I'm writing a client in c# using VS 2019, which includes a GUI in WPF (this is my first project in WPF). When I ran the project I got errors which say that there are multiple declarations for several attributes -
Duplicate 'attribute' attribute
I checked the file the error came from, which was an .AssemblyInfo.cs, and saw in the file explorer that several other files which are identical were created.
As I didn't want to change the files at the client, I created a new WPF project to experiment and understand the problem. I ran the program, and it worked. I decided to run it after adding another window, to simulate my client better, and it still worked.
For now, I don't want to continue trying and experimenting because I think that I reached the limit of my experimental project, and I don't want to edit files I don't understand in the main project.
Unfourtantly, I don't know any way this problem is duplicatable on another computer, but I think creating a WPF project would give a good sense of what is going on.
