Answer 1

In my case, I had two versions of Visual Studio installed (15.7 and 15.6). 15.7 didn't have the web workloads installed, though .net core 2.1 RC1 was already installed. I installed the asp.net workload into VS2017, and then repaired my .net core install for good measure. Definitely something in this process swapped my c:\program files(x86)\dotnet and c"\program files\dotnet in this path and Visual Studio (15.7) wouldn't open my web project.

I simply edited the System Environment variables, moved the x86 folder down one and voila - reopened Visual Studio and it now loaded my project.
