NameDescription
System_CAPS_pubmethodXmlFormatExtensionPrefixAttribute()

Initializes a new instance of the XmlFormatExtensionPrefixAttribute class.

System_CAPS_pubmethodXmlFormatExtensionPrefixAttribute(String, String)

Initializes a new instance of the XmlFormatExtensionPrefixAttribute class, setting the XML namespace and XML namespace prefix for a service description format extension.

NameDescription
System_CAPS_pubpropertyNamespace

Gets or sets the XML namespace associated with a service description format extension.

System_CAPS_pubpropertyPrefix

Gets or sets the XML namespace prefix associated with a service description format extension.

System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription
System_CAPS_pubmethodEquals(Object)

This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodGetHashCode()

Returns the hash code for this instance.(Inherited from Attribute.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodIsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethodMatch(Object)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfoCount(UInt32)

Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

A service description format extension extends how a service description is generated for an XML Web service created using ASP.NET. Specifically, a service description format extension adds XML elements to the service description. This is useful when a SOAP extension is built to run on both the client and server side of an XML Web service, as information about SOAP extensions is not placed in the service description. If you add information about the SOAP extension to the service description, a client can interpret that it must run the specific SOAP extension. An example of a SOAP extension that must run on both the client and server is an encryption SOAP extension. If an encryption SOAP extension runs on only the server, and it encrypts return values before sending them back to the client, the client must have the SOAP extension running to decrypt the SOAP message. Otherwise, the client cannot process the return value.

Use the following steps to build a service description format extension:

  1. Build a class that derives from ServiceDescriptionFormatExtension.

  2. Apply an XmlFormatExtensionAttribute to the class and specify the extension points at which the service description format extension should run.

  3. Optionally, apply an XmlFormatExtensionPointAttribute to the class and specify a member within the class that acts as a new extension point.

  4. Optionally, apply an XmlFormatExtensionPrefixAttribute to the class and specify the XML namespace prefix to be associated with XML elements generated by the service description format extension.

  5. Configure the service description format extension to run within the serviceDescriptionFormatExtensionTypes section of the configuration file.
