Read a nuget package library version in the target assembly when installed

Question

How to find the installing package library version in the target assembly?

Assume that:

We have NugetLib and ConsumerApp (which will install NugetLib).

I am using .targets file in NugetLib named the same, and it will run on the target when installed.

Inside NugetLib.targets file:

  <Target Name="Main" AfterTargets="Build">
    <Message Text="$(NugetLibVersion)" Importance="high" />
  </Target>

Currently I don't have the correct value of NugetLibVersion, and it needs to be set somehow.

Using $(PackageVersion)" will not help, cause it doesn't read and provide NugetLib version, it will provide ConsumerApp version (the target assembly, which will always be 1.0.0.0).

If you know a way achieving this including setting some special properties, or even by using text files, or any other own or tricky methods are all welcome and appreciated.

If your project is new sdk style format, you can just add this custom target to get the nuget version:

  <Target Name="PrintPackageReferences" AfterTargets="Build">
    
    <Message Text="Dependencies:%0A  @(PackageReference->'%(Identity), Version: %(Version)', '%0A    ')" Importance="High" />

    <CreateProperty Condition="'%(PackageReference.Identity)'=='NugetLib'" Value="%(PackageReference.Version)">
     <Output TaskParameter="Value" PropertyName="NugetLibVersion" />
    </CreateProperty>

    <Message Importance="high" Text="$(NugetLibVersion)"></Message>
    
    </Target>
