NetLah.Abstractions is .NET library of reusable classes for retrieving .NET assembly build time ApplicationInfo, AssemblyInfo.
NetLah.AssemblyInfo.BuildTime.Target is MSBuild target for assembly build-time generation.
This solution come from the idea of Gérald Barré on Meziantou's blog Getting the date of build of a .NET assembly at runtime
<ItemGroup>

4. Use Directory.Build.targets to declare build date time attribute to all projects inside the solution
- Set build date time to projects that already include packageReference
NetLah.AssemblyInfo.BuildTime.Target
<ItemGroup>
<PackageReference Update="NetLah.Abstractions" Version="1.0.0" />
<PackageReference Update="NetLah.AssemblyInfo.BuildTime.Target" Version="1.0.0" PrivateAssets="All" />
</ItemGroup>- Set build date time to all projects
<ItemGroup>
<PackageReference Update="NetLah.Abstractions" Version="1.0.0" />
<PackageReference Include="NetLah.AssemblyInfo.BuildTime.Target" Version="1.0.0" PrivateAssets="All" />
