IDmkClrExpressionCompiler.CompileExpression: wrong value in "Text" property of DkmLanguageExpression about concordextensibilitysamples HOT 4 CLOSED

@onor13 the language service is responsible for deciding what expression is under the mouse cursor.

Hello Gregg-Miskelly, do you know which part/interface(s) ? It seems strange to me, because my issue is with the debugging session: mouse hover to see the VALUE of a variable/token. It has nothing to do with mouse hover of IntelliSense or similar Language Service functionalities.

@onor13 yup, this has nothing to do with putting up completion lists. But deciding what is the extend of an interesting identifier is a language-specific concept, and hence a language service is what decides what should be evaluated.

The hookup between the editor and language services is not something that I really understand. For C#, at least, the language service directly calls the debugger last time I looked (IVsDebugger.GetDataTipValue) but I am not sure if that is required, or if the editor will sometimes call that on the language service's behalf. In case it gives you some hints, I think this is the Roslyn code for it: https://github.com/dotnet/roslyn/blob/9d94537786ba0561cc1c55fbd298c82388e8a5af/src/VisualStudio/Core/Def/Implementation/LanguageService/AbstractLanguageService%602.VsLanguageDebugInfo.cs#L406

Thank you a lot Gregg, the Roslyn code does exactly was I was looking for.
