Debugging issues (F5 experience) "VCMessage" task failed unexpectedly

Hi there,

I recently updated to VS2017 (build 15.4.4) and re-installed Visual Micro.

Unfortunately this resulted in nothing but trouble.
What I'm trying:

- Create a new Arduino project from the Visual Micro menu 
- Hit F5 (my board and port settings are correct)

First I kept getting the: "The "VCMessage" task failed unexpectedly" error. Some searching here lead me to change my build configuration.

This resulted in a dialog: "Unable to start debugging. Check your debugger settings by opening project properties and navigating to 'Configuration Properties --> Debugging'. Going there shows me that the project has an "Unsupported debug option".

What I've tried furthermore:

- .ino file, project folder and solution name are all the same
- reinstall visual micro
- remove everything other than the .ino file from the project
- create a new project

All to no avail. 
However, despite these errors, the project IS being built and uploaded.

I'm kinda stuck now... The dialog boxes are so annoying I won't be able to work with Visual Micro anymore. Any thoughts?

Hi,

It's possible another extension is attempting to run an event after build or that gdb has been enabled.

You can switch off the project from Visual Studio builds and events in "Build>Configuration Manager". Visual Micro does not need anything to be checked in that window.

One question is to confirm the sane things happens if you use "File>New>Project>Visual C++>Arduino Project"?

Hi, thank you for your reply.

The project is already switched off from Visual Studio build, as far as I can tell. That was the first thing I tried.

Same thing happens when I try "File>New>Project>Visual C++>Arduino Project".
I get a warning that the project is out of date and needs to be built. Switch off VS builds. Warning "Unable to start debugging".

I'm pretty annoyed because I bought the pro version and it's now completely useless.

Are you sure "vMicro>Automatic Debugging" is checked and not "vMicro>Use Visual Studio Debugging"?

What happens if you click "vMicro>Build & Upload"?

Visual Micro does not use Visual Studio for build or for debug. So some config is causing this. Please show screen shot of your ide.

Automatic Debugging was off, turning it on made no difference.

It builds and uploads.

Visual Micro does not use Visual Studio for build or for debug. So some config is causing this. Please show screen shot of your ide.
arduino1.png is the error message
arduino2.png is my build configuration and the project properties suggested in the error message.

Hi,

If you had switched off automatic debugging then you have been fiddling Smiley

+ Debug will not start because you have the tool bar set to Release and not Debug.


The issue you are having is related to another C++ extension that you have installed that is trying to do something it should not.

I suggest you uninstall all extensions except Visual Micro and prove the issue. I can confirm that the cause is not not a part of visual micro.

Thanks

Hi, thanks for getting back on this again.

I've been fiddling because it was not working, haha.

Also, my issue is not that debug doesn't start, it is that Visual Studio tries to do a build, where it shouldn't. (Or at least I think that is what's happening.)

The only extension I can think of is Resharper, I will try again tonight.

Problem seems to be caused by a defective Xamarin install.

Removed that and now VisualMicro is working as I want it to.

Thanks for the help!
