Error: The reference assemblies for .NETFramework,Version=v4.7.1 were not found. To resolve this, install the Developer Pack (SDK/Targeting Pack) for this framework version or retarget your application. You can download .NET Framework Developer Packs at https://aka.ms/msbuild/developerpacks

@JoeRobich you are right . Linux needs mono install along with dotnet core sdk to work out . Thanks for solution.

@PrakTech You make a good point. This isn't a helpful error message when on MacOS or Linux. For these platforms you can install the stable release of Mono (6.8.0 from https://www.mono-project.com/download/stable/#download-lin) to install the .NET 4.7.1 reference assemblies that Unity projects require.

@cartermp Can we update this error or the linked website to include instructions for non-Windows platforms?
