How to bootstrap .NET 3.5 SP1 with msbuild? following found instructions doesn't work

Question

I'm trying to use msbuild GenerateBootstrapper task to distribute a .net application with the framework, without the need of internet connection to install it.

I've found many posts that all lead to the same instructions in here:

Enable Samesite for the .NET Framework 3.5 SP1 bootstrapper

After following the instructions, I still cannot generate the bootstrapper. The more obvious issue I can see is that extracting the files from dotNetFx35.exe does not extract the same list of files and folders than shown on the readme file (for example TOOLS folders are not there).

What am I doing wrong? Am I following old instructions?

msbuild errors are as follows:

Any help would be really appreciated!

I've resolved the issue. The link provided by Microsoft's documentation to download the full .net framework 3.5 SP1 is not correct. The package from .NET Framework 3.5 SP1 full install package does have the expected files inside.
