TypeLoadExceptionHolder

Question

I'm trying to deserialize an object (serialized in .NET 1.1) in .NET 2.0 and one of the child objects is causing a TypeLoadExceptionHolder to be substituted for it in the SerializationInfo during the deserialization process.  This same serialized object will deserialize fine using the same code base built under .NET 1.1.  I cannot find any information on what a TypeLoadExceptionHolder object means or why it is being put in the serialization info slot for the child object.

Any help would be appreciated.

Thanks!

Answer 1

Turned out to be a case sensitivity problem.  The type serialized had a character with a different case than the type that actually exists.  It appears 1.1 doesn't care about this, but 2.0 does.  Can 2.0 be set to 1.1's more lax case sensitivity?

 

Thanks!

This assert is correct both in 1.1 and 2.0

Debug.Assert(null == Type.GetType("System.int32"));
