Can't build it

[progre]

I tried to build on Visual Studio Community 2017, but can't build with some errors.
Could you tell me how to build it?

Can you try again? You might get different errors but i think these particular errors should be fixed. Make sure you download the submodules too and that all projects load successfully (you have 2 projects that aren't loaded in the image).

OK. Certenly I have forgetten to clone submodule. I retry it as;
git clone git@github.com:Skippeh/Oxide.GettingOverItMP.git --recursive

but my build is still failed with another errors.
It looks like errors about Unity Engine.
