How do I stop d4p1 being a required namespace prefix within my WCF service SOAP request XML -

i've built first ever wcf service designed receive http post requests have message body in strict format have no influence over. here example:

<s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">   <s:body>     <acquirepackagingdata xmlns="mydomain.com">       <account xmlns="http://schemas.microsoft.com/v1.0">         <assetidentifier>ergegdgsdyeryegd</assetidentifier>       </account>     </acquirepackagingdata>   </s:body> </s:envelope> 

the bit change each request value of assetidentifier.

my wcf service contract follows:

to given myself maximum control on xml, have opted use xmlserializer instead of datacontractserializer using [xmlserializerformat] .

the account class simple to: [xmlroot(namespace = "http://schemas.microsoft.com/v1.0")] [serializable] public class account {

    private string m_assetidentifier;      [xmlelement]     public string assetidentifier     {         { return m_assetidentifier; }         set { m_assetidentifier = value; }     }   } 

the problem occurs when make request service. when use wcf test client can see has made following request:

<s:envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">   <s:header>     <action s:mustunderstand="1" xmlns="http://schemas.microsoft.com/ws/2005/05/addressing/none">http://schemas.microsoft.com/drm/2007/03/protocols/ilgicontentprotection/acquirepackagingdata</action>   </s:header>   <s:body>     <acquirepackagingdata xmlns:i="http://www.w3.org/2001/xmlschema-instance" xmlns="http://schemas.microsoft.com/drm/2007/03/protocols">       <challenge xmlns:d4p1="http://schemas.microsoft.com/drm/2007/03/protocols/acquirepackagingdata/v1.0">         <d4p1:assetidentifier>ergegdgsdyeryegd</d4p1:assetidentifier>       </challenge>     </acquirepackagingdata>   </s:body> </s:envelope> 

note presence of d4p1 namespace aliases have been introduced. if request service request xml not include these aliases request fails null pointer on account object received acquirepackagingdata method.

i tried using datacontractserializer had same problem. hoped i'd different result using xmlserializer. read elsewhere on forum maybe use following approach made no difference:

[system.serializableattribute()] [system.xml.serialization.xmltypeattribute(anonymoustype = true, namespace = "http://schemas.microsoft.com/v1.0")] [system.xml.serialization.xmlrootattribute(namespace = "http://schemas.microsoft.com/v1.0", isnullable = false)]  public class account { .... } 

please can let me know how can modify service request xml includes namespace not pesky d4p1 aliases?

thanks
