Hello Experts,
This has been bother me for a couple days and I can't figure it out.  I am trying to create a WCF Webservice with a Post command.  This needs to except an xml as a parameter and return a string.  When I run my service in the browser i get end point not found. When I run from a test application i get "The remote server returned an error: (404) Not Found." I am really not sure what I am doing wrong or how I should be calling this service.  My code is below:

Imports System.ServiceModel
Imports System.ServiceModel.Web
Imports System.IO

' NOTE: You can use the "Rename" command on the context menu to change the interface name "IloginReq" in both code and config file together.
<ServiceContract()>
Public Interface IloginReq

   
    <OperationContract(Name:="PostSampleMethod")>
  <WebInvoke(Method:="POST", UriTemplate:="PostSampleMethod/[New]", ResponseFormat:=WebMessageFormat.Xml, RequestFormat:=WebMessageFormat.Xml, BodyStyle:=WebMessageBodyStyle.Bare)> _
    Function PostSampleMethod(data As Stream) As String

End Interface

Imports System.Web.Script.Serialization
Imports System.IO
Imports System.Xml

<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)> _
Public Class loginReq
    Implements IloginReq
   
    Public Function PostSampleMethod(data As Stream) As String Implements IloginReq.PostSampleMethod
        ' convert Stream Data to StreamReader
        Dim reader As New StreamReader(data)
        ' Read StreamReader data as string
        Dim xmlString As String = reader.ReadToEnd()
        Dim returnValue As String = xmlString
        ' return the XMLString data
        Return returnValue
    End Function

End Class

'''Web config File

<?xml version="1.0"?>
<configuration>
  <appSettings/>
  <system.web>

    <httpRuntime requestPathInvalidCharacters="" requestValidationMode="2.0"  relaxedUrlToFileSystemMapping="true" />
    <compilation debug="true" strict="false" explicit="true" targetFramework="4.0"/>

    <modules runAllManagedModulesForAllRequests="true"/>

So you are trying to use it as a restful API?

Yes we have to use a restful web service with a post command to interface with another companies system.  I wouldn't be using this method if I had any other options as I am very new to restful webservices.  Basically we have it setup on IIS ready to go and if I use a WebGet instead of WebInvoke it works, but we have to use WebInvoke with a "Post"

Try removing the uritemplate and see if it works.

Since you are using VS 2012, why don't you use Web API? Working with REST is much easier in Web API than in WCF. There are several tutorials on the official ASP.NET website.
