Send Data Using the WebRequest Class to DotNetOpenAuth website
- by Denis
I am trying to send data to DotNetOpenAuth website as described here http://msdn.microsoft.com/en-us/library/debx8sh9.aspx
Sender receive (500) Internal Server Error. The same code for blank website without DotNetOpenAuth works fine. Should I tweak something?
Here is an exception:
System.ArgumentNullException was unhandled by user code
Message="Value cannot be null.\r\nParameter name: key"
Source="mscorlib"
ParamName="key"
StackTrace:

Exception occurs on last line of the code:
private void context_AuthenticateRequest(object sender, EventArgs e)
{
// Don't read OAuth messages directed at the OAuth controller or else we'll fail nonce checks.
if (this.IsOAuthControllerRequest())
{
return;
}
if (HttpContext.Current.Request.HttpMethod != "HEAD")
{ // workaround: avoid involving OAuth for HEAD requests.
IDirectedProtocolMessage incomingMessage = OAuthServiceProvider.ServiceProvider.ReadRequest(new HttpRequestInfo(this.application.Context.Request));
