A .NET Core website won't build on OS X - “Assets file '…/obj/project.assets.json' not found.”

I'm trying to build a .NET Core application that I created on Visual Studio 2017 on Windows on Visual Studio 2017 for Mac.

I've run a 'dotnet restore' which seems to complete correctly. However, when I build, I get the following:

/usr/local/share/dotnet/sdk/1.0.1/Sdks/Microsoft.NET.Sdk/build/Microsoft.PackageDependencyResolution.targets(154,5): error : Assets file '.../obj/project.assets.json' not found. Run a NuGet package restore to generate this file. [.../TME.PatternLibrary.csproj]

And several error CS0246: The type or namespace name 'System' could not be found (are you missing a using directive or an assembly reference?)

How can I build the .NET Core project on Mac OS X?

Please make sure you have proper .net core version on OSX (even beta). VS 2017 uses new project type where json files are replaced with xprojfiles. – pwas
I have the following - Microsoft .NET Core Shared Framework Host Version : 1.1.0 Build : 928f77c4bc3f49d892459992fb6e1d5542cb5e86 – Jamie Gilbert
Run dotnet.exe --version on OSX. – pwas
dotnet --version = 1.0.1 – Jamie Gilbert
It looks like your mac isn't registering you have .Net core 1.1.0 installed if your output from dotnet --version is 1.0.1. This will most likely be the issue. have you downloaded and manually installed .net core 1.1.0 ? microsoft.com/net/core#macos – BigTallJosh

It looks like your Mac isn't registering that you have .NET Core 1.1.0 installed if your output from dotnet --version is 1.0.1. This will most likely be the issue. If you download and manually install .NET Core 1.1.0, this should solve your problem.

You can download it from here.
