I have method which have to add customer:

    [WebInvoke(UriTemplate = "/", Method = "POST", ResponseFormat = WebMessageFormat.Json)]
    [OperationContract]
    string CreateCustomer(Customer customer);

And i have a problem because all calls to this method fails!
The same method with GET working well (just return Customer object bu request id in url).
Response from wcf service:

Status: 400

 headers = {
        "Cache-Control" = private;
        "Content-Length" = 2900;
        "Content-Type" = "text/html";
        Date = "Tue, 22 Mar 2011 12:51:09 GMT";
        Server = "Microsoft-IIS/7.0";
        "X-Aspnet-Version" = "4.0.30319";
        "X-Powered-By" = "ASP.NET";
    }

  </head>
  <body>

and i cannot debug method because problem occups before step in method.

I think that problem with my first argument Customer customer
How to do POST right? And how to work with it (Parse json on server)?

In fiddler

enter image description here

 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN""http://www.w3.org/TR/html4/strict.dtd">
<HTML><HEAD><TITLE>Bad Request</TITLE>
<META HTTP-EQUIV="Content-Type" Content="text/html; charset=us-ascii"></HEAD>
<BODY><h2>Bad Request - Invalid Header</h2>
<hr><p>HTTP Error 400. The request has an invalid header name.</p>
</BODY></HTML>

but i am not sure that this is the same problem like customer have!

    I’m not entirely sure what problems you are getting, but when I looked into this, I had a different header:

    Content-Type = application/xml

    Also, you appear to have chopped off the body from your question, that could be useful.
