C# -> VB: Extension Methods incorrect

[zijianhuang]

Input code

	public static class ResponseMessageExtensions
	{
		public static void EnsureSuccessStatusCodeEx(this HttpResponseMessage responseMessage)
		{
			if (!responseMessage.IsSuccessStatusCode)
			{
				var responseText = responseMessage.Content.ReadAsStringAsync().Result;
				var contentType = responseMessage.Content.Headers.ContentType;
				throw new WebApiRequestException(responseMessage.ReasonPhrase, responseMessage.StatusCode, responseText, responseMessage.Headers, contentType);
			}
		}
	}

Erroneous output

Imports System.Runtime.CompilerServices

Public Module ResponseMessageExtensions
    <Extension()>
    Public Sub EnsureSuccessStatusCodeEx(Me responseMessage As HttpResponseMessage)
        If Not responseMessage.IsSuccessStatusCode Then
            Dim responseText = responseMessage.Content.ReadAsStringAsync().Result
            Dim contentType = responseMessage.Content.Headers.ContentType
            Throw New WebApiRequestException(responseMessage.ReasonPhrase, responseMessage.StatusCode, responseText, responseMessage.Headers, contentType)
        End If
    End Sub
End Module

Expected output

    Module ResponseMessageExtensions
        <Extension()>
        Public Sub EnsureSuccessStatusCodeEx(ByVal _responseMessage As HttpResponseMessage)
            If Not _responseMessage.IsSuccessStatusCode Then
                Dim responseText = _responseMessage.Content.ReadAsStringAsync().Result
                Dim contentType = _responseMessage.Content.Headers.ContentType
                Throw New WebApiRequestException(_responseMessage.ReasonPhrase, _responseMessage.StatusCode, responseText, _responseMessage.Headers, contentType)
            End If
        End Sub
    End Module
