Specifies whether an additional check of progress of the XmlSerializer is done.
<xmlSerializer checkDeserializerAdvance = "true"|"false" />
Attributes and Elements
The following sections describe attributes, child elements, and parent elements.
|checkDeserializeAdvances||Specifies whether the progress of the XmlSerializer is checked. Set the attribute to "true" or "false". The default is "true".|
|useLegacySerializationGeneration||Specifies whether the XmlSerializer uses legacy serialization generation which generates assemblies by writing C# code to a file and then compiling it to an assembly. The default is false.|
|<system.xml.serialization> Element||Contains configuration settings for the XmlSerializer and XmlSchemaImporter classes.|
By default, the XmlSerializer provides an additional layer of security against potential denial of service attacks when deserializing untrusted data. It does so by attempting to detect infinite loops during deserialization. If such a condition is detected, an exception is thrown with the following message: "Internal error: deserialization failed to advance over underlying stream."
Receiving this message does not necessarily indicate that a denial of service attack is in progress. In some rare circumstances, the infinite loop detection mechanism produces a false positive and the exception is thrown for a legitimate incoming message. If you find that in your particular application legitimate messages are being rejected by this extra layer of protection, set checkDeserializeAdvances attribute to "false".
The following code example sets the checkDeserializeAdvances attribute to "false".
<configuration> <system.xml.serialization> <xmlSerializer checkDeserializeAdvances="false" /> </system.xml.serialization> </configuration>
