I am using the Microsoft.Graph library and I am getting this exception upon sending an email. The full exception is:

System.TypeInitializationException: The type initializer for 'Azure.Core.ClientOptions' threw an exception.
---> System.IO.FileLoadException: Could not load file or assembly 'System.Memory, Version=4.0.1.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

I have tried adding a binding redirect but all I got was another error saying that System.Memory was not found at all. I don’t know what else to try. Do I:

1. Install System.Memory to the same lib that has Microsoft.Graph?
2. Remove the binding redirect and do option 1?

Either way, the only versions of System.Memory I can find on nuget right now are: 4.5.5, 4.5.4, 4.5.3, 4.5.2, 4.5.1, and 4.5.0. What else can I do?
