Can't build the code for .NET 4.5 on Linux (mono)

See original GitHub issue

Steps to reproduce

I’ve created a project with two target frameworks: net45 and netstandard1.6

<Project ToolsVersion="15.0" Sdk="Microsoft.NET.Sdk">

    <Compile Include="**\*.cs" />
    <EmbeddedResource Include="**\*.resx" />

  <ItemGroup Condition=" '$(TargetFramework)' == 'net45' ">
    <Reference Include="System" />
    <Reference Include="Microsoft.CSharp" />

  <ItemGroup Condition=" '$(TargetFramework)' == 'netstandard1.6' ">
    <PackageReference Include="NETStandard.Library" Version="1.6.1" />

Expected behavior

I can build the project for both targets

Actual behavior

It fails on building for net45 with this error

/usr/share/dotnet/sdk/1.0.0-preview4-004233/Microsoft.Common.CurrentVersion.targets(1107,5): error MSB3644: The reference assemblies for framework ".NETFramework,Version=v4.5" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend. [/home/ravenger/TestMonoProject/TestMonoProject.csproj]

Dnx and Dotnet CLI preview 2 supports Mono out-of-the box. I think this version of CLI should support it as well

As @livarcocc mentioned, the right place for this issue is the SDK repo and potentially the MSBuild repo. The dotnet/sdk#335 issue already tracks this and @borgdylan mentioned on that issue that he opened another one on MSBuild. With all of that, I will close this issue and let the discussion continue on the SDK issue.

if you feel this is an error, please reopen. Thanks!
