Summary: The process cannot access the tmp file

Initial Comment:
when I start NAnt I see error:
"BUILD FAILED

Failed to initialize the 'Microsoft .NET Framework 2.0' (net-2.0) target framework.

    The process cannot access the file 'C:\Documents and Settings\User\Local Settings\Temp\tmp2E.tmp' because it is bein
g used by another process."

It occures only when the one Kaspersky Internet Security 2009 module is started ("Proactive Defense").

For details see NAnt output with -debug in attachment

Message:
The problem was that we were creating a filestream with write fileshare;
this denied read access to other processes (such as an anti-virus).

But writing the project XML to file was indeed not necessary, so I removed
this.
