我可以将这个旧的csproj迁移到VS2017 csproj吗？

Question

I want to simplify my PCL csproj and I can't seem to find the appropriate TargetFrameworks ..

This is my old csproj:

<PropertyGroup>
    <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>
    <Platform Condition=" '$(Platform)' == '' ">AnyCPU</Platform>
    <ProjectGuid>{D035A2E6-EF3E-4F50-B6D7-396F83FE313F}</ProjectGuid>
    <ProjectTypeGuids>{786C830F-07A1-408B-BD7F-6EE04809D6DB};{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}</ProjectTypeGuids>
    <OutputType>Library</OutputType>
    <RootNamespace>PCL.Acme</RootNamespace>
    <AssemblyName>PCL.Acme</AssemblyName>
    <TargetFrameworkVersion>v4.6</TargetFrameworkVersion>
    <TargetFrameworkProfile>Profile151</TargetFrameworkProfile>
  </PropertyGroup>

The current nuget has a framework folder formatted like portable46-net451%2Bwin81%2Bwpa81 . I cannot target netstandard1.2 because I have a dependency on another PCL...

Any help is appreciated.

Update

This csproj format made it possible to reference my old PCL nuget package. Now I can start migrating the PCL.Acme.Another.Library project.

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFrameworks>netstandard1.2</TargetFrameworks>
    <PackageId>PCL.Acme</PackageId>
    <Authors>Acme</Authors>
    <GeneratePackageOnBuild>true</GeneratePackageOnBuild>
    <PackageTargetFallback>
      $(PackageTargetFallback);portable46-net451+win81+wpa81
    </PackageTargetFallback>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="PCL.Acme.Another.Library" Version="1.0.0" />
  </ItemGroup>
</Project>

Answer 1

I would recreate csproj (start over) with new format it's much easier. This blog post is really helpful https://natemcmaster.com/blog/2017/03/09/vs2015-to-vs2017-upgrade/

Edit: all supported target frameworks https://docs.microsoft.com/en-us/dotnet/standard/frameworks

Edit2:

<PackageTargetFallback>
    $(PackageTargetFallback);portable-net45+win8+wpa81+wp8
</PackageTargetFallback>

Might help as well. More info here https://docs.microsoft.com/en-us/dotnet/core/tools/csproj
