I am using Visual Studios 2022 to make a Windows Forms application with C# .NET core 6.0
The program seems to function without any errors, but whenever I attempt to publish the build to a local folder, I get this error message. I was getting this message once before and I repaired my installation. After the repair, the program built and published fine on the first attempt. I changed a large amount of the code, built again and had no error. On the third attempt, however, after changing another large chunk of code, the issue reappeared. I tried to lookup the reason for this error, but I can't seem to find anything for Visual Studios 2022 or .NET core 6.0
I'm not sure what I can do to fix this. It does not seem to affect the build, but I would like to know the cause so I can prevent this and any effects I have not yet noticed.
EDIT: This is now also occurring whenever I try to save the project or even just change tabs to a different form, but not the actual .cs files. The form files still display properly after clearing the error message, and the build finishes successfully, but this is really bothering me because I cannot save any of the files.
Did you see this error message when working in Visual Studio?
Yes, it appears whenever I attempt to save any of the files or switch tabs to/open one of the form design files
Have you checked Windows event log?
Also, what type of work is being performed and when does the app crash, at startup? If so what is the code doing and if not at startup what actions are taken leading up to the crash?
It is a program to backup/duplicate directories. I have not checked the Windows event log, how do I do that?
Running the program doesn't cause the issue, it is only whenever I attempt to save it or open the tab with one of the form.Design.cs files.
Weirdly enough, last night I copied all of the files to .txt files outside of visual studios so I could close it without risking losing anything, and when I reopened visual studios this morning it seems to all be in working order. The error is no longer showing up, and the program seems to be doing everything it needs to. Hopefully this issue is over, but I'll let you know if it happens again.
When something does not work and should there are two immediate paths, setup logging to a file and also check windows event logs, second close/re-open Visual Studio, clean/rebuild...

Hi @WowGeeWhiz ,Is there any update in this issue?
No, I haven't had any more issues with my program so far. I have no clue what was causing the error, but it seems to have resolved itself and the program is working fine.
The .NET Core WinForms visual designer in Visual Studio is still a preview, so don't expect it to be bug free. There are already minor issues here and there.

I have been getting the same error. It occurs sporadically when running my Windows Winform app (using .net core 7).
Strangely it doesn't prevent my app for running, nor prevent me from saving the project.
It also occurs occasionally when building the project.
I'm not sure if it is related, however, it began when I ran the project in debug mode, then attempt to open the design view for the form, which was already open, and an error prevent me from doing so. I don't recall the error. I closed the design view, reopened it, and it was then fine, until another "build" with this form open and active.

I'am getting same error,same project type and dotnet version,iam wandering if it has to do with Onedrive syncing process.
