Question

I\'m getting

Unable to resolve \'NETStandard.Library (>= 1.6.1)\' for \'.NETStandard,Version=v2.0\'.

in VSTS build using Hosted

Answer 1

I have received a similar error after generating a project using dotnet new angular which created a project relying on netcoreapp2.0. Inspection of project properties revealed that version 2.0 was not properly recognized (did not appear in the installed framework list).

Solution was to update Visual Studio 2017, as the minimum version required to support netcoreapp2.0 projects seems to be 15.3.1.
