I am trying to use the XmlSerializer.Deserialize method and I am getting a fileNotFound expection for a tempory dll that should be produced by the serializer.
I have a set of classes generated by XSD.exe from a fairly complex xsd file. I get the error when I try to new the XMLSerializer(typeof(myClass)) constructor.
Does anyone have a suggestion on what I am doing wrong? I'm using framework 1.1 on Win2003 server

I think this is a FAQ

Sometimes you can get a "assembly not found" error at runtime when using the
xml serializer. eg,
Unhandled Exception: System.IO.FileNotFoundException: File or assembly name
zhv7pjut.dll, or one of its dependencies, was not found.
File name: "zhv7pjut.dll"
at System.Reflection.Assembly.nLoad(AssemblyName fileName, String codeBase,
Boolean isStringized, Evidence assemblySecurity, Boolean
throwOnFileNotFound, Assembly locationHint, StackCrawlMark& stackMark)
at System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, Boolean
stringized, Evidence assemblySecurity, StackCrawlMark& stackMark)
at System.Reflection.Assembly.Load(AssemblyName assemblyRef, Evidence
assemblySecurity)
at System.CodeDom.Compiler.CompilerResults.get_CompiledAssembly()

This can happen for various reasons.
- if the classes you are serializing include jagged arrays or other
unhandled data formats
- if you do not have permission to the temp directory (can happen on WS2003
or when you run your app from a new identity)
- if the .NET Framework install is broken
- maybe other reasons
check this tool to help troubleshoot the first problem
http://www.sellsbrothers.com/tools/#XmlSerializerPreCompiler
for the 2nd issue, check the Fusion log - it will indicate pathnames.
Verify that your user is able to read/write to the specified location. Eg,
if an ASP.NET page, then verify that ASPNET (or whoever) is able to write to
c:\windows\temp (or whatever the dir is).

Here's my reason for getting this error: I had a couple of classes that were not public. It's in the documentation, but it bit me unexpectedly, and without Google I would've had a hard time figuring it out. I think the crux of the problem is error mishandling within the XmlSerializer: none of the error messages returned in exceptions point to the real problem.
