I am attempting to create a very simple Microsoft DSS program in which I subscribe to the events generated by the example Kinect DSS that implements speech recognition with the array microphone. However, I get the error seen below at runtime.
I've referenced the proxy .dll that exposes the interface, but a problem occurs at runtime.
I've tried setting my build target platform to x86, but that did not seem to fix the problem. Is there a way that I can verify that my project is being built to target x86?

It turns out that what one has to do is start the program using dsshost32 rather than the default post-build dssproxy that is run by the template Visual Studio .sln for DSS nodes. This runs the DSS node on a 32-bit CLR, and the Kinect libraries work fine.
It then seems as though a tedious series of actions is necessary in order to get code changes from Visual Studio to show up when using dsshost32:
