Usage of DefineConstant after declaring it in .csproj

Question

_{Thursday, April 26, 2018 6:06 AM}

This question stems from https://social.msdn.microsoft.com/Forums/vstudio/en-US/ca02eb12-eee7-47c4-9096-bd5c10420aed/variable-conditional-compilation-tag-to-update-target-framework?forum=visualstudiogeneral&prof=required

so I have declared  

<PropertyGroup Condition=" '$(TargetFramework)' == 'net471'">
    <DefineConstants>WINDOWS</DefineConstants>
  </PropertyGroup>

in .csproj  to replace NET471 in #if NET471 in code. I want to do the same in .csproj as well.

I have tried in the .csproj to replace

< ItemGroupCondition="'$(TargetFramework)'=='NET471' ">

by

< ItemGroupCondition="'$(DefineConstants)'=='WINDOWS' ">

< ItemGroupCondition="'$(TargetFramework)'=='WINDOWS' ">

< ItemGroupCondition="'$(Configuration)'=='WINDOWS' ">

but it is not working as the NuGet packages are not reference in projects that depend on this project

Can anyone help me on this?

I solved it with

<ItemGroup`` ``Condition``=``"$(DefineConstants.Contains('<DefineConstants>'))"``>

Can anyone verify this?
