WPF Project Folder File Bloat

I work on my WPF project daily in Visual Studio 2022, and back-up my project folder in the evening. I can't help but notice the number of files in there just keeps getting greater (by hundreds every day), even when I'm not adding anything new to the project. It's causing back-up time, and the time it takes to transfer my files between workstations, to get longer and longer.

What could be generating these extra files and is there a way to minimize it?

I've had a look around the net for answers, but to no avail.

Thanks for all and any advice you can give me.

The best way to solve your problem is using the GitHub Repository.
Go to the Git Studio menu, select the create repository item in it, upload your Solution to the created Repository, commit the changes when you need it.
In addition to just backing up, this will allow you to easily and conveniently compare different versions.

If for some reason this is inconvenient for you, then pay attention to the ignore file in the Repository. All templated files and folders in this file do not require backup.

Here is a link to the ignore file from my Repository: https://github.com/EldHasp/CyberForumMyCycleRepos/blob/master/.gitignore

In the most minimal variant, all folders whose names begin with a dot, the bin, obj and packages folders do not require saving.

Try the following:

1. Try compiling in release mode instead of debug mode.
2. Try clearing the obj and bin folders
3. Turn off the automatic generation of xml.

Update:
My guess is that you are running your program in debug mode and your program is causing some files to grow.
There are the following methods to clean up the obj folder:

1. Right-click the project and select clean, then rebuild
2. Add the following code into the pre-build event, so that the obj folder will be cleaned up before each build, but this operation will delete the previous obj folder.

rmdir /s /q "$(ProjectDir)obj"
