    <p>/usr/local/share/dotnet/sdk/1.0.4/Microsoft.Common.CurrentVersion.targets(1111,5):
    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. [/Users/swayans
