Breakpoints do not break for generated code #27

Closed manureini closed 5 years ago

manureini commented 5 years ago

Hello,

Thank you for this great debugger. It's working for me with compiled code in vs. But when I generate an assembly with roslyn a breakpoint does not break.

I created a small sample project:

https://github.com/lordmampf/PlaygroundForSamsungNetcoredbg To test start both projects without the vs debugger. When using roslyn a breakpoint does not work.

Do you have any ideas how to fix this issue? Is this an issue with the debugger?

Thank you!

Hello! Thank you for the kind words! In order for breakpoints to work you need a PDB file with debug info alongside your DLL.

I guess you need to add some EmitOptions with DebugInformationFormat.PortablePdb (see https://docs.microsoft.com/en-us/dotnet/api/microsoft.codeanalysis.emit.debuginformationformat?view=roslyn-dotnet)

Maybe a thread on StackOverflow could help you: https://stackoverflow.com/questions/50649795/how-to-debug-dll-generated-from-roslyn-compilation

Hello ;)

Yes sure, I forgot that in this example. Now I use the code from stackoverflow to generate the assembly.

I'm getting an breakpoint changed event with verified = true, but the breakpoint still does not break.

It will not break, because of #20 and #19 .

Hello,

Thank you very much for your help! It's working now.

My mistake was, that I had to remove the compiled code from the project. Because the sourefile was used in two different assemblies.

@lextm I tested https://github.com/lextm/netcoredbg/commit/0fcaf6877d3085b18049d2bdeca69685db561b94 on your test branch. For me it's working with this version and your version as well.
