Building NPanday from source (including tests) on 64bit windows fails.
The problem is, that all resources are built with the 64-bit version of the .NET Framework tools. Also then, the nunit-console runs everything (including MSBUILD) in 64 bit.
NPanday itself should allways be built using x86. It should furthermore have strong support for building both 32bit and 64bit apps on 64bit systems.
