I want to vote for this problem. I am also experiencing this issue. It occurs 
when
the class hierarchy is above 40-50 inherited classes. The stack trace is like 
this:
  ProtoBuf.Property.PropertyFactory.Create[T](MemberInfo member)
  ProtoBuf.Serializer.Build(1)
  ProtoBuf.Serializer.Serialize[T](Stream destination, BooleanValue instance)

I have also seen the exception with this stack trace:
 at ProtoBuf.Property.PropertyFactory.Create[T](MemberInfo member)
 at ProtoBuf.Serializer`1.Build()
 at ProtoBuf.Property.PropertyMessageString`4.OnAfterInit()
 at ProtoBuf.Property.Property`1.InitPrivate(Int32 tag, DataFormat dataFormat,
Boolean isOptional, MemberInfo member, Delegate getValue, Delegate setValue, 
Object
defaultValue)
 at ProtoBuf.Property.Property`1.Init(Int32 tag, DataFormat format, Delegate
getValue, Delegate setValue, Boolean isOptional, Object defaultValue)
 at ProtoBuf.Serializer`1.Build()
 at ProtoBuf.Serializer`1.SerializeChecked(AbstractValue instance,
SerializationContext destination)
 at ProtoBuf.SerializerItemProxy`2.Serialize(DateTimeValue instance,
SerializationContext destination)
 at ProtoBuf.SerializerProxy`1.Serialize(DateTimeValue instance, Stream destination)
 at ProtoBuf.Serializer.Serialize[T](Stream destination, DateTimeValue instance)

The only way to resolve the issue is by excluding members from the inheritance
hierarchy through compiler preprocessor directives.

The error never happens on the desktop framework, only on the compact framework.

I was just wondering if there is a release that has this fixed in it.  I 
believe I am running the latest version and I get this intermittently.  

Thanks for any information you can pass along.

This is a problem with too much generics (internal to protobuf-net). In "v2", 
the entire core has been re-written with this is mind, and it should be far 
happier on CF (and faster, thanks to full pre-generation of dlls).

Note that this is *NOT* yet fully tested, but you are more than welcome to play 
with the "trunk" - note also that the build scripts are not fully tidied at the 
moment.

Marc,

I'm another developer working with adondero above. We're not really wanting to 
move to v2 until it is released. Do you know of any work-arounds to this? We 
only seem to get the problem after some certain number of saved objects has 
been reached (within a single run of the application.) Is there any way to 
"clean up" the Serializer class? Would dynamically loading and unloading the 
protobuf dll make a difference? Any other suggestions?

Thank you,

Steve
