Generated wsdl file contains strange message names. WCF

Question

In generated wsdl file (form WCF service) there is a strange name template (maybe only for me). For example section describing a method:

<wsdl:message name="InterfaceName_MethodName_InputMessage">
    <wsdl:part name="parameters" element="tns:MethodName"/>
</wsdl:message>

How can i force WCF not to generate InterfaceName prefix and InputMessage postfix? The same situation is in OutputMessage case. I want wsdl to look as shown below:

<wsdl:message name="MethodName">
    <wsdl:part name="parameters" element="tns:MethodName"/>
</wsdl:message>

You can change the message element with MessageContract.Supposed your method in the interface looks like this:

<OperationContract>
Function methodName(param as String) as Integer

Then you must change it to:

<OperationContract>
     Function methodName(param As messageInput) As mesageOutput

Add these classes:

<MessageContract()> _
    Public Class messageInput

    Private input1 As String

    <DataMember(Name:="input")> _
    Public Property input() As String 
        Get
            Return Me. input1
        End Get
        Set(ByVal value As String)
            Me. input1 = value
        End Set
    End Property

End Class

<MessageContract()> _
Public Class mesageOutput

    Private return1 As Integer

    <DataMember(Name:="return")> _
    Public Property return() As Integer
        Get
            Return Me. return1
        End Get
        Set(ByVal value As Integer)
            Me. return1 = value
        End Set
    End Property

End Class

Now your message element has change to this:

<wsdl:operation name="methodName">
    <wsdl:input message="messageInput"/>
    <wsdl:output message="messageOutput"> 
</wsdl:operation>

Edit1:

To change the method name and the action Attribute do this in the interface:

<OperationContractAttribute(Action:="actionName", name:="manipulateMethodName" ReplyAction:="actionResonseName")> _
Function methodName(param As messageInput) As mesageOutput
