Target .net 6.0 (and later), removing newtonsoft dependency

[waynebrantley]

Issue Summary

Any chance on getting the library updated past netstandard 2.0. By targeting net6.0 and later, you can use system.text.json and not need newtonsoft. You can still create a netstandard 2.0 release with newtonsoft.

Hi @waynebrantley! Thanks for reporting the issue. This is on our radar. Pull requests and +1s on the issue summary will help it move up the backlog.

@rakatyal there are 12 prs now and concerned that large changes like this will not be merged if a PR is created. Can you assure that PRs with changes that are needed like this will not just sit as a PR with no one touching?

[waynebrantley]

@rakatyal Any update? As a developer centric product (Twilio really, really relies on developers to help them grow) - this library should be brought up to date and target at least net6 and remove these dependencies. In addition, I think you should really engage and handle all these now 15 prs as they just age out. No community member is going to do this - because the PR will just sit there.

This problem appears to be a problem across Twilio. twilio/twilio-voice.js#55

@Swimburger @AsabuHere @rakatyal Any update. Need to use System.Text.Json. Additional targets for dotnet 6,7,8 etc would be nice too.
Developers are your bread and butter. Without them - twilio would cease to exist. You really should embrace your projects and keep them up to date.

@waynebrantley System.Text.Json is supported on netstandard2.0 too, so the Twilio library should be able to use those APIs on all supported versions of .NET, except for .NET Framework 3.5. .NET Framework 3.5 could keep using Newtonsoft.Json.

[waynebrantley]

@Swimburger agree - just need to get it done. Those on netframework 3.5 dont have to upgrade either. Hard to believe people are still on that... 5.5yrs left on support for it...so time is ticking down!

Any movement inside Twilio to get this done?

[Swimburger]

@waynebrantley I don't have visibility on that as a former Twilion, but I don't expect this to be done anytime soon.

Came to this problem for the same reason when I saw the use of Newtonsoft.Json. It's really a bit disconcerting how this project evolve so slowly in the face of changes in the .NET ecosystem, mainly when is the SDK project of a well know company like Twilio. Newtonsoft library was deprecated for .NET Core 3 at Sep 23, 2019, we are using .NET 8.

We tried to address this issue in version 7.0.0 however this issue (#732) came up as people were still using previous versions.

Removing .NET Framework support doesn't make sense since it's still highly in use.

The built-in JSON library System.Json.Text is supported on .NET6, .NET Framework 4.6.2, and .NET Standard 2.0.
In fact, you could just build for .NET Standard 2.0 and then .NET 6+ and .NET Framework 4.6.2+ would use that build.

You can remove newtonsoft.json and replace it with System.Json.Text.
Newtonsoft.json very often causes issues because so many libraries depend on different versions of the library causing version conflicts. So not taking that dependency would reduce friction for users of this library.

[tiwarishubham635]

Sure, I'll check that

[tiwarishubham635]

I was checking here and it says we need .NET Framework 4.7.2+. Won't that be an issue for many users?
