Hi Jayani,

Right so you still get this error:

IAstRuleReturnScope sounds like it might be something in your
code, or in the C# code that was generated by the antlr tool
from the .g files, or maybe something in the C# antlr runtime.

You could try:

- checking the C# files generated from the antlr tool are linked into the
- searching for IAstRuleReturnScope in the generated C# files, and in the .g
- searching for IAstRuleReturnScope in the C# runtime
- searching for IAstRuleReturnScope in the string template files (.stg) for
  the C# runtime in the antlr tool source code

Actually its in there, maybe that gives some more hints:

% grep IAstRuleReturnScope **/*.stg
tool/src/main/resources/org/antlr/codegen/templates/CSharp2/AST.stg:, IAstRuleReturnScope\<<ASTLabelType>\>
tool/src/main/resources/org/antlr/codegen/templates/CSharp3/AST.stg:, IAstRuleReturnScope\<<ASTLabelType>\>
tool/target/classes/org/antlr/codegen/templates/CSharp2/AST.stg:, IAstRuleReturnScope\<<ASTLabelType>\>
tool/target/classes/org/antlr/codegen/templates/CSharp3/AST.stg:, IAstRuleReturnScope\<<ASTLabelType>\>
