Question

I have seen some posts that mention the xmlserializer being called at runtime in .Net.

I have a sharepoint web-part that calls a webservice to retrieve data, and then is supposed to display that data on the web-part. But I get this error:
System.Runtime.InteropServices.ExternalException: Cannot execute a program. The command being executed was “C:\Windows\Microsoft.NET\Framework64\v2.0.50727\csc.exe” /noconfig /fullpaths @”C:\Users\my_deploy_spFarm_user\AppData\Local\Temp\OICE_356C17F3-2ED2-423C-8BBE-CA5C05740FD7.0\eelwfhnn.cmdline

Now the posts I have read here, state that the problem is that the compiler is trying to to create an XML serialization assembly on the fly, but does not have privilege to do so.

I have seen some suggestions to use the post-build events to create this XML Serialization Assembly at Compile-time. However I am not sure of how to do that, and also I am not sure if this assemply would get included in the .wsp package?

I’d take a good look at whether you really want the full, automatically generated serializer, or whether you just want to emit/parse some relatively straightforward XML – if the latter, you’ll solve this problem by not using stuff that needs generated code, i.e. use the XmlReader/XmlWriter directly.
