The .NET Remoting framework is based on messages that travel through various layers. Those layers can be extended or replaced and additional layers can be added. (I discuss layers in more detail in 11.) These layers are implemented using so-called message sinks. A message will pass a chain of sinks, each of which will have the possibility to work with the message s content or to even change the message. Using the ClientProviders and ServerProviders properties in the configuration file, you can specify this chain of sinks through which you want a message to travel and the formatter with which a message will be serialized. The structure for this property for the server side is as follows: <channels> <channel ref="http" port="1234"> <serverProviders> <formatter /> <provider /> </serverProviders> </channel> </channels>

You may only have one formatter entry but several provider properties. Also note that sequence does matter. The following attributes are common between formatters and providers:

Reference for a predefined SinkProvider ( soap , binary , or wsdl ) or reference to a SinkProvider that has been defined in a configuration file. Attribute that is mandatory when ref has not been specified. Contains the exact type (namespace, class name, assembly) of the SinkProvider s implementation. When the assembly is in the GAC, you have to specify version, culture, and public key information as well.
Here are additional attributes that are optional for formatters:
Attribute
includeVersions
Description
Indicator of whether version information should be included in the requests. Takes a value of true or false (defaults to true for built-in formatters). This attribute changes behavior on the client side. Indicator of whether the server will look for the exact type (including version) or any type with the given name. Takes a value of true or false (defaults to false for built-in formatters).
strictBinding
In addition to these attributes, both formatters and providers can accept custom attributes, as shown in the following example. You have to check the documentation of your custom sink provider for the names and possible values of such properties: <channels> <channel ref="http" port="1234"> <serverProviders> <provider type="MySinks.SampleProvider, Server" myAttribute="myValue" /> <sampleProp>This is a Sample</sampleProp> <sampleProp>This is another Sample</sampleProp> </provider> <formatter ref="soap" /> </serverProviders> </channel> </channels> typeFilterLevel Attribute on Formatters Last but not least, there is one additional attribute I have to mention, the typeFilterLevel attribute, which can be applied on formatters on the server side as well as the client side. Although the attribute already existed in version 1.0 of the .NET Framework, with the trustworthy computing initiative of Microsoft and the principle of Secure By Default, the behavior of this attribute from version 1.0 to 1.1 of the .NET Framework has changed.
CHAPTER 4 CONFIGURATION AND DEPLOYMENT
When objects are sent across the wire using .NET Remoting, they have to be serialized and deserialized. That s true for both MarshalByRef objects, whereby an ObjRef is serialized, and MarshalByValue objects, whereby the whole object is serialized and deserialized. Theoretically an unauthorized and malicious client could try to exploit the moment of deserialization. Here you can find an outline of threats that might happen with deserialization of objects: If a remoting server exposes a method or member that takes a delegate, this delegate may be used to invoke methods on other types that have the same method signature. When the remoting server takes a MarshalByRef object from the client, the URL stored in the ObjRef passed from the client to the server can be tampered with so that the server calls back to malicious clients. Implementing the ISerializable interface on a serializable type means that code is executed on this type each time it is serialized and deserialized. If a malicious client passes potentially dangerous data on such types, which leads to code execution on the server during deserialization, this can result in security vulnerabilities. Often remote servers enable clients to register sponsors. But the number of sponsors that can be registered is not limited, which can lead to denial of service attacks. These are just a few threats that can be (partially) mitigated using the typeFilterLevel attribute. Basically this attribute has two possible values for type filtering by the runtime: low and full. The effects of each value are described in the following table.
