JonnyG: Does this link help you?

(Sorry, I’m personally not doing much Nant these days but I seem to recall jumping through an extra hoop if you want to use Nant for .NET 4.0 apps. If this link doesn’t help you, search around more on that topic. I don’t believe this error has anything to do with 64-bit stuff.

I’m getting a strange error on my Win7+.Net4 workstation when testing the above nant code. Any assistance would be extremely helpful!

NAnt 0.90 (Build 0.90.3780.0; release; 5/8/2010)

Buildfile: file:///c:/testproject/default.build
Target framework: Microsoft .NET Framework 2.0
Target(s) specified: check.os.32or64bit

[property] Target framework changed to “Microsoft .NET Framework 4.0″.
[cd] Current directory changed to “c:\testproject”.

check.os.32or64bit:

You are probably using a newer build of NAnt (0.91 Alpha 1/2) instead of 0.85. Just reference the System.dll like so:
