Convert .Net Core to .Net Framework

I have loaded core project to the VS 2017 RC Community and open *.csproj in text editor.

Just delete teg

<RuntimeFrameworkVersion>

and replace

<TargetFramework>netcoreapp1.1</TargetFramework>

to

<TargetFrameworkVersion>v4.6.1</TargetFrameworkVersion>

And after all in project properties set to any another framework and reset back (VS reload and repair *.csproj file).
