Hello,

I am developing a project in Unity. I have imported different nuget packages in Unity. But for most of the packages I am getting this error. Did anyone face this problem before? Please let me know how can I resolve this problem.

I am running on API Compatibility Level .Net 4.x

Are those .net Core packages?
no Core doesn’t work with Unity’s Mono, and there are no news about it.

I have solved the problem. The problem was that I have added the dll by downloading through NuGet and added them in Plugins folder inside Unity project. That probably created some dependencies that they were working inside the editor but the dll was unable to find the corresponding package when building the app. That’s why I was getting “Could not load signature” error.

The solution came by using NuGetForUnity that automatically downloads NuGet packages and translates them to unity packages.

I hope this answer may come in handy.
