The visualizer tool doesn't work - VS 2017 Enterprise

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.

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

Solved after download of framework .net472, because it wasn't installed on my pc.

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?
