HttpContext.Current is null in my web service

Question

I have a web service (.svc), and I am trying to capture the SOAP request using a piece of code found elsewhere on StackOverflow.

The problem is that HttpContext.Current is null, so I can't access Request.InputString.

Why is this null, and how can it be solved?

XmlDocument xmlSoapRequest = new XmlDocument();

Stream receiveStream = HttpContext.Current.Request.InputStream;
receiveStream.Position = 0;

using (StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8))
{
    xmlSoapRequest.Load(readStream);
}

If you want to use HttpContext because the code has already been written as so; you need to add this to your web.config where your service resides:

<configuration>
    <system.serviceModel>
        <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
    </system.serviceModel>
</configuration>

Thank you. We have prebuilt classes looking for the httpcontext. FYI I also had to add the following preceding my Service class definition --> [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] – ejhost Feb 12 '15 at 20:58

From one of Microsoft's pages on the subject.

HttpContext: Current is always null when accessed from within a WCF service. Use RequestContext instead.

Correct else use below to read header

 var headers = OperationContext.Current.IncomingMessageProperties["httpRequest"];
                var apiToken = ((HttpRequestMessageProperty)headers).Headers["apiKey"];

HttpContext.Current is null when accessed from a web service. Use HttpRuntime.Cache instead.
