Nant Script using .Net 2? Why?

I have a very simple setup, a whole solution that builds using .NET 3.5. Runs fine on my machine, and the build server. I have since added a script to my build file, which will create an XML file, listing all the updates for our patcher. This runs fine on my machine, but not at all on the build server.

I have attached the output below, strangely enough, it seems to be compiling the script in .NET 2.0? Which will never work, because LINQ is present in the script.

Anyone have any ideas? Thanks in advance...

BUILD SUCCEEDED

Total time: 0.7 seconds.

I too was having this problem and had to stop using 3.5 features in my NAnt script.

It appears as though NAnt is compiling the code from your block using the v2.0 compiler as NAnt itself was built with the v2.0 compiler.

There is a hack to the NAnt source code suggested here:

http://www.mail-archive.com/nant-users@lists.sourceforge.net/msg11867.html

It says at the top that target framework is 3.5 and the build succeeded, so I think you're okay. It looks like 2.0 is just the version of the framework that generated the NAnt script.
