Did you get all the nuget packages? The package BytecodeApi.Penetration seems to be missing. Normall,y VS should retrieve all nuget packages automatically... Can you do some troubleshooting there and see why the package is not downloaded?

One side note before you stumble upon it later: From version 1.8 on, you need to do a rebuild solution, and run both publish profiles of TestConsole. TestConsole requires a publish, not just a build.

using Visual STudio Installer to install the VS 2025

I am not sure if BytecodeApi.Penetration has been included

[bytecode77]

I mean the nuget packages, not the modules of Visual Studio. Not sure if this is a bug in VS 2026, or a hickup of the package manager after VS 2022 -> 2026 upgrade, but it's not supposed to fail. Can you try to restore/reinstall the nuget packages and/or clear nuget cache? It's rare that nugets fail like this, but there shouldn't be any build issues, so it's worth a try.

wouldn't work by reinstall or repair

In issue #144 someone had build issues with the VS 2026 solution, too. There must be something wrong, either with the solution or the brand new VS 2026. Unfortunately, doing trouble shooting remotely like this isn't going to work - you'll probably have to try out a dozen of things before you know what caused this, I can't help with that from over here... But I really do want to know what's causing build issues, as I don't want to publish a non-compilable project here. Can you try to do some ChatGPT trouble shooting and let me know what caused the build error when you found out?

[wineggdrop]

can't make it work.
re-install the VS 2026 can't fix that issue,so I use my old pc to clean install the VS 2026 by VS intaller,and using it to open the V 1.8.1 R77 project,it will show me what component needed to install,however,it results the same error.

old pc OS : Windows 10 IoT 2021 LTSC
persional pc OS: Windows 10 LTSC 2019

I just installed VS 2026 in a VM and tried to compile the solution. First of all, VS deleted the file under Stager\Properties\Resources.Designer.cs, no idea why that happened.

Next, VS shows this message:

This message is probably becauase the Stager project requires .NET 3.5, so I installed it. The framework must be 3.5:

Changing it to 4.8 made compilation work, but the actual rootkit was no longer working. Looks a lot like .NET 3.5 is missing, mixed in with VS bugs (a project file gets deleted!?).

Yes, you do need .net 9, too.

Any luck with that? Can you pinpoint the issue?

[wineggdrop]

no,I did install all the requirement including .net 4.8 and etc until VS deesn't show more to install,and still getting that error,no sure
if I use windows 10 LTSC or IoT other than windows 11
