Replace obsolete BinaryFormatter

[cristipufu]

Tried to update to net8.0:

• Fixed The call is ambiguous between the following methods or properties ProcessEnvironmentVariablesInternal.AsReadOnly()
• Replaced BinaryFormatter with System.Text.Json serialization https://learn.microsoft.com/en-us/dotnet/core/compatibility/serialization/7.0/binaryformatter-apis-produce-errors
• Followed the guidelines here [Breaking change]: Legacy serialization infrastructure APIs marked obsolete dotnet/docs#34893 to fix the System.Exception-derived type serialize issues

I confirm that the pull-request:

• Follows the contribution guidelines
• Is based on my own work
• Is in compliance with my employer

I think maybe we should not introduce a new external dependency in the form of Newtonsoft.Json and implement by using System.Text.Json - https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json/migrate-from-newtonsoft?pivots=dotnet-7-0.

@matkoch can you please take a look? is there something I can help with to speed up the update?

[cristipufu]

net8-rc1 has been released

Hi @nsentinel, @cristipufu we are very waiting for this also :)

@matkoch kind reminder

[cristipufu]

FYI as a workaround you can add <EnableUnsafeBinaryFormatterSerialization>true</EnableUnsafeBinaryFormatterSerialization> in .csproj

I might be mistaken, but I think you might have accidentally changed the encoding of the non-generated files in this PR.

Thanks for the PR, but unfortunately it's not working. I decided to suppress the warning for now and approach the issue in a year again.
