c++ - Cannot build hl2 source solution

Question

I successfully made a mod of half life 2, but when I try to build the solution it fails with roughly 90 errors. These problems can't be related to the mod, as I have not added anything yet, I created a hl2 mod using source 2006 and immediately tried to build when I received this: (P.S. I'm using windows 10 and visual studio 2013)
