I am not sure if the output format is what would be desired. This is basically the default .ToString() that .net provides. Maybe we want individual labels and fields? I didn't want to over-complicate the first past on this. Your considerations and suggestions are greatly appreciated.

Wow, what a great pull request! Thank you so much for this! I will need some time to test it myself.

Meanwhile, as a heads up, we're working on DevToys 2.0, which will be made in .NET 7.0, and I see there's a specific comment about that. Glad to see .NET 7.0 would hopefully simplify the implementation :D

@btiteux, mind taking a look at this PR too?

[jlevier]

Thank you so much. So glad to hear about .NET 7.0! I knew DevToys 2.0 was cooking but I hadn't had a chance yet to see what is in the release.

Ok hopefully all issues above are addressed now. I have left the commit separate for easy comparison and can squash later after review.

Hello,

Again, this PR looks great! Just a few details remaining.
As a heads up, I will be traveling from tomorrow to May 9th. This PR is almost ready to be merged. Once done, I'd be happy releasing an update with this new tool, but it will likely not happen before mid-May-ish :D

[jlevier]

I just greatly appreciate you taking the time and providing feedback, so please there is no rush. I will have a follow up commit to your latest findings soon. Hope you have safe travels!

[veler]

PR approved! :D Thank you again for this contribution! Will merge it and wait a few more days before publishing it, just to give a chances to translators to translate this tool in many languages.
