C API Core Samples

The build procedures for the C API SDK samples on all supported platforms are described in the "Getting Started" section. Note that the native\core directory contains some C++ sample sub-directories which can be viewed here. By default, all sample executables are built in the target/bin directory, so after building the sample(s) it is convenient to cd to target/bin to run the sample or run it in the development system debugger.
