"System.ObjectDisposedException: Cannot access a disposed object."

[j.jemine]

I’m facing this error when creating a simple Linux project (Gnu Make, all default options) in VisualStudio 2017:

The project ends up being created but not the vgdbsettings files, so it’s a standard C++ project.

Any idea?

I was having the problem when adding a new project to an existing solution.

It worked when I created the same project in a blank environment. I then copy-pasted the .vgdbsettings files.

Hi,

Thanks for the very detailed description. It looks like an internal exception in the Visual Studio Automation logic used by VisualGDB to create some project types. It used to get triggered a lot in early preview builds of VS2017, but was fixed after we filed a bug report with Microsoft. This might be another instance of it, or a completely different bug.

We tried quickly reproducing it (creating a new Make-based project in a solution that already has a project), but could not get it to crash. As it might be a glitch in one of the recent VS2017 updates, our advice would be to keep on using the workaround until the next VS update (15.8) rolls out. If the issue persists after the next VS update, please try reproducing it from scratch (i.e. first create a new solution with a new project, then add another project) and share the exact choices you make in the wizard so that we could try reproducing it on our side.

It has started happening with VisualGDB on my machine and also on another developer’s PC – pretty much simultaneously!

We both run VS2019 v16.4.5 and VisualGDB v5.4 R12.

The only common theme is that VisualGDB support has expired a few days ago, but it is still a fully licensed copy on both PC’s.

Does VisualGDB stop creating new projects within an existing solution if its support period has expired???

Please let us know what is the solution to this, because this sudden symptom on two separate computers looks very questionable.

Hi,

Based on the logs you attached, the exception is happening inside the VC++ project engine (Microsoft.VisualStudio.Project.VisualC.VCProjectEngine).

Most likely, Visual Studio has recently installed a minor update on both computers that started triggering the error. You can try reverting to the previous VS version and check if it resolves the problem, or alternatively report this to Microsoft support and see if they can fix it on their side.

Based on our experience, the ObjectDisposedException may occur sporadically inside the VC++ project engine, but reloading the solution while deleting the .vs folder often solves it. Either way, if you find this annoying, please consider using the Advanced CMake project subsystem (or other advanced project subsystems shown here). They are not based on the VC++ project type and won’t trigger this error.

Edit: If you suspect that the VisualGDB’s license checking logic is incorrect, we can temporarily extend the expiration date on your licenses in our system, and you can recheck if it changes anything.

Support,

Thank you for your prompt response!

We can add a new Linux project to a blank Visual Studio solution just not to the one that started throwing the error.
Tried deleting .vs folder and even the entire solution folder and pulling it again from Git – same error on adding a project to an existing solution.

Switching to CMake is not a good option for us, since we have a number of projects relying on QMake in this solution, so it is a lot of effort to re-work the entire build system.

Is the workaround to copy-paste .vsgdbsettings files between those projects from different solutions? Are there any other workaround steps that should be performed?

Thank you, Alex

Sorry, that would qualify as a technical support question and hence we would kindly ask you to renew your licenses, if you would like us to help resolving this.

If you do not wish to renew, please have a look through our documentation and tutorials. They may contain the answers to your questions.
