XmlSerializer and TypeLoadException

[Magnus Lindhe]

Hello,

I'm trying to deserialize an XML document into a objects with the
XmlSerializer which works fine in my NUnit test suit but fails with a
TypeLoadException in the server. The difference between the server and
the NUnit test suit is that the server will load the assembly
(Flux.Grease.Services.dll) as a plugin in its own AppDomain whereas
the NUnit test suit reference the assembly in the usual way.

The code that performs the deserialization reside in the
Flux.Grease.Services assembly and looks like this:

XmlSerializer serializer = new XmlSerializer(typeof(CitectExport));
citectExport = (CitectExport) serializer.Deserialize(reader);

The exception I receive is a InvalidOperationException and its
InnerException looks like this:

--------- Exception Data ---------
Message: Could not load type Flux.Grease.Services.Citect.CitectExport
from assembly Flux.Grease.Services, Version=1.0.1412.25430,
Culture=neutral, PublicKeyToken=null.
Exception Type: System.TypeLoadException
Source: u9n6cgik
StrackTrace: at Microsoft.Xml.Serialization.GeneratedAssembly.XmlS erializationReader1.Read33_CitectExport()
TargetSite: System.Object Read33_CitectExport()

Why can't the class Flux.Grease.Services.Citect.CitectExport be loaded
from the XmlSerializer generated assembly? How can I resolve this?

Any help appreciated, thanks.
