IL2CPP builds don't work?

[meds]

Only happens with IL2CPP, Mono is fine.

My build settings:

I get the following error when building an apk:

Hello!
Are you downloading the plugin from nuget? Otherwise, you have to remove the RSG.Promise dll for .NET 305 (legacy code) because you only need the .NET Standard version.

Please, let me know and thanks for use this plugin

[jdnichollsc]

What do you think about this issue my friend? Real-Serious-Games/C-Sharp-Promise#84

[meds]

As per your suggestion I deleted RSG.Promise_net35.dll, unfortunately that didn't seem to solve the issue or at least creates another issue which is very weird and might actually be a Unity bug. The error I think has to do with Proyecto26.RestClient targetting .net 3.5 while I'm building .net 4.0, however if I drop the version to 3.5 in the compiler (which is now deprecated) the RSG.Promise_netstandard.dll is no longer compatible as that targets 4.0.

But I would have thought that .net 4.0 would support a .net 3.5 assembly..

What version of Unity are you using?

[jdnichollsc]

Can you rename the dll of RSG.Promise to RSG.Promise.dll?

[jdnichollsc]

On the other hand, do you have a link.xml file?

• https://docs.unity3d.com/Manual/IL2CPP-BytecodeStripping.html
• https://docs.unity3d.com/Manual/dotnetProfileAssemblies.html

Something like this:

<linker>
       <assembly fullname="Proyecto26.RestClient" preserve="all" />
       <assembly fullname="RSG.Promise" preserve="all" />
</linker>

or

<linker>
       <assembly fullname="Proyecto26.RestClient">
               <type fullname="RSG.Promise" preserve="all"/>
       </assembly>
</linker>

Let me know

[jdnichollsc]

If you want I can generate other dll of Proyecto26.RestClient for .NET Standard.
I apologize for the inconveniences, I do not have much experience with Unity

[meds]

I think it's fine the way it is, but perhaps the latest version of the plugin shouldn't have DLLs for the older versions of Unity, but that's just my opinion and isn't something that necessarily has to happen.

Thanks for your help!

[jdnichollsc]

all users don't have the last version of Unity :/

[jdnichollsc]

@meds on the other hand, you can use RSG.Promise.dll (net 3.5 version) with .NET 4 except in UWP because .NET Standard is required to support that platform.
