.NET6 target framework and precompiler check for net6.0-windows

by

If we define <TargetFrameworks> in the .csproj like

  <PropertyGroup>
    <TargetFrameworks>netstandard2.0;net6.0;net6.0-windows</TargetFrameworks> 
  </PropertyGroup>

I can define different dependency packages like

  <ItemGroup Condition="'$(TargetFramework)' == 'netstandard2.0'">
    <PackageReference Include="Microsoft.Extensions.DependencyInjection.Abstractions" Version="6.0.0" />
    <PackageReference Include="Microsoft.Extensions.Logging.Abstractions" Version="6.0.0" />    
  </ItemGroup>

 <ItemGroup Condition="'$(TargetFramework)' == 'net6.0'">
     ...
  </ItemGroup>

 <ItemGroup Condition="'$(TargetFramework)' == 'net6.0-windows'">
     ...
  </ItemGroup>

And check in the code with precompiler statements to use different library (version) features

#if (NETSTANDARD2_0)
#endif

#if (NET6_0)
#endift

Works …

But how do I check explicitly for target framework net6.0-windows?
(Unfortunatly) I need differences between Net6.0 and Net6.0-windows.

You may find #if WINDOWS, or #if WINDOWS && NET6_0 work for your needs (maybe consider NET6_0_OR_GREATER, note); otherwise, you can define your own symbol:

<ItemGroup Condition="'$(TargetFramework)' == 'net6.0-windows'">
    <DefineConstants>$(DefineConstants);YOUR_THING</DefineConstants> 
</ItemGroup>

and use #if YOUR_THING
