Hi, I got stucked in Tut8, after I edited all the codes there are three linking errors and I cannot figure out where is wrong

Here are the build output:

I have replace all the codes to your tutorial 8 changes files but still not work. Here is my current VulkanEngine.zip solution files, hope this could be helpful to find the issue

Try using these linker options: /NODEFAULTLIB:MSVCRT,libucrtd (VS Project properties -> Linker -> Input -> Ignore Specific Default Libraries) Possibly together with: /MDd You could also try clearing the Additional Options field.
