Serialization breaks in .NET 4.5

Question

We have a serialization issue which only happens in .NET 4.5 - same code works fine in .NET 4. we\'re trying to serialize an inherited type with a few fields, both base and

Answer 1

I looked at your types more closely, and the problem is likely caused by a conflict between:

public virtual object @Value
{
}

on the Base and:

private new object Value
{
}

on the Derived class. Here are two things I would try:

1. Try making the "new object Value" public. There might be a member access problem.
2. Try renaming the Base's "@Value" to something like "BaseValue" or some other appropriate name. There might be a problem with your use of the '@' sign.
