+Summary: [2.0] deserialization interop issue with missing members
+
+Description of Problem:
+Mono always throw a SerializationException if a member of a structure is
+missing. MS stopped doing that in 2.0.
+
+Steps to reproduce the problem:
+1. Compile ser with HAS_STRING.
+
+C:\Temp>csc ser.cs -d:HAS_STRING
+Microsoft (R) Visual C# 2005 Compiler version 8.00.50727.42
+for Microsoft (R) Windows (R) 2005 Framework version 2.0.50727
+Copyright (C) Microsoft Corporation 2001-2005. All rights reserved.
+
+2. Execute ser.exe. The output will have a serialized structure with an
+int32 and a string.
+
+C:\Temp>ser
+Serializing x 2147483647 as a System.Int32
+
+3. Recompile ser.cs without HAS_STRING
+
+C:\Temp>csc ser.cs
+Microsoft (R) Visual C# 2005 Compiler version 8.00.50727.42
+for Microsoft (R) Windows (R) 2005 Framework version 2.0.50727
+Copyright (C) Microsoft Corporation 2001-2005. All rights reserved.
+
+4. Execute ser.exe with the previous serialized output.
+C:\Temp>ser System.Int32.serialized
+x 2147483647
+
+Actual Results:
+Works on MS 2.0.
+Fails on MS 1.1.
+Fails on Mono - both 1.1 and 2.0 profile.
+
+Expected Results:
+Should work on Mono 2.0 profile.
+
+How often does this happen? 
+Always (Mono 2.0 profile)
+
+Additional Information:
+
+If executed with MS 1.1 the result of the deserialization (step 4) is:
+
+Unhandled Exception: System.Runtime.Serialization.SerializationException:
+Possib
+le Version mismatch. Type X has 1 members, number of members deserialized is 2.
