@jnm2 What does "does not like" mean here? I don't like pineapple on pizza but sometimes you got to eat, ya know? 😄

[kennykerr]

You don't like pineapple on pizza? What kind of monster are you?!

Oh shoot, I'm sorry, I forgot to include the error somehow. It fails the build:

Error CA1418: The platform 'Windows ' is not a known platform name

I think we just need to change the value to "windows8.0" instead of "Windows 8" in supportedOS.rsp.
