Debugging NetStandard 2 assembly fails with "Unable to break execution 0x80004005" #1901

itadapter · 2018-01-25T22:35:15Z

.Net Standard Assembly. Using .NET 4.7.1 launch project - a console app linking DYNAMICALY (via Assembly.load()) to the target DLL. The breakpoints are not hit. The PAUSE does not work. VS 2017 15.5.5; tried running as admin; does not help.

An attempt to Pause the process:

Anyone can shed some light?

@gregg-miskelly Do you know what might cause the debugger to error out with that message?

@itadapter Is this happening on multiple machines? Can you share a minimal repro project that causes this?

gregg-miskelly · 2018-01-25T22:53:36Z

If you go to the processes window (Debug->Windows->Processes) what does the 'Debugging' column say?
If you go to the modules window (Debug->Windows->Modules) is the modules window empty?

itadapter · 2018-01-25T22:57:50Z

Debugging processes: (trun.exe as expected)

Debugging modules: EMPTY

Keep in mind, the target assembly(to be debugged) is loaded dynamically via Assembly.Load(....)
I tried running VS as Admin, updated to 15.5.5 - all to no avail
also, I just figured that this shows up IF I use launch settings, that is: I set assembly as a stratup target with EXE as a debug launch command. IF I use the hand -written EXE in the same solution that calls the same code (including dynamic assembly load), it works as expected.

I believe the problem is that your debugger is configured to debug with .NET Core, but you actually want to debug .NET Full-framework.

What kind of project is your startup project? (Classic .NET Project or .NET Core), (Web/Console/WinForms)

itadapter · 2018-01-25T23:02:28Z

.NET 4.7.1 The assembly is .NET Standard 2.0
And debugging works if you swithch roles - set the EXE as a startup target vs .DLL with EXE launcher

At any rate, it should be then giving some error but not run and fail to pause the process. It does run/terminate as expected, the breakpoints are all "RED"/active but they dont stop

@nguerrera No it is on a single machine dont have "simple project", have full thing here:

I see the repro now:

File -> New Project -> Class Library (.NET Standard)
Project properties -> Debug:
- Launch -> Executable
- Executable -> Path to .NET Framework application

Something is deciding to use the CoreCLR debug engine here and I'm not sure how to override it. cc @BillHiebert

itadapter · 2018-01-25T23:22:16Z

@nguerrera yes it looks like it. Like I said, if you happen to have a LAUNCH EXE in the same assembly then set it as a startup (dynamically linking to .NET Std 2) then all works OK.

This is what I am doing now - creating a fake test container in the target solution to get around this problem

alelom · 2021-10-15T09:20:00Z

@itadapter I'm facing the same issue, could you elaborate more on your workaround?
How do you make this fake test container?

@alelom that was 3 years ago, just moving to the next version of VS/fx fixed it, not sure what else changed
