Error message BC31502 "Resource name ___ cannot be used more than once"

Question

When trying to run my project, I keep getting this error message Error message BC31502 "Resource name ___ cannot be used more than once".
It shows me the File location of the error "vbc", but there is no such file in that directory that is being specified.

Hi @Simon ,

Welcome to Microsoft Q&A!

Which version of Visual Studio are you using? What is your project type?

It seems that the name of a specified resource is used more than once.
Please click on “Show All Files” on the solution explorer and check if you can find two resource files. You can delete the second one like .resources1.

If it doesn’t work, please close all VS instances and delete the hidden .vs, bin and obj folders in the project folder.
Then, relaunch your VS to run again.

Sincerely,
Anna

Answer 2

Microsoft Visual Studio Enterprise 2022 (64-bit) - Current
Version 17.2.2

my projects are vb.net, target framework 4.8

all my projects suddenly became damaged after clients are using the application and haven't had a problem.
This occurred after updates came in automatically from VS2022.
I think that the new updates are not compatible with the method that VS is using Framework 4.8. Because the errors that are being generated are not the usual errors that are standard in a Microsoft project.
It doesn't make sense that all my projects should become damaged all at once, and suddenly error messages are coming up one after the other.
What could this mean?
