A custom policy assertion should be created when one of the turnkey security asser tions doesn t meet the needs of your application. The custom policy assertion is used to enforce security requirements or for modifying SOAP messages. As mentioned in Lesson 1, a custom policy assertion must be derived from either the PolicyAssertion or

SecurityPolicyAssertion class. Because you ll be creating a security assertion, you ll derive yours from the SecurityPolicyAssertion class. Follow these steps to create a custom policy assertion that secures a SOAP message exchange: 1. Create a new Class Library project, rename the default class appropriately, and derive it from the SecurityPolicyAssertion class. Add two private variables, username and password, and the corresponding read-only properties for retrieving the values of the private variables. Then add two constructors, one default and parameterless, and one that accepts a username and a password. In the nonde fault constructor, save the passed username and password values to the private variables:

2. Override the abstract CreateServiceInputFilter method of the SecurityPolicyAsser tion class:
'VB Public Overrides Function CreateServiceInputFilter(ByVal context As _
Microsoft.Web.Services3.Design.FilterCreationContext) As _
Microsoft.Web.Services3.SoapFilter
Throw New Exception("The method or operation is not implemented.")
End Function
//C# public override SoapFilter CreateServiceInputFilter(FilterCreationContext context)
throw new Exception("The method or operation is not implemented.");
3. Override the abstract CreateServiceOutputFilter method of the SecurityPolicyAsser tion class:

End Function //C# public override SoapFilter CreateServiceOutputFilter(FilterCreationContext context) { throw new Exception("The method or operation is not implemented."); }
4. Override the abstract CreateClientInputFilter method of the SecurityPolicyAsser tion class:
'VB Public Overrides Function CreateClientInputFilter(ByVal context As _ Microsoft.Web.Services3.Design.FilterCreationContext) As _ Microsoft.Web.Services3.SoapFilter Throw New Exception("The method or operation is not implemented.") End Function //C# public override SoapFilter CreateClientInputFilter(FilterCreationContext context) { throw new Exception("The method or operation is not implemented."); }
5. Override the abstract CreateClientOutputFilter method of the SecurityPolicyAsser tion class:
'VB Public Overrides Function CreateClientOutputFilter(ByVal context As _ Microsoft.Web.Services3.Design.FilterCreationContext) As _ Microsoft.Web.Services3.SoapFilter Throw New Exception("The method or operation is not implemented.") End Function //C# public override SoapFilter CreateClientOutputFilter(FilterCreationContext context) { throw new Exception("The method or operation is not implemented."); }
Lesson 2: Custom Policies
6. Override the ReadXml method of the SecurityPolicyAssertion class. Although the ReadXml method isn t abstract and as such doesn t have to be overridden like other methods described previously, overriding ReadXml is necessary when con figuration is done through a configuration file. If you don t, a System.Net.WebEx ception is thrown because the operation times out, waiting for the start element to be read from the configuration file. So, in the ReadXml method, add code for parsing the custom XML elements and attributes, if any, that can be placed in the policy file for the security policy assertion. Security policy assertions (turnkey and custom) can provide an XML element that is used for specifying the options in the policy file. An XmlReader object is passed to the ReadXml method, and the reader is positioned on the XML element for the security policy assertion. The name of the XML element is specified when the security policy assertion is reg istered in the policy file with the extension element. Therefore, the XmlReader can be used to retrieve the options that are specified in the policy file:
'VB Public Overrides Sub ReadXml(ByVal reader As XmlReader, _
ByVal extensions As IDictionary(Of String, Type))
