Antlr4 C# WPF build problem

[skulma01]

Hello,

I have a hard time building ANTLR4. I tried to create a simple language just to get used to ANTLR4 but with no success.

1. Added ANTLR4 and ANTLR4.RUNTIME in nuget package
2. Created grammar and build with succes
3. Created class CalculatorVisitor
4. Build without success - error CS0246
   I don't know why. I have this problem in WPF application but not in console application.

The compilation error could be caused by a number of issues. I would check that the package statement is the same between MainWindow.xaml.cs and the generated files for the visitor ArithmeticBaseVisitor.cs and parser ArithmeticGrammarParser.cs. In the future, please post the code since pictures of the IDE do not show the entire code, including the .csproj. Also, you should not be using antlr4 and antlr4.runtime. These packages are five years old, and unsupported. The official Antlr package to use is antlr4.runtime.standard. To do the build, you should add in my package antlr4buildtasks, a drop-in replacement for the build rules for antlr4. Antlr4BuildTasks fixes many bugs in antlr4.

Thank you very much. Tried the official Antlr with your package and it works fine.
