.NET Core 1.1 app with PCL, unable to build on Team services

Question

I have following projects on solution and this works perfectly fine on my local.

However when I check code in Team service and create build it fails.

mainconsole.csproj

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

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp1.1</TargetFramework>    
    <PackageTargetFallback>portable-net45+win8</PackageTargetFallback>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="Microsoft.NETCore.Portable.Compatibility" Version="1.0.1" />
  </ItemGroup>
  <ItemGroup>
    <ProjectReference Include="..\business\business.csproj" />
    <ProjectReference Include="..\portableextensibility\portableextensibility.csproj" />
    <ProjectReference Include="..\portablelibrary\portablelibrary.csproj" />
  </ItemGroup>
</Project>

Build tasks:

command line - tool dotnet, argument - restore
command line - tool dotnet, argument - build

Build fails:

does dotnet build work on your local machine? I believe it doesn't. — Martin Ullrich
It works. as I think? I copied portable from C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\Microsoft\Portable to C:\Program Files\dotnet\sdk\1.0.4\Microsoft\Portable — Avi Kenjale
So in this case, msbuild (commandline) and dotnet build both works. — Avi Kenjale
you'd have to script that copy for the build servers as well.. msbuild should work automatically on the build servers without copying — Martin Ullrich

Since the solution contains PCL libraries which currently cannot be built using the dotnet cli, the project has to be built through msbuild instead of the dotnet based commands.
