dsharp.save/load with BinaryFormatter is blocked on .NET Interactive

Issue #440 | Created by @nhirschey | 2022-10-11 21:42:05 UTC |

Related to PR #430, .NET Interactive blocks BinaryFormatter, so this prevents model saving and loading in F# notebooks.

TorchSharp seems to be using BinaryWriter to get around this (e.g. here)

This is in VSCode using .ipynb notebook

#r "nuget: DiffSharp-lite"
open DiffSharp

dsharp.save(dsharp.tensor([1..10]), "test.params")

cell output:

Error: System.NotSupportedException: BinaryFormatter serialization and deserialization are disabled within this application. See https://aka.ms/binaryformatter for more information.
