[FiveM] dynamic types not working after loading this library

[Sander0542]

After this library has been loaded by the FiveM client, the dynamic type doesn't work anymore.

I ran the same code, but without LemonUI. That worked without any exceptions. Why could this happen?

Hm... weird.

What specific LemonUI features are you using?

[Sander0542]

It happens when I load the library and not even use any of the features. Just adding the NuGet packages triggers the error.

When I add all the .cs files to the project and compile it there it works.

[justalemon]

It happens when I load the library and not even use any of the features

Including the fxmanifest.lua reference? It needs to be added as a client script.

[Sander0542]

I tried with and without the reference in the client_scripts property in the fxmanifest.lua

[Sander0542]

This code sample doesn't work while using LemonUI.FiveM

public class ClientMain : BaseScript
{
    public ClientMain()
    {
        Tick += PlayerJoinedTick;
    }

    private async Task PlayerJoinedTick()
    {
        if (API.NetworkIsPlayerActive(API.PlayerId()))
        {
            Exports["spawnmanager"].setAutoSpawn(false);

            Tick -= PlayerJoinedTick;
        }
    }
}

[Sander0542]

I did some testing myself and was able to build a NuGet package which works.

This commit fixes the error (I only tested with FiveM) https://github.com/LemonUIbyLemon/LemonUI/commit/292e1f303b479661f59e7ab68b2d5bc2aaba518b

[justalemon]

Ill take a deeper look tomorrow Sunday.

[TomStilson]

I'm gettting the same problem and I think its related to Exports in CitizenFX.Core. For some reason, if LemonUI is loaded, whenever you use Exports, the exception System.TypeLoadException: Could not resolve type with token 0100000e will be thrown.

[justalemon]

Pinpointed the problem back to version 1.3.0, so this was caused by something between 1.2.0 and 1.3.0.

Ill try to see what I can do, but I would expect this to be fixed in the FiveM codebase instead of a LemonUI patch, as is not a LemonUI bug.

[justalemon]

[Sander0542]

When I updated the build system in my branch, I got it to work with the latest FiveM version. I am not very experienced with the C# compiler, but maybe you could take a look at my branch and see what could have fixed it.

One change that stands out is the removal of the .net suffix in assembly name of the FiveM csproj

<AssemblyName>$(AssemblyName).net</AssemblyName>

[justalemon]

That could work, yes. But this appears to be a FiveM bug that needs to be diagnosed and fixed upstream.

By the way, have you tried to just rename LemonUI.FiveM.net.dll to LemonUI.FiveM.dll?

[Sander0542]

By the way, have you tried to just rename LemonUI.FiveM.net.dll to LemonUI.FiveM.dll?

No, I have not tested that

[justalemon]

Interesting...

[justalemon]

Managed to trigger the same FiveM crash again:

[justalemon]

Ill end up using the solution suggested by @Sander0542

Looks like FiveM doesn't knows how to deal with the libraries set as client_script(s), so you will always see one of this:

• System.TypeLoadException: Could not resolve type with token 0100000e
• mono-2.0-sgen.dll!memcpy (0x180) crash

The behavior changes depending on the LemonUI version. Recent versions (1.3-master) show the exception, while old versions (alpha-1.2) show the crash.

Not gonna lie, I have been trying to fix this shit for months, fucking burnout got me every single time.

As it turns out, it was FiveM all along.

@Sander0542 would you be kind to send the Pull Request? So you get the credit for the commit :)

[Sander0542]

I created a pull request with the required changes https://github.com/LemonUIbyLemon/LemonUI/pull/99

If you want me to implement GitVersion, so you don't have to manually change the version for every release, then let me know and I'll create another PR with that part
