This one works only with '$(OS)' != 'Windows_NT'.. Why doesnt this build on windows?

I'd be interested to know why you're trying to compile for a different target framework depending on the operating system. I wouldn't normally recommend this.

Can you provide more information on how this is failing? If you can provide a binlog that would help.

Finally, if you really do want to set the target framework based on the OS, I would suggest trying to do it with an entirely SDK-style project, like this:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <TargetFramework Condition=" '$(OS)' == 'Windows_NT' ">net461</TargetFramework>
  </PropertyGroup>

</Project>

There is a scenario where we need to run the existing project(windows) on Linux. so i was trying this approach.
