Do I still need MSBuild.Sdk.Extras with .net6?

[datoml]

Hello, I hope it is ok to ask in the issue section but I wonder If I still need MSBuild.Sdk.Extras with .net6 coming out pretty soon.

Based on the new MAUI examples I tried to achieve the same with pure SDK style project. So what I did was creating a sample project and added the following lines to it.

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

    <PropertyGroup>
        <TargetFrameworks>net6.0-windows;net6.0-ios;net6.0-android;net6.0-maccatalyst</TargetFrameworks>
        <Nullable>enable</Nullable>
    </PropertyGroup>

    <ItemGroup>
        <Compile Remove="Platforms\**\*.*" />
        <None Include="Platforms\**\*.*" />
    </ItemGroup>

    <ItemGroup Condition="$(TargetFramework.Contains('-windows'))">
        <PackageReference Include="System.Management" Version="5.0.0" />
        <PackageReference Include="System.IO.Ports" Version="6.0.0-preview.2.21154.6" />
        <Compile Include="Platforms\Windows\**\*.cs" />
    </ItemGroup>

    <ItemGroup Condition="$(TargetFramework.Contains('-android'))">
        <Compile Include="Platforms\Android\**\*.cs" />
    </ItemGroup>

</Project>

This works exactly like I hoped but when I reference the project to a console application for instance I am not able to call the methods. Is there something crucial missing here or is it still not supported? Thanks!

What is the TFM of your console application?

The TFM is set to net6.0-windows. I made a Multi-Target library and referenced it to a net6.0 library that is also referenced in my console application. So I think the issue was on my side that I used it wrong. I had to reference the Multi-Target library in my net6.0-windows app and pass it with an interface to the .net6-0.

This is the correct and only way because the net6-0 library doesn't know the OS. Is this assumption correct?

It was 100% on my side. I mixed up some things in my head. 😅

If someone comes across the same "problem", this is the solution to it.

To give you a little bit of context. The idea is to create a multi-target library that is able to work with the .net6.0 TFM. What I do here is to separate android, linux and windows. Android is easy because there is a TFM for it. For linux and windows I use a separate configuration. Default will be windows.

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

  <PropertyGroup>
    <TargetFrameworks>net6.0;net6.0-android</TargetFrameworks>
    <LangVersion>Preview</LangVersion>
  </PropertyGroup>

  <ItemGroup>
    <Compile Remove="Platforms\**\*.*" />
    <None Include="Platforms\**\*.*" />
  </ItemGroup>

  <ItemGroup Condition="$(TargetFramework.Contains('-android'))">
    <Compile Include="Platforms\Android\**\*.cs" />
  </ItemGroup>

  <ItemGroup Condition="!$(TargetFramework.Contains('-android')) and ($(Configuration) == 'Debug' or $(Configuration) == 'Release')">
    <Compile Include="Platforms\Windows\**\*.cs" />
  </ItemGroup>

  <ItemGroup Condition="!$(TargetFramework.Contains('-android')) and $(Configuration.Contains('-Linux'))">
    <Compile Include="Platforms\Linux\**\*.cs" />
  </ItemGroup>

</Project>
