Why is the After Effects SDK Skeleton Template So Buggy?!

When using the Skeleton template in visual studio 2015 enterprise I start to get so many errors like some of them include the identifiers not being defined even though they clearly are example:

static PF_Err <-error

About (

  PF_InData *in_data, <-error

  PF_OutData *out_data,

  PF_ParamDef *params[],

  PF_LayerDef *output )

{

and also expected deceleration and this decleration has no storage class
