+Summary: [2.0] CompareInfo binary serialization not compatible with MS
+
+MS introduced CompareInfo.Name in .NET 2.0, which results in an additional
+field that is serialized (m_name).
+
+This field is not available in Mono. We do appear to have an icu_name
+field, but I'm not sure if the semantics of these fields match.
+
+I also noticed that MS allows deserialization of a .NET 1.1 CompareInfo
+blob on .NET 2.0, even though m_name is not serialized in .NET 1.1. MS
+might be using its newly introduced Version Tolereant Serialization
+mechanism here.
+
+I've added deserialization unit tests for CaseInsensitiveComparer which
+fails as a result of this issue.
+
+Attempting to deserialize an MS.NET 2.0 CompareInfo blob results in the
+following exception:
+
+System.Runtime.Serialization.SerializationException : Field "m_name" not
+found in class System.Globalization.CompareInfo
