ReBuild output produces backup files in Visual Studio 2022

Question

We have multiple projects in VS 2022 mostly using VB.Net.

When we do a Rebuild Solution on a project, the results sometimes produces backup files of our output files.

Example: We have a simple application with 2 projects that also use Newtonsoft.Json.dll.

When we first compile this Solution, the output folder shows 3 files;

MyApp.exe

MyApp_Data.dll

Newtonsoft.Json.dll

Later we do another Rebuild Solution

The output folder now shows the following

MyApp.exe

MyApp_Data.dll

Newtonsoft.Json.dll

MyApp 2.exe

MyApp_Data 2.dll

Newtonsoft.Json 2.dll

This numeric "backup" will continue (3, 4, 5 ...").

Note: not ALL Rebuilds seem to generate the extra backup files.

How do I stop this from occurring if we don't want this to happen?

Thanks,

Steve

Hi @Steve Finner , 

Welcome to Microsoft Q&A! 

Could you create a new project and check if it occurs in other projects? I tried it on my side and couldn’t reproduce the issue. 

You can try the following workarounds:

1. Update your VS2022 to the latest version with Visual Studio Installer.
2. Enter “devenv /ResetSettings” at Developer Command Prompt for VS 2022 to restore your Visual Studio default setting.
3. In your project properties > Build Events, please check if you use a build event to customize the project’s build. 

If it persists, maybe you can check the detailed output by setting Tools > Options > Projects and Solutions > Build And Run > MSBuild project build output verbosity option to Detailed. 

Sincerely,

Anna
