Not sure if I did anything wrong, but running winetricks -q dotnet35sp1 with wine-git with your patch in a 64bit prefix yields
"002e:err:module:DelayLoadFailureHook failed to delay load imagehlp.dll.BindImageEx wine: Call from 0x7b43e213 to unimplemented function imagehlp.dll.BindImageEx, aborting"
for me.
Looks like the patch didn't apply, or maybe you forgot to regenerate the Makefile?
