FIX: You receive an error message when you try to transfer data between an application that runs on the .NET Framework 2.0 and an application that runs on the .NET Framework 1.1


Consider the following scenario. You have an application that runs on the Microsoft .NET Framework 2.0 and an application that runs on the Microsoft .NET Framework 1.1. You try to use Microsoft .NET Framework remoting or binary serialization to transfer data between the applications. In this scenario, you receive an error message that is similar to one of the following error messages:
Error message 1
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object
Error message 2
Unhandled Exception: System.ArgumentOutOfRangeException: Ticks must be between DateTime.MinValue.Ticks and DateTime.MaxValue.Ticks. Parameter name: ticks
Error message 3
System.Runtime.Serialization.SerializationException: Possible Version mismatch. Type MyNamespace.MyInnerClassV2 has 2 members, number of members deserialized is 1
Error message 4
System.Runtime.Serialization.SerializationException: Wrong number of Members. Object MyNamespace.MyInnerClassV2 has 2 members, number of members deserialized is 1
Error message 5
System.Runtime.Serialization.SerializationException: Member name 'MyNamespace.MyInnerClassV1 v2Field' not found
Error message 6
System.IndexOutOfRangeException : Index was outside the bounds of the array
This problem occurs when all the following conditions are true:
  • Both applications use either Microsoft .NET Framework remoting or runtime serialization.
  • Data transfer flows from the .NET Framework 2.0 to the .NET Framework 1.1.

    This data transfer may occur in any one of the following scenarios:
    • A .NET Framework 2.0 server returns data to a .NET Framework 1.1 client.
    • A .NET Framework 2.0 client sends data to invoke a .NET Framework 1.1 service.
    • Data is serialized on the .NET Framework 2.0, and data is deserialized on the .NET Framework 1.1.
