Xml Serialization Intermittent Failure

[Robert]

We have an ASP.NET site that performs a lot of xml serialization. The serialization occurs in the lbolibrary dll. Occasionally we get an .out file produced in the Winnt\temp folder that contains the following:

C:\WINNT\system32> "c:\winnt\microsoft.net\framework\v1.1.4322\csc.ex e" /t:library /utf8output /R:"c:\winnt\assembly\gac\system.xml\1.0.5000.0__b7 7a5c561934e089\system.xml.dll" /R:"c:\winnt\assembly\gac\lbolibrary\1.0.0.0__30b57 061a1ea7c52\lbolibrary.dll" /R:"c:\winnt\microsoft.net\framework\v1.1.4322\msco rlib.dll" /out:"C:\WINNT\TEMP\yxouf9ik.dll" /debug- /optimize+ /w:1 "C:\WINNT\TEMP\yxouf9ik.0.cs

Can you explain this problem? Our users get a filenotfound exception. This occurs about once or twice every day

Thank

Robert,

The .out file is part of the normal workings of the XmlSerializer. Take a
look at my recent article on MSDN [0] to see if that helps finding the
source of the problem.

The questions I have though after reading your problem description is: Are
you instantiating XmlSerializer instances over and over or can you keep them
around? If you don't keep them around, which constructor overload are you
instantiating the instances with?

Hi Christop

I realize that the generation of the .out file is normal
My understanding is that this disappears once the assembly is compiled
However I have not seen following error in an .out file before:

I am using the XmlSerializer(Type) constructor

Do you have any idea what could cause this

Thanks

Robert,

That error is somewhat confusing coming out of the compilation step. Have
you looked at the file that's causing the error?

Does the Type your serializing carry any special security attributes?

Christop

This error is intermittent, so the file is being compiled sometimes..
There are no special attributes on it

I am struggling trying to diagnose this one

Thanks for your help.

Robert,

what are you doing to capture the error? Are you running your application
with the diagnostics swtich set so all files created by the XmlSerializer
stay in the temp dir so you can take a look at the line that's causing the
problem?

Are you always serializing the same types or how many different types are
you trying to serialize?
