Hello, this project is awesome and is exactly what android needs!
We are currently porting the bitsquid (http://www.bitsquid.se) game engine to android, and chose to go with http://code.google.com/p/vs-android/ for building all native code. With this, we don’t have to use the (IMHO) unstable ndk makefiles/cygwin and build time are lowered by a factor 3-6x. The development experience/effectivity would be immensely improved if we also had support for visual studio integrated debugging. I’m also confident that NVIDIA would be very interested to see such a solution delivered to all of their android developers.
The problem with vs-android is that Google may change some NDK internals one day making the hardcoded settings in vs-android unusable (or even worse, producing some hidden hard-to-pinpoint bugs). If you’re interested, I can instruct you how to configure VisualGDB to debug your vs-android projects.
