System.Memory dependency

Hello guys, I’m trying to use some NUGET packages downloading them online unZIPing and placing the dll under Plugins folder inside my Assets folder.

But for some reason, always when I try to use a dll that has System.Memory dependency it generates this error:

Error: Could not load signature of ServiceStack.Command:get_Original due to: Could not load file or assembly ‘System.Memory, Version=4.0.1.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51’ or one of its dependencies. assembly:System.Memory, Version=4.0.1.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51 type: member:(null) signature:

I’m not well familiar with c# scripting and from my searchings online it looks like an assembly bind redirect would work. But I hadn’t success trying that on unity projects.

I’m currently using macbook macOS Catalina to develop my project.

any update on this . i am running in the same issue
