$CALLSTACK and $CALLER in Debugger Trace points about concordextensibilitysamples HOT 4 CLOSED

Have you implemented an expression evaluator? If not, those strings will be coming from the default expression evaluator. I am guessing you have a .NET-based language? If so, the default is the C# expression evaluator and I believe will obtain the class/method names from metadata.

IVsLanguageDebugInfo is not used for all that much. From what I recall, GetNameOfLocation is used get the names of methods to display in the breakpoints window when a breakpoint isn't bound yet. There may be a few other uses that I am not thinking of, but 98% of the information that the debugger shows about the target program are going to come from the debugger rather than the language service.

@gregg-miskelly Yes, we have implemented an expression evaluator (also based on the Roslyn expression evaluator).
Do you have any idea which method / property is called to retrieve these values ?
I see that GetNameOfLocation is called and also GetProximityExpressions. We have implemented both and they work. We see the names of the methods and the autos window is also filled.

I would expect it to call IDkmLanguageInstructionDecoder.GetFrameName with DkmFrameFormatOptions.ArgumentFlags=DkmVariableInfoFlags.None and DkmFrameFormatOptions.FrameNameFormat=DkmFrameNameFormatOptions.Module

Thanks, that helped.
