Public methodXamlDuplicateMemberException()Initializes a new instance of the XamlDuplicateMemberException class with a system-supplied message that describes the error.
Public methodXamlDuplicateMemberException(String)Initializes a new instance of the XamlDuplicateMemberException class with a specified message that describes the error.
Protected methodXamlDuplicateMemberException(SerializationInfo, StreamingContext)Initializes a new instance of the XamlDuplicateMemberException class with serialized data.
Public methodXamlDuplicateMemberException(String, Exception)Initializes a new instance of the XamlDuplicateMemberException class with a specified error message and a reference to the inner exception that is the cause of this exception.
Public methodXamlDuplicateMemberException(XamlMember, XamlType)Initializes a new instance of the XamlDuplicateMemberException class with the relevant member and type information to report.

If you handle this exception from a XAML node stream, members might be reported as duplicates in several possible situations. For example, an explicit property element for a XAML content property might be preceded by whitespace that is interpreted as content, if the collection is whitespace significant. Or the XAML writer might be attempting to reset a property that should instead be using a GetObject default value. If you analyze individual nodes in the XAML node stream, you can often determine the source of the problem.

If a XAML object writer provides special handing for duplicate members, it can prevent some duplicate member exceptions if you specify SkipDuplicatePropertyCheck as true in XamlObjectWriterSettings that initialize the XamlObjectWriter.
