MSBuild for C++ with VS2005

Question

Hi

Does anyone know if it is possible to use the new .NET4 MSBuild to build a C++ project using the VS 2005 compiler and linker?

I'm considering various external build systems for my large C++ project - I need better extension points and compatibility with Continuous Integration tools.
The new MSBuild in .NET4 is an obvious candidate as it now comes with C++ support.
Can I use it with VS 2005, and if so, how do I tell it which compiler to use?
I don't want to use VCBuild as this doesn't have the extension points and flexibility I need.

Thanks in advance,

Ben
