Building with .net framework 4.8

[Leon-Cantin]

Hello, I am trying to decompile some files for Endwar which is based on UE3 and so I tried to open the .upk but I am getting some errors so I tried building the projet and debugging locally with vscode to see if I could figure out what is going on and maybe add support for the game if I figure it out.
I tried building with vscode at first but it seems to use dotnet cli which is not the way the .net sdk framework 4.8 works. It uses MSBuild (thanks MS for making this so confusing)
So I finally figured that running with the command
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\msbuild "E:\Development\UDK\UE-Explorer\UE Explorer.sln"
would allow to build with your specific .net version but I am getting an error from MSBuild that all of the .csproj are not supported by MSBuild. Does this ring any bell?

I am also getting errors like:
E:\Development\UDK\UE-Explorer\UELib\src\Eliot.UELib.csproj(1,1): error MSB4041: L'espace de noms XML par défaut du projet doit être l'espace de noms XML MSBuild. Si le projet a été créé au format MSBuild 2003, ajoutez xmlns="http://schemas.microsoft.com/developer/msbuild/2003" à l'élément <Project>. S'il a été créé dans des formats anciens comme 1.0 ou 1.2, convertissez-le a u format MSBuild 2003.
which seem linked to the issue. Saying something like the default XML project namespace must be the MSBuild namespace. I tried adding the xml element above but I am getting more errors.

Maybe you ran into such an issue before?

Thanks

That's unfortunate :(

I gave it a try myself, I ran into a few issues but they were easy to fix, however I couldn't reproduce your build error.

Have you tried this command: dotnet build UEExplorer.csproj /property:GenerateFullPaths=true /consoleloggerparameters:NoSummary, I used the C# Dev Kit extension.

Some compiled .exes are just wonky with Ghidra :/ Even for me this one is missing the usual strings like "Bad Expr"

btw: I added support (mostly) for EndWar just now, see https://github.com/EliotVU/Unreal-Library/commits/feature/Feature-endwar/

Wow, thanks a lot for this, I didn't expect you to go this far. This should help us in our endeavour. Can I ask you where you got your EndWar exe?

[Leon-Cantin]

I got the lib on the endwar feature branch but I am still getting the same error after recompiling. Is there anything I need to activate?

[Leon-Cantin]

I installed Ghidra on a Windows 10 VM and a Kali VM then installed Ghidra on both and decompiled endwar.exe. Every single one gave me the same result. I wonder if it's something special with the steam version ...

[Leon-Cantin]

I decided to buy the Ubisoft Connect version and for some reason that one is different from the steam version and from your version with MD5:00632513640A4EE2F45A16DD94E89203.

BUT it does decompile nicely and I found the functions you mentionned at the start. I can now follow along if there's anything left to do.
