working, please update this thread, and for extra positive karma, add a .net section to the @p{(link}Bitcoin JSON-RPC@p{link)} wiki page. @p{brk}
