As an immediate workaround, you could download the NuGet ValueTuple package and extract the dlls into the visualizer folder.

I'll look into a more permanent solution.

@BrunoParrotta I'm guessing this is because you're targeting .NET Framework 4.7.2, and value tuples were only introduced in 4.7.

If you open the above-mentioned NuGet package with an archiver, you want lib\net461\System.ValueTuple.dll.

@zspitz thank for your answer, but i put
System.ValueTuple.Dll got from system.valuetuple.4.5.0.nupkg
in the same directory of Antlr4.Runtime.ParseTreeVisualizer
but it doesn't work.... :_-(

Stack trace is the same.

@BrunoParrotta Your project is targeting .NET Framework 4.6.0, which only supports .NET Standard 1.0. Perhaps try the version in lib\netstandard1.0\?

I apologize for trying to find these hacky workarounds; I don't have the time right now to give this issue the attention it deserves. Perhaps in a few days.

[BrunoParrotta]

@zspitz Thank you for your support, but it doesnt' work...
Any other ideas?

[BrunoParrotta]

Solved after download of framework .net472, because it wasn't installed on my pc.
I thought it was....
this is the link. https://dotnet.microsoft.com/download/dotnet-framework/thank-you/net472-web-installer

After solved this my little trouble i can say that this is a great tool!
Congratulations for the work done!

That's great to hear, and I'm sorry I wasn't able to give this the attention it deserved.

Just to confirm: your project is still targeting 4.6.0?
