Build from source failed

[schn4v1d]

Got this when trying to build from source (newest release 2018.1 or something)

I entered "msbuild Ultraviolet.proj"

Build FAILED.

I'm guessing you need to install .NET Framework SDK 4.7.1, which includes the reference assemblies for .NET Standard 2.0 libraries. The new expressions compiler requires it.

This might be something I should look at improving in the immediate future.

Ah, yes, I see the problem -- if you don't have the SDK installed, there's a bit of code that's supposed to use NuGet to download the necessary assemblies, but that seems not to be working correctly. I'll see if I can get that fixed here shortly.

[tlgkccampbell]

OK, I've just committed a change to the develop branch which should allow the compiler to work even on systems which don't have the 4.7.1 SDK installed (though I would still recommend that you install it). Let me know if you still have issues.

I got it to work now, thanks for your help!
