[UWP] [IL2CPP] Build issues (in VS2017)

Hey folks,

I am having an issue with building a project for UWP application. I managed to build it successfully in Unity, but when I try to build the solution in VS I get these errors:
1>9142A4402ED4365A603F81F84CE5000E.obj : error LNK2019: unresolved external symbol dlopen referenced in function Mono_dlopen_m0A57E032EF60E81CAEAA00AEF1F8E4AFBCB7D991
1>9142A4402ED4365A603F81F84CE5000E.obj : error LNK2019: unresolved external symbol dlsym referenced in function Mono_dlsym_mEADD0CFB8DDC1C7F3DF7E8D6AA93B559376B551F

Does anyone know what this means? This is my first time making a UWP app so some guidance would be extremely helpful.

Thanks in advance.

Here's my full output:
