Removing Stubborn Dependencies in Visual Studio

Hi! So I'm getting a laundry list of errors whenever I try to build in Visual Studio. An example is: 10>CSC : error CS0006: Metadata file 'C:\*ProjectName*\*ProjectName*\Temp\UnityVS_bin\Debug\Unity.2D.PixelPerfect.dll' could not be found This error happens for all of the current packages I have installed for Unity. My current project has dependencies to all of these packages (set up by Unity, I didn't do that explicitly) and when I attempt to remove the dependencies, Visual Studio says the dependency was created by the project system and cannot be removed. I'm pretty new to this sort of thing, so any help moving forward would be appreciated, thanks!
