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).

This worked for me in VS2017:

Start with .net core web project template.

Edit *.csproj so it looks like this:

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

  <PropertyGroup>
    <TargetFramework>net472</TargetFramework>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore" Version="2.1.3" />
    <PackageReference Include="Microsoft.AspNetCore.CookiePolicy" Version="2.1.2" />
    <PackageReference Include="Microsoft.AspNetCore.Http.Abstractions" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.HttpsPolicy" Version="2.1.1" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc" Version="2.1.2" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc.Core" Version="2.1.2" />
    <PackageReference Include="Microsoft.AspNetCore.Mvc.RazorPages" Version="2.1.2" />
    <PackageReference Include="Microsoft.AspNetCore.StaticFiles" Version="2.1.1" />
  </ItemGroup>

</Project>

Save and close.

Try running project.

The PackReferences is just the NuGet files, and you can add them through the GUI if the versions are different from mine above.
