Embedding Resources

Question

I've been trying to embed a couple of .wav sound files in a VS2015 C# WFA. I added the two .wav files to the application resources via the Solution Explorer Add Existing Item. Then I clicked on each of the .wav files in resources and selected Properties/Build Action/Embedded Resource. I expected, when built, the debug or release exe files would contain the wav files (the exe would be standalone.) The doesn't seem to be the case. Am I missing a step or two?
